Connectivity at the edge of an enterprise network is more than just a wired or wireless

LAN infrastructure. Enterprises must chose infrastructure vendors that can integrate

wired and wireless networking products

Is SDN for me?

•

Programmable network - sounds like engineering. Perhaps very useful for

data centers as they have lot of switches.

•

Does SDN have relevance to University/Campus? I have heard that SDN is a

solution looking for problem to solve.

Well, SDN is definitely great for Data Centers, and, when you enable SDN in

Wi-Fi infrastructure, it is even greater for the Enterprise

Summary



The datacenter was where the need for SDN first surfaced and was most

keenly felt, but SDN is applicable across the enterprise network.



SDN is the only way to achieve unified wired-wireless network

experience that does not lock you with a vendor



OpenFlow is the open standards way to do SDN (otherwise it becomes
