Cisco delivers OC-192 Circuit Emulation to Verizon

Verizon is currently carrying customer traffic on part of its transport network using a new highly scalable circuit emulation solution from Cisco that supports speeds up to OC-192. Previous circuit emulation equipment carried speeds up to OC-12.

Circuit emulation enables transport of conventional digital and optical signal rates over a packet-based MPLS network without impacting customer traffic -- creating a smooth migration of legacy services to next-generation infrastructure and improving overall reliability.

As part of its next-generation 100G U.S. metro network rollout, Verizon initially deployed this technology where it could aggregate multiple Ethernet and TDM circuits at the same location onto a unified high-speed circuit.

“This is a true architectural collaboration with Verizon. We have worked hard to deliver this unique solution that will easily enable the growth of Ethernet services while improving the reliability of mission critical TDM private line services,” said Bill Gartner, vice president, optical systems and optics, Service Provider Business, Cisco.

Verizon Picks Cisco and Ciena for Advanced 100G Metro Network

Verizon has selected Ciena and Cisco as vendors for its next generation metro optical network.

Specifically, Verizon will test and deploy Ciena’s metro-optimized 6500 packet optical technology and the Cisco Network Convergence System on portions of its 100G metro network this year, with plans to turn up live traffic in 2016. Supplier volumes will be guided by ongoing testing, support and performance.

“Deploying a new coherent, optimized and highly scalable metro network means Verizon stays ahead of the growth trajectory while providing an even more robust network infrastructure for future demand,” said Lee Hicks, vice president of Verizon network planning. “Ciena and Cisco met not only our technology requirements but the aggressive timeline to deploy our next-generation 100G-and-above metro network.”

University of Guam lights 100G GOREX

The University of Guam is now connected to the global Research and Education Network fabric at 100G.

The GOREX network—or Guam Open Research & Education eXchange—connects Guam to Hawaii and California via the new SEA-U.S. fibre-optic submarine cable.

The Marine Laboratory and the Water Environmental Research Institute at the university are two of the academic groups expected to benefit the most from GOREX at the onset, although UOG president Robert Underwood believes the true impact to the island community is in the opportunity for data access, exchange, and analysis in other fields such as healthcare, economics, and the social sciences.

“We can now conduct research at complex levels, not just for the sciences, but in other fields as well,” said Underwood. “Think about the issues that we discuss as a society and how we make many decisions with limited data. GOREX gives our students and faculty the tools to truly exchange and analyze large amounts of data in any number of fields with other institutions all over the world. And as a university, it is our responsibility to report our findings back to the community. That’s the impact.”

Sweden's Norrsken First to Deploy Infinera XTM II and 400G Flexponder

Norrsken, a Sweden-based regional operator, is the first to deploy the Infinera XTM II and the recently released 400G Flexponder. The carrier operates a regional network in Sweden providing Layer 1 wavelength division multiplexing (WDM) services and Layer 2 Ethernet services.

The equipment will be used for new 100 Gb/s services to leading internet service providers and carriers. Infinera said its XTM II platform and 400G Flexponder enable network operators like Norrsken to activate multiple 200 Gb/s wavelengths on a fiber, providing up to an eightfold density increase and a reduction in power per gigabit of 3.5 times over the previous generation of 100 Gb/s technology.

“We are excited to be the first carrier to deploy Infinera’s newly released XTM II platform and the new 400G Flexponder,” said Björn Jonsson, CEO at Norrsken. “This state-of-the-art network upgrade allows us to expand our end-user offerings to include 100 Gb/s services and scale to meet increasing traffic demands from our rapidly growing customer base. This upgrade delivers higher capacity, higher density, ultra-low latency and lower power consumption while keeping our existing chassis and protecting our network investments with this market-leading packet-optical platform.”

“The XTM II platform is the ideal solution for Norrsken’s network upgrade,” said Karl Thedéen
Senior Vice President, Metro Business Group, Infinera. “By delivering the 400G Flexponder as committed to the market and upgrading Norrsken’s network to the XTM II platform as planned, Infinera is helping Norrsken benefit from industry-leading innovation, meet mounting customer demands and win in its market.”

