The debut of Cisco’s CRS-3 router may have scored high on this week’s hype-o-meter, but now rival Juniper Networks is making some core routing noise of its own. TeliaSonera is leveraging Juniper’s TX Matrix Plus, the multichassis version its T1600 core router.
And like most incumbent service providers, TeliaSonera has two sources on hand for its core routing needs: Cisco and Juniper. In 2007, TeliaSonera also deployed the CRS-1. For this deployment, Juniper is not replacing its rival, but instead is upgrading an existing T-Series router in its Frankfurt, Germany node to the TX Matrix Plus.
According to a LightReading article, Juniper says this deployment is part of an ongoing series of network upgrades that it has lined up with TeliaSonera. “It’s not the last one. We’re working with them on a number of upgrades,” says Esben Dahl-Nielsen, a regional sales director at Juniper.

Verizon is serious about 100 Gbps networking, and its latest field trial in North Dallas, Texas is another proof point in the service provider’s desire. In the latest trial, Verizon worked with Juniper Networks, NEC Corporation of America, and Finisar Corp. to apply standards-based optics end-to-end and 100 Gbps native router interfaces.
Following a deployment of a 100 Gbps link between Paris and Frankfurt, Germany that it implemented in December, Verizon transmitted data over a 1,520-km optically amplified section of its network in North Dallas for this trial. One of the bigger implications of the trial is that it is being used to validate the 100 Gbps transfer rate standard set to be ratified by the IEEE and ITU-T this June.
During the trial, Verizon demonstrated end-to-end traffic flow, including live video traffic through a 100 Gbps interface on the Juniper T1600 Core Router to the NEC SpectralWave DWDM system, which was equipped with 100G real-time coherent transponders. Verizon then made a connection between the router and the DWDM system through Finisar 100G CFP optical transceiver modules.
Instead of migrating to 40 Gbps, it’s clear that the larger service providers are set on taking a detour directly from 10 Gbps to 100 Gbps–a process that Verizon argues is less costly than upgrading its networks with more 10 Gbps links. Since 2007, Verizon has been conducting various live 100 Gbps trials on its network. And while it has not set specific timelines yet, the service provider told FierceTelecom in a previous interview about its European 100 Gbps deployment that it plans to upgrade other 10 Gbps showing signs of exhaustion to 100 Gbps in the U.S.

We’ve got a lot going on here on the wireline side of FierceTelecom this week. In addition to the launch of our new FierceCable newsletter, I would like to call your attention to our new eBook on packet optical networking platforms (PONP).
As you’ll see when you read the PONP eBook, the movement to PONPs reflects the incumbent carriers challenge of maintaining legacy and next-gen service demands.
These factors are driving service providers to adopt platforms that can support the roles of optical transport, TDM and packet services. A Packet Optical Network Platform (PONP) serves those roles by combining three essential elements: a WDM piece with a reconfigurable add-drop module (ROADM); a TDM interface to multiplex and groom traditional TDM traffic; and an Ethernet switching interface. Of course, vendors and service providers alike are divided on what’s the best PONP approach.
Router vendors such as Juniper favor an approach that integrates optical transponders and OTN switching to a core router, while optical-centric vendors (Fujitsu and Cyan Optics) favor a ‘packet integration approach’ that adds OTN and packet switching to the optical network platform.
Another question with PONPs is why a next-gen platform should support old school TDM when IP is clearly the future? Well, as we chronicle in a case study on Verizon Communications’ application of PONPs in its network, the ability to support TDM and packet helps it meet the varying demands of its wholesale wireless backhaul and even enterprise customers.
One area where TDM continues to be prevalent for Verizon is in wireless backhaul. In a case study we conducted with Verizon, Glenn Wellbrock, director of optical transport network design and architecture for Verizon explains that the majority of Ethernet continues to traverse over SONET.
For Verizon, the PONP comes in handy as a way to accommodate the varying requirements its wireless carrier customers have for wireless backhaul on one network element. Today, wireless operators favor three different approaches: all-Ethernet point to point transport, switching in between and DS1 transport.
“So for us, the transition is slow, and we can see all three service types at every cell tower,” says Wellbrock. “Everyone has different ways they want to carry this Ethernet handoff, even though it may all be Ethernet.”
What Verizon’s experience reveals is that regardless of any vendor debate over what approach is best, the application of this technology will be ultimately decided by the needs of the carrier and one that provides a bridge between the old TDM and next-gen IP worlds.
With that in mind, I encourage you to take a look at the eBook and weigh in on the debate on what’s becoming a transformational trend in the telecom industry. –Sean

