Infonetics: Record Year for GPON in China; VDSL Shipments Outstrip ADSL

For the full year 2013, worldwide broadband aggregation equipment revenue totaled $6.96 billion, a 1.6% increase over 2012, according to a new report from Infonetics Research.

Some key highlights of the report:

  • For the full year 2013, worldwide broadband aggregation equipment revenue totaled $6.96 billion, a 1.6% increase over 2012
  • 2013 capped a record year for GPON in China, with revenue increasing 64% from the previous year as China Unicom and China Telecom continued deployments of GPON-based FTTH
  • VDSL shipments surpassed ADSL for the first time in 2013 and now make up over half of all DSL ports shipped, though this was not enough to lift overall DSL aggregation market on a year-over-year basis
  • The top 3 overall broadband aggregation revenue leaders are once again Huawei, Alcatel-Lucent, and ZTE

“2013 ended up being a strong year for fixed broadband spending, driven by the continued growth of GPON and vectoring-capable VDSL gear. Competition, over-the-top (OTT) and multiscreen video, and national broadband goals remain the primary drivers for fixed broadband investment,” notes Jeff Heynen, principal analyst for broadband access and pay TV at Infonetics Research.

Fujitsu Selected for FTTH in New Mexico

Fujitsu Network Communications was selected by Kit Carson Electric Cooperative (KCEC) to implement a new Fiber-To-The-Home (FTTH) project in northern New Mexico’s rural, underserved counties of Taos, Colfax, and Rio Arriba.

KCEC has access to $64 million in funding from the U.S. Rural Utilities Service to help drive economic development by providing opportunities for high-bandwidth broadband connectivity to businesses, households, community institutions and two Native American Pueblos. The network will also lay the groundwork for KCEC’s planned Smart Grid, which will feature an advanced metering infrastructure and real-time detection of power outages to promote energy efficiency and offer customers higher levels of service.

Fujitsu said its design will future-proof the co-op’s investment in the network and enable delivery of additional services by using a combination of Ethernet and Gigabit Passive Optical Networks (GPON). An Ethernet-based core infrastructure connects the electrical power substations and GPON is used in the access networks to deliver 100 Mbps in broadband connectivity to residents and 1 Gbps to schools, hospitals and government agencies. At KCEC’s request then, Fujitsu designed and engineered a new infrastructure and took on the role of network systems integrator as well as responsibility for overall program management.

“Fujitsu’s understanding of the best-of-breed technologies and the implementation strategy made them an invaluable partner,” said Luis Reyes, Chief Executive Officer and General Manager of Kit Carson Electric Cooperative. “Their vendor-agnostic approach, ability to integrate networking technology solutions from multiple manufacturers, and proven program management methodology are vital to our project’s success. Together, KCEC and Fujitsu are building a broadband infrastructure that will provide the foundation necessary to drive economic growth, create stronger communities, improve educational opportunities, and give citizens better access to healthcare.”

AT&T Completes Cricket Acquisition

AT&T completed its previously announced acquisition of prepaid wireless provider Leap Wireless International Inc., which operates under the Cricket brand, for $15 per share in cash. Leap shareholders will also receive a contingent right entitling them to the net proceeds received on the sale of Leap’s 700 MHz “A Block” spectrum in Chicago, which Leap purchased for $204 million in August 2012.

Leap currently operates a 3G CDMA network, as well as a 4G LTE network covering 21 million people across 35 states. The company serves about 5 million prepaid mobile users under the Cricket brand. It currently ranks as the fifth largest mobile operator in the U.S. Its network currently covers approximately 97 million people in 35 U.S. states, and Cricket had 4.57 million customers as of February 28, 2014. Customer migrations are expected to be completed approximately 18 months after the launch of the new Cricket.

The deal would include all of Leap’s stock and wireless properties, including licenses, network assets, retail stores and approximately 5 million subscribers. As of April 15, 2013, Leap had $2.8 billion of net debt. Leap shareholders will also receive a contingent right entitling them to the net proceeds received on the sale of Leap’s 700 Mhz “A Block” spectrum in Chicago, which Leap purchased for $204 million in August 2012.

AT& said it plans to integrate Cricket with its existing operations to create the "new Cricket" for the pre-paid market -- featuring a combination of simple, low-cost rate plans and smartphones.

In addition to Cricket’s operations, AT&T also acquired spectrum in the PCS and AWS bands covering nearly 138 million people. This spectrum is largely complementary to AT&T’s existing spectrum holdings and includes unutilized spectrum covering 41 million people. AT&T will immediately begin to put the unutilized spectrum to use to support 4G LTE services for its customers. This additional spectrum will provide additional capacity and enhance network performance for customers using smartphones and other mobile Internet devices.