Infinera Intros XTM II for Cloud Scale Metro Packet-Optical

In June, Infinera introduced its next generation packet-optical platform for metro networks. The XTM II, which delivers Layer 0, Layer 1 and Layer 2 services, is optimized for bandwidth-intensive cloud scale applications at the metro edge, such as Remote PHY, 5G transport and data center interconnect (DCI). The new platform builds on Infinera's XTM Series, but now adds 200 gigabits per second (200G) per wavelength capabilities, with an eightfold density increase and a reduction in power per gigabit of 3.5 times. Power consumption is believed to be the lowest in the industry for 100/200G transport. It also features Infinera Instant Bandwidth, which is the company's open grid line system with SDN control. This gives network operators a highly flexible, open and software-programmable packet-optical solution for Layer 0, Layer 1 and Layer 2 services.

A key component of the XTM II platform is the new range of 200G per wavelength traffic units, featuring:
  • The 400G Flexponder: A dual, 200G muxponder that uses 16QAM (quadrature amplitude modulation) for high-capacity transport, or a dual 100G transponder that uses quadrature phase-shift keying (QPSK) for longer reach operation. This device provides 400G of line and client capacity per slot, giving an eightfold density increase over the previous generation. Including optics, the device operates at as low as 20 watts per 100G service, which the company believes is the lowest power consumption per 100G available in the industry on any wavelength-division multiplexing (WDM)-based platform.
  • The 200G Muxponder: A 200G Layer 1 muxponder that supports a broad range of client signals, including 10G/40G/100G Ethernet and Optical Transport Network (OTN) as well as 8/16/32G Fibre Channel. The device can also be paired to create an OTN add-drop multiplexer (ADM).
  • The EMXP440 Packet-Optical Transport Switch: A high-capacity addition to the existing range of EMXP devices that provides Layer 2 packet-optical switching with dual 100/200G ports and 12 or 24 10G ports. The EMXP440 supports Carrier Ethernet (CE) and MPLS-TP, packet transport with sub-50 milliseconds protection, Metro Ethernet Forum (MEF) CE 2.0 service creation and quality of service-aware traffic aggregation. In addition, the EMXP440 has feature-harmonization with the EMXP/IIe range and PT-Fabric.
Additional enhancements to the XTM Series include:

  • A new portfolio of XTM II upgraded chassis for improved power management and cooling and increased density to support nodes that require large volumes of new traffic units. 

  • Instant Bandwidth capability, enabling the on-demand licensing of 100G bandwidth increments to align capital expense spend with service revenue and to reduce operational expenses through automated software activation of new capacity.
  • New 400G+ per wavelength-ready flexible grid 4x and 9x ROADM modules and optimized hybrid erbium-doped fiber amplifier (EDFA)/Raman optical amplifiers to support sophisticated modulation formats and higher baud rates required above 100G. In addition, the new XTM II open flexible grid line system supports fiber capacity up to 24 terabits per second.
  • A unified solution providing end-to-end software control from core to access. The XTM Series, including the XTM II, is supported by Infinera’s Xceed Software Suite and DNA network management system. This new range of packet-optical platforms provides network operators with leading low power and high density at Layer 0, Layer 1 and Layer 2, and supports full interworking with the large installed base of XTM Series and the DTN-X platforms.

Infinera advances optical capacity with 100GBaud and 1024QAM milestones

Infinera announced two milestones for advanced coherent technologies:

  • pushing optical transmission to 100 gigabaud (GBaud) - this compares with typically deployed baud rates of 32 GBaud with the quadrature phase shift keying modulation carrying 4 bits per baud. Industry opto-electronics are moving to 66 GBaud development demonstrations. Infinera has surpassed this by being the first to showcase 100 GBaud using 32QAM to achieve a single-wavelength 1 terabit per second (Tb/s) data rate using multi-channel indium phosphide-based photonic integrated circuits (PICs) integrated with electronic driver and amplifier application-specific integrated circuits. This result was presented at the 2017 European Conference on Optical Communications (ECOC).
  • pushing modulation technology to 1024QAM (quadrature amplitude modulation) -- at ECOC, Infinera showcased the higher-order modulation scheme of 1024QAM using advanced constellation shaping algorithms and Nyquist subcarriers, allowing wavelengths to be spaced close to each other to maximize the data rate for a certain reach. The Infinera test bed used 66 GBaud at 1024QAM to reach 1.32 Tb/s, yielding spectral efficiency of 9.35 bits per second per hertz over 400 kilometers (km), an industry first.

