What Would You Do With a 92 TBps Router?
enodev writes "Cisco announces today it's new 'Carrier routing system' For a price tag starting at $450,000 it's able to route up to 92 Tbps. It also features IOS-XR and the first optical OC-768c/STM-256c optical Interface." update changed TBps to Tbps and suddenly things seemed less cool ;)
"Juniper Networks has individual routers that are at least as fast, but the company cannot combine as many routers to ultimately produce the same speeds, according to Chris Nicoll, a telecommunications industry analyst with Current Analysis, a research firm."
and more....
"The new router design is the first developed by Cisco that allows several routers to be connected, according to the company. A single router would be able to transmit data at 1.2 terabits a second. But as many as 72 routers can be hooked together to send data at 92 terabits a second, far faster than any router sold now. In telecommunications, data transfer is usually measured in bits per second. A terabit is one trillion bits. "
Hmmm.
It's a small point, but the article calls it 92 Tbps, not 92 TBps. Which means its really 19 terabytes per second, which works out to some ungodly number of libraries of congress per fortnight. Either way, it's a lot.
Terabits/sec (Tbps), not Terabytes/sec (TBps).
I'm not surprised some moron doesn't know his units, especially when it's mentioned in the article and placed in its proper notation. I'm surprised the EDITORS refuse to change it to be factual.

Did you bother to even look at the site? Nooo of course not. From the site:
The Cisco CRS-1 is powered by Cisco IOS XR Software, a unique self-healing and self-defending operating system designed for always-on operation while scaling system capacity up to 92 Tbps.
Click on "Cisco IOS XR" and you get:
Q. What is Cisco IOS XR Software?
A. Cisco IOS XR Software is the newest member of the Cisco IOS Software Family. Cisco IOS XR has been developed to address the requirements for scale, availability, and service flexibility which arise from the creation of converged packet infrastructures that consolidate voice, video, and data services. Cisco IOS XR Software has been specifically optimized to take advantage of the massively distributed processing capabilities of the Cisco CRS-1 Carrier Routing System.
Why do you even bother posting? I wouldn't think it's for karma whoring - such a low UID isn't likely to partake in such things unless adicted. It certainly isn't to contribute quality material to the discussion, either.

You can be sure it will actually be STM-256c as opposed to plain vanilla STM-256.
Almost NO datacomms equipment manufacturers support the non-concatenated versions of SDH above STM-1. I have bitten in the past by companies that said they support STM-4 when they actually meant STM-4c. And of course at the time the telcos only support STM-4 and NOT STM-4c.
I suspect that the STM-256 support will be the same.
(For the uninitiated STM-4 is a straight multiplexing of 4 STM-1s, each with their own header and payload sections. STM-4c is essentially one big STM channel with a single header section and a single concatenated payload section. STM-256c just extends this principle to more insane capacities).
QNX Powers Universal Media Gateway for Next-Generation Digital Video Networks
QNX Software Systems today announced that the QNX® Neutrino® realtime operating system (RTOS) will be shipping as part of the Cisco uMG9850 QAM Module, a new quadrature amplitude modulation product designed to let cable operators use Gigabit Ethernet to deliver video-on-demand and other multimedia services efficiently and cost-effectively to TV set-top receivers.
'Little OS that could' just might
"In a deal signed two years ago, Cisco (csco) chose QNX as its preferred real-time OS vendor as part of Cisco's 'ongoing efforts to increase the reliability and availability of data-voice-video networks.' Since then, not much seems to have materialized from the partnership."
Cisco's HFR is here
"The IOS-XR operating system kernel was acquired from QNX Software Systems, a small Canadian developer of realtime operating system code to companies in the automotive, communications, defense, industrial automation and medical device markets. Cisco already ships QNX operating system code in its uMG9850 QAM digital video module for the Catalyst 4500 Gigabit Ethernet switch."
Cisco Unveils the HFR
" The transition is analagous to Microsoft Corp. (Nasdaq: MSFT - message board) moving from DOS-based operating systems to Windows NT, says analyst Stephen Kamman of CIBC World Markets.
Just as NT did, IOS XR could begin trickling down to lower-level systems, eventually permeating Cisco's entire portfolio, including edge and enterprise boxes. "The question is how quickly they can push that software through the product line," Kamman says."
"The software is based on a kernel licensed from QNX Software Systems, but tailored for the job. 'We have made some pretty substantial modifications to [the QNX code] that are Cisco proprietary,' Volpi says."
