Verizon Likes Cisco's CRS-3

Verizon Communications Inc. (NYSE: VZ) announced Tuesday that it's going to use the Cisco Systems Inc. (Nasdaq: CSCO) CRS-3 core router, with deployments starting during the first half of 2012.

The routers will be used in certain U.S. markets including Atlanta, Boston, Chicago, Dallas, Los Angeles, New York and Seattle, Verizon's release says. The motivation is to add 100Gbit/s to the core of the FiOS network and possibly to edge networks as well.

Why this matters
Verizon already uses the CRS-1; in fact, at one point in 2009, Verizon was the largest CRS-1 customer. So, in that sense, this isn't a surprise. (See Cisco Lands Verizon.)

But Verizon also uses core routers from Juniper Networks Inc. (NYSE: JNPR). In fact, Juniper has been the router star in Verizon's 100Gbit/s trials and deployments so far, including a buildout in the United States. So, this announcement means Cisco at least gets to put its name on a Verizon 100Gbit/s announcement, too.

But is Cisco nudging into Juniper's piece of Verizon? It's not so far-fetched; a year ago, Juniper may have won a deal in the opposite direction. Juniper's core-router sales for the fourth quarter of 2010 were up 48 percent compared with the previous quarter, possibly driven by "a competitive win at Verizon (vis-à-vis Cisco) for a piece of the RBOC’s private IP backbone," analyst George Notter of Jefferies & Co. Inc. wrote at the time.

In any event, both vendors seem to have secured their spots in Verizon's 100Gbit/s plans.

re: Verizon Likes Cisco's CRS-3

Some details, via their PR firm, about the company's use of CRS-1s and CRS-3s:


"We use the CRS1 in the Verizon Public IP network as a high speed access gateway router. We also terminate 10G customers. These are being upgraded to the CRS3 to support 100G access and uplinks to the backbone. Also, we use the CRS1 in an aggregation role in our FiOS network. Those routers will be upgraded to CRS3 to support 100G uplinks to the backbone. Verizon Wireless is also upgrading some of its CRS1 infrastructure to CRS3 to facilitate 100G requirements."

Yes, it sounds like the CRS3s are being used purely as CRS-1 upgrades.  Although I really do think (& found at least one person who agrees) that it's the Juniper core routers that inhabit Verizon's public-IP core.


So, I'm still left wondering a little. But for the moment, I can buy the story that the CRS-3, like the CRS-1 before it, is being used as a big-pipe uplink to the backbone, especially for 100G.
