Cisco addresses legit P2P in Supervisor enhancement – CBRonline.com

Cisco Systems has unveiled both a product enhancement and a series of architectural templates to enable enterprise networks to address the challenge of legitimate peer-to-peer apps such as the Groove feature in Microsoft Office.

The product side of the announcement involves a deep packet inspection capability, delivered via a hardware upgrade to the Supervisor engine on its flagship 6500 switches, essentially introducing additional Cisco-designed ASICs to handle “DPI at multi-gigabit rates,” said Neil Walker, the company’s head of product marketing for core and foundation technologies in Europe.

There arises a need to be able to differentiate between good P2P and bad, which is where the Programmable Intelligent Services Accelerator (PISA) upgrade to Supe32 comes in. “It’s akin to what we’re doing on the carrier side with the P-Cube technology for broadband policy management,” said Walker.

“There the carrier can determine who you are, what you’re doing and the bandwidth you’re consuming to do it. In this case, we’re enabling enterprises to enable wanted P2P and block the unwanted,” he went on. “For instance, two employees might be allowed to exchange IM messages, but not if one of them has just accessed some sensitive data on an internal database.” PISA is not, however, in any way based on the P-Cube technology, but rather the result of internal development, he went on.
