That was the overriding theme after the first day of the inaugural Open Networking Summit, a conference dedicated to software-defined networking (SDN)and OpenFlow, the open source API defined to enable multivendor switches and routers to be programmable.
The VAR Guy’s head is spinning. Just about every major networking company — Brocade (Nasdaq: BRCD), Cisco Systems (NASDAQ: CSCO), Juniper Networks (NYSE: JNPR), Hewlett-Packard (NYSE: HPQ) and more — claims to lead the software-defined networking (SDN) market.