Strong sales of IP edge routers helped drive worldwide revenue of routers and switches 17 percent in Q4 09. However compelling the fourth quarter was, it could not prevent a 12 percent decline to $11.1 billion for the year.
Not surprisingly, the ongoing decline in sales of multiservice ATM switches–a segment that has continued to decline for multiple quarters–was a major contributor to the downward trend.
In 2009 there were various positional shifts amongst the router/switch vendors. Cisco and Juniper may have continued to lead the market, but their market share dropped from 69 percent in 2008 to 59 percent in 2009, while Alcatel-Lucent and Huawei increased share. At the same time, Tellabs’s focus on the wireless sector enabled it to beat out Ericsson and be listed on the top five switching/routing vendor segments for the first time.
“All six of the top router vendors posted strong double-digit revenue increases in the fourth quarter, and we expect modest growth in the router segment to continue in 2010 as carriers carry out fixed-mobile convergence strategies for their router networks,” said Michael Howard, co-founder and principal analyst for carrier and data center networks at Infonetics Research in a release.
On the regional front, Asia Pacific stood out with 19 percent year-over-year growth in IP edge and core router revenue. Infonetics attributes growth in Asia-Pacific to the Chinese government’s aggressive telecom stimulus and reorganization of its top service providers.

Let the core routing upgrade wars begin.
Entering the core routing networking ring is Juniper with a new capability that will enable customers to upgrade their existing T-Series routing gear to support 250 Gbps full duplex slot capacity. Leveraging a new in-house chipset design, Juniper says the upgrade will be able to deliver 4 Tbps of capacity in a half-rack system.
Available for purchase early next year, the proposed upgrade is likely the first attack on Cisco’s proposed MSC 120 core router that claims to support 120 Gbps per-slot. It would also surpass core networking platforms from both Alcatel-Lucent and Huawei–who have advertised support for 100 Gbps per-slot capacity.

It’s almost like clockwork. Once word leaked earlier this week that Cisco is prepping an upgrade to its CRS-1 core router to take it to 120G per slot, Juniper this week said it has a new generation of silicon to take its T series core routers to 250G per slot, full duplex. Read more

Fresh with a major customer win from Qwest Communications, Alcatel-Lucent has now unveiled a new converged IP/Optical backbone network solution that it says will help service providers keep up with the insatiable demand for Internet-based video and high-speed business services (tele-medicine and video surveillance). Alcatel-Lucent thinks that instead of just slapping in a new core router–a costly exercise–service providers should leverage a converged IP/Optical backbone that integrates IP and optical transport. With this converged approach, Alcatel-Lucent claims they can save service providers 30 percent in Capex costs in addition to lower power, space and operational costs.
An integrated control plane between the optical and IP layers is a key component to Alcatel-Lucent’s strategy. By taking this approach, the solution can improve service provisioning time as well as increase network capacity with support for 40 and 100 Gbps data plane speeds. In addition, Alcatel-Lucent will offer an integrated network management approach that will provide network visibility across both the IP and optical domains to a carrier’s designated Network Operation Centers (NOCs.)
While other packet optical network service players including Cisco, Ciena, Fujitsu and Juniper will likely downplay Alcatel-Lucent’s approach, having a major customer endorsement from Qwest gives Alcatel-Lucent an initial proof point for the new offering.