The milestones are significant because they increase they enable the delivery of the highest possible capacity on a single wavelength for varied distances.

Optical transmission capacity is also a function of channel count, where multiple parallel wavelengths are combined on a single module to create a coherent super-channel. Infinera noted that as baud rates increase, placing optical components closer together on an integrated chip reduces component size and power while increasing reliability.  Its PIC technology uniquely enables high-channel-count coherent super-channels.

“Infinera is delivering optical engines at a faster cadence to help operators achieve exceptional capacity and reach performance on their transport network infrastructures,” said Dr. Dave Welch, Infinera Co-Founder and President. “As 5G wireless and cable video services take off, Infinera offers significant value to transport network operators by designing industry-first solutions.”

100G - Challenges for Performance and Security Visibility Monitoring

by Brendan O’Flaherty, CEO, cPacket Networks

The 100Gbps Ethernet transport network is here, and the use cases for transport at 100Gbps are multiplying. The previous leap in network bandwidths was from 10Gbps to 40Gbps, and 40Gbps networks are prevalent today. However, while 40Gbps networks are meeting bandwidth and performance requirements in many enterprises, the “need for speed” to handle data growth in the enterprise simply cannot be tamed.

As companies continue to grow in scale, and as their data needs become more complex, 100Gbps (“100G”) offers the bandwidth and efficiency they desperately need. In addition, 100G better utilizes existing fiber installations and increases density, which significantly improves overall data center efficiency.

A pattern of growth in networks is emerging, and it seems to reflect the hypergrowth increases in data on corporate networks just over the last five years. In fact, the now-famous Gilder’s Law states that backbone bandwidth on a single cable is now a thousand times greater than the average monthly traffic exchanged across the entire global communications infrastructure five years ago.

A look at the numbers tells the story well. IDC says that 10G Ethernet switches are set to lose share, while 100G switches are set to double. Crehan Research (see Figure 1) says that 100G port shipments will pass 40G shipments in 2017, and will pass 10G shipments in 2021.

Figure 1: 100G Port Shipments Reaching Critical Mass, as 40G and 10G Shipments Decline

100 Gigabit by the Numbers

The increase in available link speeds and utilization creates new challenges for both the architectures upon which traditional network monitoring solutions are based and for the resolution required to view network behavior accurately. Let’s look at some numbers:

100G Capture to Disk

Traditional network monitoring architectures depend on the ability to bring network traffic to a NIC and write that data to disk for post-analysis. Let’s look at the volume of data involved at 100G:




By equation (3), at 100 Gbps on one link, in one direction, a one-terabyte disk will be filled in 80 seconds. Extending this calculation for one day, in order to store the amount of data generated on one 100 Gbps link in only one direction, 0.96 petabytes of storage is required:


Not only is this a lot of data (0.96 petabytes is about 1,000 terabytes, equivalent to 125 8TB desktop hard drives), but as of this writing (Aug 2017), a high-capacity network performance solution from a leading vendor can store approximately 300 terabytes, or only eight hours of network data from one highly utilized link.

100G in the Network – What is a Burst, and What is Its Impact?

A microburst can be defined as a period during which traffic is transmitted over the network at line rate (the maximum capacity of the link). Microbursts in the datacenter are quite common – often by design of the applications running in the network. Three common reasons are:

  • Traffic from two (or more) sources to one destination. This scenario is sometimes considered uncommon due to the low utilization of the source traffic, although this impression is the result of lack of accuracy in measurements, as we’ll see when we look at the amount of data in a one-millisecond burst.
  • Throughput maximizations. Many common operating system optimizations to reduce the overhead of disk operations or NIC offloading of interrupts will cause trains of packets to occur on the wire.
  • YouTube/Netflix ON/OFF buffer loading. Common to these two applications but frequently used with other video streaming applications is buffer loading from 64KB to 2MB – once again, this ON/OFF transmission of traffic inherently gives rise to bursty behavior in the network.
The equations below translate 100 gigabits per second (1011 bits/second) into bytes per millisecond:



The amount of data in a one-millisecond spike of data is greater than the total amount of (shared) memory resources available in a standard switch. This means that a single one-millisecond spike can cause packet drops in the network. For protocols such as TCP, the data will be retransmitted; however, the exponential backoff mechanisms will result in degraded performance. For UDP packets, the lost packets will translate to choppy voice or video, or gaps in market data feeds for algorithm trading platforms. In both cases, since the packet drops cannot be predicted in advance because the spikes and bursts will go undetected without millisecond monitoring resolution, the result will be intermittent behavior that is difficult to troubleshoot.

