What would you do with 322 Terabits per second?
 In 2004, I spent my Victoria Day holiday near San Jose, Calif. covering the  launch of Cisco Systems Inc.’s Carrier Routing System 1. 


Been there, done that, got the T-Shirt. Literally.


I still have the T-shirt I got from the CRS 1 launch with the slogan, “What would you do with 92 Terabits per second?” As far as vendor T-shirts goes, this one stood up quite well. But I usually only wear it to the gym, because for some reason, it’s difficult to open up a conversation at the nightclubs by talking about the throughput of routers.


This morning, I didn’t travel anywhere to watch the launch of the Cisco CRS 3. Instead, I decided to save some time and watch the video webcast from my office — not because I was only dressed in a T-shirt, but because I didn't have a lot of time to travel back and forth. In an unrelated matter, Cisco is banking on more companies using video for corporate purposes to help sell CRS 3 routers to carriers.


During the webcast Tuesday, Cisco president John Chambers said when CRS 1 was launched, some people questioned whether 92 Terabits per second was a little much.


At the time, it probably was. Although Cisco emphasized the 92 Tbps maximum capacity of CRS 1, when it was launched the cheapest version was actually a 16-slot chassis with 1.2 Terabits per second.


With the CRS 3, the version with 322 Tbps is a multi-shelf system with 1,152 slots.  The four-slot single shelf system actually has 1.12 Tbps.


Cisco’s Patel said with a 322 Tbps CRS 3, you could download the entire contents of the Library of Congress in a second, and all the movies ever made in four minutes. So what would I do with 322 Tbps? I guess I’d never leave the house, except to pickup my official CRS 3 launch T shirt.
