It's Open Season for OpenFlow

It's Open Season for OpenFlow | Routing and Switching | Scoop.it
Cisco Systems Inc. (Nasdaq: CSCO) appears to be resisting OpenFlow. At a customer/partner event in London last week, CTO Padmasree Warrior made remarks that could indicate a proprietary SDN strategy is unfolding -- at least, that's how SearchNetworking interpreted it. One quote from Cisco VP Ram Velaga is that OpenFlow isn't production-ready.

OpenFlow Doesn't Always Mean Commodity

OpenFlow Doesn't Always Mean Commodity | Routing and Switching | Scoop.it
OpenFlow's power is that it lets an external controller tell switches and routers what to do. Those instructions are stored in ternary CAMs (TCAMs), a type of memory that switches and routers just happen to have.
When you apply OpenFlow to an ordinary switch, the TCAMs do the job, but not very impressively, Proch says. The recently announced G8264 from IBM includes 48 10Gbit/s ports -- hardly a commodity box -- but it supports less than 100,000 OpenFlow flows. "We've done research that says a 10Gbit/s Ethernet port might have 2.5 million flows," Proch says.
