Cisco CRS-3 to disrupt Hollywood?

John Chambers

Amazing the alarm bells that hype can sound. Cisco's claims that the new CRS-3 core router's 322Tbps capacity can download every movie ever made in four minutes has Hollywood quaking, according to TIME, which said "it could be the business equivalent of an earthquake for the likes of Universal Studios and Paramount Pictures."

  • Cisco defends its Borderless Submitted by Cisco Subnet on Thu, 03/18/2010

    Cisco latest Borderless Networks announcement, which included some new low-priced stackable switches, is viewed by some analysts as more of a defensive than offensive move by the company. The price points and modular uplink upgrade capabilities are seen by Oppenheimer & Co. as a response to HP and Juniper, rather than a capability the two competitors would have to respond to.

    Sorry to say good-bye by Brad Reese

    The editors here at Network World are sorry to say good-bye to Brad Reese and his popular On Cisco blog. Brad has been a staple here at Cisco Subnet for three years. During that time, he has covered every aspect of the Cisco landscape, never failing to intrigue readers with his often controversial style. But all good things run their course and Brad has decided that it was time to dedicate more time to his business ventures. Although no one can fill Brad's shoes, Cisco Subnet has another... 58

    Friday Foray: Where I identify myself and what I stand for professionally. by Michael Thompson

Isn't it patently obvious that I'm a networking genius, capable of fixing problems with either hardware, software or firmware by looking at it cross-eyed? Am I not a paragon of even-handedness, without bias for or against any particular side in an argument, regardless of my personal opinions?   Umm, no. OK, so who am I really? You can see my official bio over to the right of this post, but it doesn't go into near enough detail...

I'll conclude the discussion this week, and ask for your help to build a list of "but you can't do ______ with a 2-switch lab". In short, though, I think you can practice most STP-related config for CCNP SWITCH, with the exception of 802.1s MSTP. The STP topology may be a bit boring, but you can practice the commands. To get a sense for... 2

    Reliably auditing your cloud provider security from the bare silicon on up. by Jamey Heary

    RSA, Intel and VMware have teamed up to bring us their proof of concept for reliably auditing and securing infrastructure cloud services. Their new solution is called the Hardware Root of Trust. One of the biggest issues with cloud services is that there's no reliable mechanism that allows cloud customers to audit their providers security when and how they want to. Cloud customers want the ability to run their own security audits, ensure that proper security measures are always in place...