Network Monitoring Architecture

Typical Monitoring Stack
The typical network monitoring stack is described in Figure 2. At the bottom is the infrastructure – the switches, routers and firewalls that make up the network. Next, in the blue layer are TAPs and SPAN ports – TAPs are widely deployed due to their low cost, and most infrastructure devices provide some number of SPAN ports. The traffic from these TAPs and SPANs is then taken to an aggregation device (or matrix switch or “packet broker”) – at this point, a high number of links, typically 96 10G, are taken to a small number of tool ports, usually four 10G ports (a standard high-performance configuration). At the top are the network tools – these tools take the network traffic fed to them from the aggregation layer and provide the graphs, analytics and drilldowns that form dashboards/visualization.

Figure 2: Typical Network Monitoring Stack

Scalability of Network Monitoring Stack

Let’s now evaluate how this typical monitoring stack scales in high-speed environments.

·         Infrastructure: As evidenced by the transition to 100G, the infrastructure layer appears to be scaling well.

·         TAP/SPAN: TAPs are readily available and match the speeds found in the infrastructure layer. SPANs can be oversubscribed or alter timing, leading to loss of visibility and inaccurate assumptions about production traffic behavior.

·         Aggregation: The aggregation layer is where the scaling issues become problematic. As in the previous example, if 48 links are monitored by four 10G tool ports, the ratio of “traffic in” to monitoring capability is 96:4 (96 is the result of 48 links in two directions) or, reducing, an oversubscription ratio of 24:1. Packet drops due to oversubscription mean that network traffic is not reaching the tools – there are many links or large volumes of traffic that are not being monitored.

·         Tools: The tools layer is dependent on data acquisition and data storage, which translates to the dual technical hurdles of capturing all the data at the NIC as well as writing this data to disk for analysis. Continuing the example, at 96x10G to 4x10G at 10G, the percentage of traffic measured (assuming fully utilized links) is 4x10G/96x10G, or 4.2%. As the network increases to 100G (but the performance of monitoring tools does not), the percentage of traffic monitored drops further to 4x10G/96x100G, or 0.42%.

It is difficult to provide actionable insights into network behavior when only 0.42% of network traffic is monitored, especially during levels of high activity or security attacks.
Figure 3: Scalability of Network Monitoring Stack

Current Challenges with Traditional Monitoring Environments

Monitoring Requirements in the Datacenter

Modern datacenter monitoring has a number of requirements if it is to be comprehensive:  
  • Monitoring Must Be Always-On. Always-on network performance monitoring means being able to see all of the traffic and being able to perform drill-downs to packets of interest on the network without the delay incurred in activating and connecting a network tool only after an issue has been reported (which leads to reactive customer support rather than the proactive awareness necessary to address issues before customers are affected). Always-on KPIs at high resolution provide a constant stream of information for efficient network operations.
  • Monitoring Must Inspect All Packets. To be comprehensive, NPM must inspect every packet and every bit at all speeds—and without being affected by high traffic rates or minimum-sized packets. NPM solutions that drop packets (or only monitor 0.24% of the packets) as data rates increase do not provide the accuracy, by definition, to understand network behavior when accuracy is most needed – when the network is about to fail due to high load or a security attack.
  • High Resolution is Critical. Resolution down to 1ms was not mandatory in the days when 10Gbps networks prevailed. But there’s no alternative today: 1ms resolution is required for detecting problems such as transients, bursts and spikes at 100Gbps.
  • Convergence of Security and Performance Monitoring (NOC/SOC Integration). Security teams and network performance teams are often looking for the same data, with the goal of interpreting it based on their area of focus. Spikes and microbursts might represent a capacity issue for performance engineers but may be early signs of probing by an attacker to a security engineer. Growing response time may reflect server loads to a performance engineer or may indicate a reflection attack to the infosec team. Providing the tools to allow correlation of these events, given the same data, is essential to efficient security and performance engineering applications.
A Look Ahead

100G is just the latest leap in Ethernet-based transport in the enterprise. With 100G port shipments growing at the expense of 40G and 10G, the technology is on a trajectory to become the dominant data center speed by 2021. According to Light Reading, “We are seeing huge demand for 100G in the data center and elsewhere and expect the 100G optical module market to become very competitive through 2018, as the cost of modules is reduced and production volumes grow to meet the demand. The first solutions for 200G and 400G are already available. The industry is now working on cost-reduced 100G, higher-density 400G, and possible solutions for 800G and 1.6 Tbit/s.”

