Juniper to Announce 40-Gig Strategy?

Juniper Networks Inc. (Nasdaq: JNPR) is preparing to announce a set of 40-Gbit/s interfaces for its core routers, Light Reading has been told. The move would represent an escalation in the already intense fight between Juniper and Cisco Systems Inc. (Nasdaq: CSCO). Both companies already are shipping 10 Gbit/s interfaces -- heretofore the fastest router interface iteration (see Juniper Wins Monster Router Test).

40-gig interfaces would be a significant leap forward not simply because they are four times faster than their 10-Gbit/s predecessors, but also because they should allow service providers to connect routing equipment directly to high-capacity optical transmission devices in metro or long-haul networks in a way that eliminates the need for expensive multiplexing technology. (Currently, carriers would typically deploy Sonet muxes to combine 10-Gbit/s router traffic into a single stream that can be sent to a 40-Gbit/s port on the metro or long-haul optical device.)

However, there are a couple of big question marks hanging over the announcement. It's unclear when the 40-Gbit/s interfaces might be available, given that 40-Gbit/s silicon is in development but still largely a laboratory proposition for now. This raises the possibility that Juniper will offer higher speeds in the short term by aggregating 10-Gbit/s OC192s, before migrating to "real" 40-Gbit/s interfaces later.

That scenario is lent credence by a VC who claims familiarity with the company's product developments. He says that Juniper will roll out its next router interfaces in two phases: a 20-Gbit/s version, followed by a 40-Gbit/s version "some time down the road." Cisco is expecting the announcement, according to a source at the company who requested anonymity. "We've heard rumors to that effect, but no [Cisco sales personnel have] reported seeing them at customers. Typically, we do see early units in customer labs when a product is in beta."

In the meantime the real battle between Cisco and Juniper is in the market for smaller routers, the source says; "We're in more serious fights with them versus the M20, as we're in the momentum pause of transitioning [customers] from the 7500 to the 7600 and 10000 [Series routers]."

"Sooner or later the major router players will have to roll out 40-gigabit interfaces. It's the next logical step for them," says Menachem Abraham, founder of Mintera Corp., a startup based in Lowell, Mass., that is developing 40-Gbit/s optical subsystems for use in ultralong-haul networks. Abraham says that the Optical Internetworking Forum (OIF) has already set up a committee to develop a 40-gig VSR (very short reach) standard for use in connecting routers and optical transport devices. A draft spec has not yet been completed, however.

Juniper declined to be drawn, on when it will ship 40-gig technology. "We'll tell you when our customers have it," said Carl Showalter, vice president of marketing for the company. He also refused to comment on whether Juniper had 40-Gbit/s products in the works. "I'm not going to comment on that," he said.

re: Juniper to Announce 40-Gig Strategy? We will have a much more detailed story up tomorrow when we know more.

Thank you for your helpful input.

re: Juniper to Announce 40-Gig Strategy? Most of us have been waiting for the announcement of a new product from JNPR. The real question is will it be an extension of the existing family/architecture or an all new architecture.

The rumor is that this new product will initially support 20 Gb per slot not a 20 Gb interface. This means 2 10gigE/oc192. There is no interface for 20 Gb that i am aware of. After Oc192 we go to Oc768. After gig10 it will be gig40 or gig100. I don't believe there will be a 20 Gig ethernet or Oc384 and the concept seems pretty strange coming from a "technology" magazine such as LR.

The rumor continues that this will be followed with a product that supports 40 Gb per slot which would allow the use of 4 10gigE/oc192 interfaces or 1 0c768.

Note that the current JNPR and CSCO product only goes to 10 Gb per slot.

re: Juniper to Announce 40-Gig Strategy? I'm surprised that you are receiving any information at all considering Juniper has repeatly stated they do not announce anything prior to customer deployment.

Are they changing their ways or do you guys just have some reliable inside connections?

re: Juniper to Announce 40-Gig Strategy? the story is better but still inaccurate. JNPR cannot release 40-gig interface for current product. It only has 10-gig per slot and x-slot would probably not be an option.

20 and 40 gig implies a whole new chassis/product. The M320 has been rumored for a while though... it is the sensible progression similar to what they have already done.

re: Juniper to Announce 40-Gig Strategy? "There is no interface for 20 Gb that i am aware of. After Oc192 we go to Oc768."

What I heard is that there is no standard for anything above 10-Gig right now. It seems as though OC-768 should be an evolution of the previous standards, but apparently not everyone is doing it this way. There are also 80-Gig interfaces on the drawing boards and these certainly don't fall into the usual "multiply by 4" pattern.

re: Juniper to Announce 40-Gig Strategy? My understanding is that the OIF has a committee working on a 40-gig VSR (very short reach) standard. But no spec yet.

re: Juniper to Announce 40-Gig Strategy? I agree. We are trying to find out more details.

Do you know anything else about the M320?

re: Juniper to Announce 40-Gig Strategy? steve,
the real news in optical today is not junipers fake marketing pitch around 40G interfaces, but lucent's sale of its lambda router.

where is that news on "light"reading?
Steve Saunders 12/4/2012 | 8:25:56 PM
re: Juniper to Announce 40-Gig Strategy? it's coming. A story is in the works. We agree with you that it is big news.

re: Juniper to Announce 40-Gig Strategy? How come these comments don't show up at the bottom of the article anymore?