Crehan Research: 10GbE Data Center Switches Surpass 1GbE

Robust 2013 year-end growth has propelled 10 gigabit Ethernet (10GbE) data center switch port shipments past those of gigabit Ethernet (1GbE) for the first time, according to a recent report from Crehan Research.

Since first product introductions in 2001, 10GbE data center switching has overcome numerous hurdles on the path to majority adoption. These have included:

  • Very low port-density switches, with accompanying prices prohibitive to volume data center deployments. 
  • High-priced optical pluggable modules accompanied by many different multi-source agreements and form-factors, with the market cycling through the 300pin, XENPAK, XPAK, XFP and X2 modules before finally settling at the current dominant SFP+ form-factor. 
  • Limited default or free 10GbE networking on volume rack servers to seed the market for a switch upgrade, similar to what happened with 1GbE. 
  • Slower-than-expected arrival of compelling 10GBASE-T solutions. 
  • Two major recessions in the aftermath of the housing and dot-com bubbles. 

“When I first saw 10 gigabit Ethernet switches arrive on the market back in 2001, I never thought that we would be well into the next decade before these products would comprise a majority of data center Ethernet port shipments,” said Seamus Crehan, president of Crehan Research. “Despite a network traffic growth curve that turned out to be way above most expectations, this technology was encumbered by numerous obstacles on its way to becoming a majority of data center connections,” he added.

Blueprint: SDN and the Future of Carrier Networks

by Dave Jameson, Principal Architect, Fujitsu Network Communications

The world has seen rapid changes in technology in the last ten to twenty years that are historically unparalleled, particularly as it relates to mobile communications. As an example, in 1995 there were approximately 5 million cell phone subscribers in the US, less than 2 percent of the population. By 2012, according to CTIA, there were more than 326 million subscribers.  Of those, more than 123 million were smartphones. This paradigm shift has taken information from fixed devices, such as desktop computers, and made it available just about anywhere. With information being available anywhere in the hands of the individual users some have started to called this the "human centric network," as network demands are being driven by these individual, often mobile, users.

But this growth has also created greater bandwidth demands and in turn has taken its toll on the infrastructure that supports it. To meet these demands we’ve seen innovative approaches to extracting the most benefit from existing resources, extending their capabilities in real-time as needed.  Clouds, clusters and virtual machines are all forms of elastic compute platforms that have been used to support the ever growing human centric network.

But how does this virtualization of resources in the datacenter relate to SDN in the telecom carrier's network? Specifically how does SDN, designed for virtual orchestration of disparate computational resources, apply to transport networks? I would suggest that SDN is not only applicable to transport networks but a necessary requirement.

What is SDN?

The core concept behind SDN is that it decouples the control layer from the data layer. The control layer is the layer of the network that manages the network devices by means of signaling. The data layer, of course, is the layer where the actual traffic flows. By separating the two the control layer can use a different distribution model than the data layer.

The real power of SDN can be summed up in a single word - abstraction.  Instead of sending specific code to network devices, machines can talk to the controllers in generalized terms. And there are applications that run on top of the SDN network controller.

As seen in Figure 1 applications can be written and plugged-in to the SDN network controller. Using an interface, such as REST, the applications can make requests from the SDN controller, which will return the results. The controller understands the construct of the network and can communicate requests down to the various network elements that are connected to it.

The southbound interface handles all of the communications with the network elements themselves. The type of southbound interface can take one of two forms. The first is a system which creates a more programmable network. That is to say that instead of just sending commands to the devices to tell them what to do SDN can actually reprogram the device to function differently.

The second type of southbound interface is a more traditional type that uses existing communication protocols to manage devices that are currently being deployed with TL1 and SNMP interfaces.
SDN has the ability to control disparate technologies, not just equipment from multiple vendors.

Networks are, of course, comprised of different devices to manage specific segments of the network. As seen in Figure 2 a wireless carrier will have wireless transmission equipment (including small cell fronthaul) with transport equipment to backhaul traffic to the data center. In the data center there will be routers, switches, servers and other devices.


Today at best these are under "swivel chair management" and at worst have multiple NOCs managing their respective segment. Not only does this add OpEx in terms of cost for staffing and equipment but additionally makes provisioning difficult and time consuming as each network section must, in a coordinated fashion, provision their part.

