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.

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:



(1)




(2)




(3)

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:




(4)

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:



(5)



(6)

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

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.

OIF Launches 100G Serial Electrical Links

The Optical Internetworking Forum (OIF) has begun work on a 100G Serial Electrical Link project.

The very short reach (VSR) CEI-112G chip-to-module interface project will support a nominal lane rate of 112 Gb/s, enabling narrower interfaces to optical modules and is expected to be more energy efficient than previous interfaces. The CEI-112G-VSR specification doubles data rates over the current generation CEI-56G-VSR interfaces.

The OIF said this work will be followed by both shorter and longer reach projects.

“As bandwidth increases, electrical interfaces need to reflect that trend. Given the lead times, development of standards for the next generation of electrical links needs to start now,” said David Stauffer of Kandou Bus and the OIF’s Physical and Link Layer Working Group Chair and board member. “The OIF is continuing its roadmap for 100 Gb/s thru 400 Gb/s and beyond applications, addressing multiple reaches for chip-to-chip and chip-to module interfaces.”