Finisar shows 100G QSFP28 eSWDM at 300m

Finisar has demonstrated the first 100G QSFP28 eSWDM4 transceiver with extended reach for multimode fiber (MMF), which could enable data centre operators to upgrade from 10G to 100G without installing additional fiber.

The new device, which is a new member of Finisar's suite of extended reach QSFP28 form factor modules, leverages Finisar's SWDM4 technology and enables 200, 300 and 400 meter links at 100G data rates over OM3, OM4, and OM5 duplex MMF, respectively. Finisar now claims the longest fiber reach among duplex MMF solutions in the industry for 100G QSFP28 Ethernet applications.

In a demo at this week's ECOC 2017 in Sweden, Finisar is showing the new QSFP28 eSWDM4 module transmitting live data over 300 meters of OM4 multimode fiber connected to a receiving QSFP28 eSWDM4 module.

At ECOC, Finisar is also showing  a 10G Tunable BiDi Transceiver for Wireless, CATV and Enterprise networks. The demo features multiple tunable Bidi SFP+ modules supporting 40 bidirectional point-to-point links on a
single fiber.

A third ECOC demonstration features a 100G QSFP28 ER4f transceiver supporting 40km 4WDM applications. This transceiver is the newest member of the Finisar suite of extended reach QSFP28 modules. The ER4f module enables 40 km links at 100G data rates over duplex single mode fiber (SMF) with FEC on the host, or 30 km links with duplex SMF without FEC.

Source Photonics and Credo demo Single Lambda 100G at 20km

A new generation of single wavelength 100G trancseivers is a step closer.

Whereas currently deployed 100G optical transceivers rely on 4x25G WDM technology, the next generation of transceivers will use higher order modulation techniques, such as PAM4, and higher data rate operation at 53Gbaud. This means that that one laser and one receiver could do the job that currently requires four lasers and four receivers. In addition to 100G-DR/FR/LR, Source Photonics plans to leverage this technology for 400G-DR4/FR4.

At this week's ECOC 2017 in Sweden, Source Photonics will be hosting a private demonstration of its internally packaged TOSA and ROSA sub-assemblies in an optical loopback configuration through 20km of single-mode fiber using a single 100G channel of Credo’s low power PAM4 IC technology.

Source Photonics said its testing revealed that the bit-error-rate (BER) after 20km of fiber remains better than the KP4 FEC requirement and was around 5x10-5. The TOSA is based on Source Photonics’ EML laser technology which provides the necessary bandwidth to achieve a TDECQ value below 2.5dB. The room temperature link budget of 10dB provides considerable margin for the most significant link specifications under development in the industry, allowing production margin for performance variations.

“We are continuing to invest in next generation technology, such as Single Lambda 100G, as part of our commitment to providing leading edge solutions for data centers,” said Manish Mehta, EVP, PLM Source Photonics

Spirent also announced it had partnered with the China Mobile Research Institute (CMRI) to demonstrate automated testing of virtual core networks.

100 Gbit/s switch testing

The test, completed by Spirent and the New H3C Group and moderated by independent test lab Network Test, demonstrated the line-rate forwarding capacity and hyper-scale IP route announcement capacity of the H3C S12500X-AF chassis loaded with 100 Gbit/s ports and achieving a density of 768 x 100G ports per chassis. The S12500X-AF switch can support 48 x 100 Gbit/s QSFP28 pluggable optical modules per slot.

The test involved Spirent TestCenter and the N11U chassis, representing Spirent's flagship network performance test solution, equipped with the high density dX3 12-port 100 Gbit/s test modules designed to verify next-generation data centre architectures and routers.