In an SDN architecture there is a layer that can sit above the controller layer called the orchestration layer and its job is to talk to multiple controllers.

Why do carriers need SDN?

As an example of how SDN can greatly simplify the provisioning of the network let's take a look at what it would take to modify the bandwidth shown in Figure 2. If there is an existing 100MB Ethernet connection from the data center to the fronthaul and it is decided that the connection needs to be 150MB, a coordinated effort needs to be put in place. One team must increase the bandwidth settings of the small cells, the transport team must increase bandwidth on the NEs, and routers and switches in the data center must be configured by yet another team.

Such adds, moves, and changes are time consuming in an ever changing world where dynamic bandwidth needs are no longer a negotiable item. What is truly needed is the ability to respond to this demand in a real time fashion where the bandwidth can be provisioned by one individual using the power of abstraction. The infrastructure must be enabled to move at a pace that is closer to the one click world we live in and SDN provides the framework required to do so.

SDN Applications

No discussion of SDN would be complete without examining the capabilities that SDN can bring through the mechanism of applications. There are many applications that can be used in an SDN network. Figure 4 shows a list of examples of applications and is broken down based on the type of application. This list is by no means meant to be exhaustive.


One example of an application that specifically applies to carrier networks is path computation or end to end provisioning. Over the years there have been many methods that have sought to provide a path computation engine (PCE), including embedding the PCE into the NEs, intermingling the control and data layers. But since the hardware on the NEs is limited, so the scale of the domain it manages is also limited. SDN overcomes this issue by the very nature of the hardware it runs on, specifically a server. Should the server become unable to manage the network due to size, additional capacity can be added by simply increasing the hardware (e.g. add a blade or hard drive). SDN also addresses the fact that not all systems will share common signaling protocols.  SDN mitigates this issue by not only being able to work with disparate protocols but by being able to manage systems that do not have embedded controllers.

Protection and Restoration

Another application that can be built is for protection and restoration. The PCE can find an alternative path dynamically based on failures in the network. In fact it can even find restoration paths when there are multiple failed links. The system can systematically search for the best possible restoration paths even as new links are added to the existing network. It can search and find the most efficient path as they become available.

SDN and OTN Applications

A prime example of SDN being used to configure services can be seen when it is applied to OTN. OTN is a technology that allows users to densely and efficiently pack different service types into fewer DWDM wavelengths. OTN can greatly benefit the network by optimizing transport but it does add some complexity that can be simplified by the use of SDN.

Network Optimization  

Another area where SDN can improve the utilization is by optimizing the network so that over time, it can make better use of network resources. Again, using the example of OTN, SDN can be used to reroute OTN paths to minimize latencies, reroute OTN paths to prepare for cutovers, and reroute OTN paths based on churn in demand.

NFV

In addition to applications, SDN becomes an enabler of Network Function Virtualization (NFV). NFV allows companies to provide services that currently run on dedicated hardware located on the end user's premises by moving the functionality to the network.

Conclusion

It is time for us to think of our network as being more than just a collection of transport hardware. We need to remember that we are building a human centric network that caters to a mobile generation who think nothing of going shopping while they are riding the bus to work or streaming a movie on the train.

SDN is capable of creating a programmable network by taking both next generation systems and existing infrastructure and making them substantially more dynamic. It does this by taking disparate systems and technologies and bringing them together under a common management system that can utilize them to their full potential. By using abstraction, SDN can simplify the software needed to deliver services and improve both the use of the network and shorten delivery times leading to greater revenue.

Australia's NBN Co Tests Coriant's Terabit Super-channel

Australia's NBN Co has completed a trial of a one Terabit per second (Tbps) super-channel over a 1,066 km fibre optic ring in South East Queensland, Australia using Coriant's innovative FlexiGrid technology on the NBNCo Transit Network, which is a wholesale, open access network.

Coriant said this trial demonstrated a Tbps super-channel transmission in a 369GHz grid over 1,066 km. It showed a greater than 35 percent improvement in spectral efficiency which significantly increases the capacity of the system. The trial also demonstrated the flexible allocation of the super-channel by placing it in three separate locations within the c-band which maximizes use of existing fibre resources. This capability, in conjunction with the improvements in spectral efficiency, provides a maximum theoretical transmission capacity of 13 Tbps on existing hardware and fibre over a distance greater than 1,000 km.

NBN Co's Transit network is built using established optical fibre made available by third party carriers on long term leases and Dense Wavelength Division Multiplexing Equipment that provides connectivity from the access networks, including fibre and wireless, through to points of interconnect with NBN Co's wholesale customers.

