Juniper Claims 100-Gig First

Juniper Networks Inc. (NYSE: JNPR) is announcing what it claims will be the first available 100-Gbit/s Ethernet interface for a router, targeting the kinds of requirements Verizon Communications Inc. (NYSE: VZ) has been talking about.

In fact, Verizon features prominently Juniper's press release: The carrier has been pining for a more efficient -- and cheaper -- way to deal with the multiple 10-Gbit/s Ethernet lines that populate its network. (See LR Live: Verizon Plots 100 GigE RFP and Verizon's Wellbrock: 100G Is Needed.)

Verizon has "a strong desire to bring 100-Gbit/s technology into the network primarily to simplify the topologies," says Luc Ceuppens, senior director of marketing at Juniper. "They have a lot of 10 Gbit/s now and can eliminate a lot of those links."

Juniper's 100-Gbit/s interface is going on the T1600 core router and is housed in a standard CFP module. It's intended, not for metro or long-haul reaches, but for the box-to-box connections within a data center or central office.

The T1600 can run 100 Gbit/s per slot without oversubscription, and its switch fabric has the capacity to operate without oversubscription even if all eight slots run 100-Gbit/s interfaces, Ceuppens says.

Last year, Cisco Systems Inc. (Nasdaq: CSCO) announced a demo of a 100-Gbit/s interface for its CRS-1 core router. (See Comcast, Cisco Test 100-Gig.)

Juniper might be faster to market, though, as it expects the T1600's 100-Gbit/s ports to go into customer trials later this year.

Verizon is targeting a 2010 deployment for 100-Gbit/s technology.

Companies including Ciena Corp. (NYSE: CIEN) and Nortel Networks Ltd. have begun toying with the idea of pure 100-Gbit/s feeds. But carriers are saying they really need a 100-Gbit/s wavelength as a carrying vehicle for multiple 10-Gbit/s feeds, Ceuppens says. "They need to eliminate some of the inefficiencies of link aggregation." (See Ciena Sending 100GE Live and Nortel Shows Single-Slice 100GE.)

Of course, some vendors still like the link aggregation approach, especially for transmitting data across longer distances. Brocade Communications Systems Inc. (Nasdaq: BRCD), now the owner of Foundry Network, talks about packing 32 10-Gbit/s Ethernet links onto one fiber. (See Foundry LAGs Ahead and Brocade Takes Aim at Cisco (& Juniper).)

The cost of the 100-Gbit/s link is going to be "just under" that of ten 10-Gbit/s links at first, Ceuppens says. How quickly that price drops will depend on component availability. Still, that's an improvement over 40-Gbit/s Ethernet, where the price remains higher than that of four 10-Gbit/s links, he says.

re: Juniper Claims 100-Gig First

I have been following up on 100G progress, wondering whether users will adopt 40G or 100G instead. True that 100G have been getting a lot of momentum recently. First, with EXOF and IXIA announcing test gears for 100G CFP and now Juniper demosntrating to Verizon.


Let's hope they can keep up.

re: Juniper Claims 100-Gig First

I think it depends on if users choose Ethernet or SONET/SDH.  Ethernet works at 10G, 100G, etc, and SONET/SDH works at 10G, 40G, 160G, etc.

re: Juniper Claims 100-Gig First

Did I miss something where is the technical explanation for how they did 100G?

re: Juniper Claims 100-Gig First

They haven't. Who has seen it? Who would buy it today? Who has seen test gear that can actually prove it? Please correct me.


If Juniper was smart... they would listen to the Federal/Intel community and discuss transport mechanisms other than Ethernet and IP.

re: Juniper Claims 100-Gig First Just to update everyone on a few things regarding the state of 100GE:


(1) 100GE test equipment has existed for nearly 1 year through Ixia: http://www.ixiacom.com/solutio...



(2) Xilinx demonstrated in hardware (with no cheating!) the first commercially available single FPGA 100GE solution with our partners Netlogic, Sarance, Avago and Ixia at OFC in late March 2009:
http://press.xilinx.com/phoeni...



(3) You can learn more about hardware-proven, low risk solutions for 100GE from Xilinx on both our production Virtex-5 TXT and now-sampling Virtex-6 FPGAs on our website here:

Lots of hard work from many people, but it was a hoot.

re: Juniper Claims 100-Gig First

... This was in response to "Juniper Claims 100GE first" but since you decided to market yourself here:


1.) Key statement here: "As the IEEE P802.3ba standard moves toward finalization in 2010" (MAYBE).... Who's buying pre-standard technology today?  How will more than 50% of the existing fiber in the carrier world support this today? Who's making the optics to support this?


2.) What third party can verify this claim? "Xilinx demonstrated in hardware (with no cheating!) the first commercially available single FPGA 100GE solution with our partners Netlogic, Sarance, Avago and Ixia at OFC in late March 2009." The fact that you say "in hardware" means thats it's half baked.

It's the path of any cutting-edge technology.


Even after the standards are ratified, it takes a long way before equipment from different vendors can de-facto interoperate.


So kudos to Juniper for making the first packet processing unit with 100GE optics.


Now the real question - how cheaper it is compared to 10x10GE bundle?


If there is significant saving from buying 100GE interface over 10x10GE, it will sell even if it works only between Juniper devices (T-series is the de-facto standard core router nowadays). 


I am also pretty sure that Juniper will factor some protection policy for early adopters. Judging from impact of 10GE, i can't tell enough on how important the 100GE is to the industry... hope Juniper can drive the cost down quickly.

Dear Idafmool:


 


You commented:

The 100GbE test gear from IXIA and EXFO has already been announced and shown in live events such as Interop.


 


Chip providers like Netlogic, Xilinx and others have already announced products.


 


100G optical modules were demonstrated at OFC in 2009. MSA is formed and prototypes are shipping.

re: Juniper Claims 100-Gig First

This is a client-side solution that runs over 10Km installed SMF.


The basic question is this: Are you doubting whether there is a market for 100G starting in Mid 2010?


 


Camil

re: Juniper Claims 100-Gig First I think you and I know that showing gear at events like Interop is a LONG way from functioning products and customers actually buying it. Getting to the real questions, and basis for my comment - which no one has chosen to answer yet... who's buying it? What fiber can support it?