For the testing, Spirent TestCenter generated 100 Gbit/s line-rate transaction traffic of various frame lengths and provided packet loss, latency, jitter, frame sequence, code errors and FCS error analytics to reflect the quality of transmission in real time.

The Spirent dX3 quint-speed test module can support twelve 100 or 40 Gbit/s ports per slot, 25 x 50 Gbit/s ports, or 48 x 25/10 Gbit/s ports per slot. It also supports key interface features such as FEC, auto-negotiation and Link Training. The module can be used to verify data plane QoS for hyper-dense network devices at line-rate, and for testing complex routing, data centre and access protocols on switches and routers.

Virtual core network testing

Separately Spirent announced a collaboration with the China Mobile Research Institute (CMRI) to demonstrate automated testing of virtual core networks at Mobile World Congress (MWC) Shanghai. Spirent noted that the demonstration is part of a joint effort to develop a methodology for automated testing of the functionality and performance of the China Mobile TIC (Telecom Infrastructure Cloud).

The partners plans to incorporate the test methodology into an automated testing system developed by CMRI to speed testing of services in operational virtual core networks and to form part of the complete vEPC environment developed by CMRI.

At MWC, Spirent has provided the test engines for the demonstration, including the virtualised mobile core network emulation and performance testing tool, Landslide Virtual, and the automated testing platform, iTest. The solutions automate performance and functionality tests used to develop, spin-up and monitor the vEPC. In addition, devops models have been developed for the test methodologies, allowing tests to be automated and incorporated into the virtualised network.

China Telecom launches 100G Asia-Europe on Terrestrial Route

Hong Kong-based China Telecom Global (CTG), the subsidiary of China Telecom established in 2012, announced the launch of 100 Gbit/s service capability over its terrestrial cable system to address demand for high capacity connectivity between Asia and Europe in collaboration with Russian operators.

Building on the launch of the Super TSR (Transit Silk Road), an ultra-low latency terrestrial route via the China-Kazakhstan Gateway, the latest initiative further diversifies CTG's product portfolio across the Europe-Asia route.

CTG's new 100 Gbit/s capability is supported by cross-border transmission systems leveraging the China-Russia, China-Mongolia-Russia and China-Kazakhstan-Russia routes. The solution will be managed in collaboration with Russian partners, with which CTG has established a long-term strategic relationship.

CTG stated that the service launch represents the first terrestrial 100 Gbit/s bandwidth option available between Asia and Europe, and is intended to support increasing IP transit/transmission demand from carrier partners and IP service providers.

CTG launched the Super TSR last year, offering latency performance of 147 ms from Shanghai to Frankfurt, Germany and 159 ms between Hong Kong and Frankfurt, which is claimed to be 10 ms lower latency than on existing routes. The new shorter route was implemented in partnership with a Kazakhstan operator. CTG noted that the developments are part of its efforts to support China's Belt and Road initiative.

  • Previously, last December CTG and Nepal Telecom announced an agreement to deliver IP services in Nepal leveraging the newly launched terrestrial route connecting China and Nepal, via Jilong (Rasuwa) Gateway.

Mellanox 100G Milestone: 100,000 Direct Attach Cables Shipped

Mellanox Technologies reached a significant milestone:  more than 100,000 units of its Direct Attach Copper Cables (DACs) have now been shipped to serve the growing demand of hyperscale Web 2.0 and cloud 100Gb/s networks.

“Hyperscale customers are selecting Mellanox cables due to our advanced manufacturing automation technologies which enable us to achieve higher quality, lower costs and to deliver in high volume,” said Amir Prescher, senior vice president of business development and general manager of the interconnect business at Mellanox. “Copper cables are the most cost effective way to connect new 25G and 50G servers to TOR switches as they enable the entire new generation of 100Gb/s networks.”

Mellanox offers a full line of 10, 25, 40, 50 and 100 Gbps copper cabling for server and storage interconnect. The two most popular options are splitter cables, which feature a 100 Gbps connector at one end for plugging into a switch port and either two 50 Gbps connectors or four 25 Gbps connectors at the other end for connecting to 25G or 50G servers. Widely used by hyperscale customers to connect servers to the top of the rack (TOR) switch, DACs have lower cost and zero power consumption when compared to optical cables and transceivers. The superior performance and low 1E-15 BER eliminates the need for FEC, which would add latency to the critical server-TOR link.