The field trial was conducted on NBN Co's network using commercially available hardware and pre-commercial software, over the existing fibre that is currently being integrated into NBN Co's Transit Network.

Gary McLaren, NBN Co's Chief Technology Officer said, "We are pleased with the results of the trial with Coriant over our Transit Network. It highlights how established backbone infrastructure can be upgraded with sophisticated optical and electronic equipment to provide extra capacity for the future needs of the National Broadband Network.
"This proof point highlights that the existing transit network is robust and capable, as we rollout a mixture of Fibre-to-the-node technologies (FTTx) being designed to provide access to voice and broadband services faster, cheaper and more efficiently to Australian homes and businesses no matter their location across the country.
"As high-bandwidth applications and the growth of internet usage drive increased demand for network capacity, the ease of upgrading to higher transmission rates in our Transit Network will enable us to continue to deliver a reliable and high-quality broadband experience for our customers."

Coriant Advances Collaboration with Juniper

Coriant reported further progress in its collaboration with Juniper Networks to create an integrated packet transport network (IPTN).

Recent joint R&D between the two networking innovators resulted in the first multi-vendor line side interworking between router and DWDM system suitable for long haul (LH) transmission. This IPTN solution is a combination of the Coriant hiT 7300 DWDM system, Coriant TransNet planning tool, and TNMS network management system with Juniper Networks MX Series and PTX Series routers.

The companies said their latest interoperability test was carried out on line side interworking of PTX 100G DWDM interfaces with hiT 7300 transponders and line system. The results highlight new use cases in seamless packet optical networks, which now include regeneration of router interfaces and handoff between routers from different vendors, which were not previously attuned on the line side.

"We see this collaboration between Coriant and Juniper as an important step that allows operators to offer reliable and scalable networks for richer services to its end-users by a tighter integration of the IP/MPLS and optical network layers," said Uwe Fischer, Chief Technology Officer at Coriant. "Both companies are highly motivated to create integrated packet network transport solutions to contend with the exponential growth in data and to offer long-term support to our customers from now and well into the future."

The full complement of ODUx switching including ODU-0 grooming with ODU-Flex, Carrier Ethernet and MPLS-TP ensures the most cost-effective and efficient grooming solution for packet and transparent services. All interface cards are designed using the latest in pluggable interface technology: SFP+ for 10G and CFP for 100G, including 100G coherent DWDM. All interfaces support a host of white light and DWDM options.
  • Simplicity: Minimal set of highly flexible interface cards supported with unrestricted OTN and packet switching on every port. This simplifies ordering, sparing and deployment resulting in smoother, simpler and faster roll-outs for customers while minimizing the chances of error.
  • Resiliency: High degree of restoration flexibility by providing restoration coordination across multiple layers. From a physical architecture perspective, this includes redundancy in the switching fabrics, interface modules, power supply and processors, and from the network perspective, the integration of ASON/GMPLS control plane and SDN functions for end-to-end, multilayer capabilities.

Huawei's 400G WDM Prototype Promises 'Faster than Nyquist'

At the OFC 2014 Conference in San Francisco, Huawei introduced a 400G WDM prototype for ultra-long-haul transmission that employs Faster Than Nyquist (FTN) technology to increase the 400G transmission distance beyond 3000 km.

Huawei said its FTN technology breaks the limit of the Nyquist sampling theorem, which defines a maximum transmission speed for a fixed channel bandwidth, by leveraging spectrum compression and signal distortion compensation algorithms.  This enables the FTN technology to achieve long-haul transmission of high baud-rate signals on existing networks (similar to transmitting a large file that has been compressed, which requires less bandwidth than transmitting the original file).

The technology enables two types of 400G WDM solutions based on 100 GHz channel spacing — a short-haul solution and the ultra-long-haul solution unveiled at OFC 2014. The ultra-long-haul solution, which applies to backbone transmission, adopts 2SC-PDM-QPSK modulation and supports a record transmission distance of over 3000 km. The short-haul solution, which applies to metropolitan area network (MAN) transmission, adopts 1SC-PDM-16QAM modulation and allows high-quality 400G transmission over a single carrier wave. Huawei's single-carrier 400G solution was recently tested on EXATEL's live network in Poland.

“Huawei has been investing heavily in the high-speed WDM field. The new FTN technology introduced in the prototype exceeds traditional technological limits to deliver ultra-long-haul 400G transmission, breaking new ground for the 400G industry,” said Jack Wang, President of the Huawei transmission network product line.
