Open networking &

SDN

5

Legacy network….

• High CAPEX

• Expensive !!!!

• Hardware, Software, Solution !!!!

• Lots of time

• Livers.......

6

Legacy network….

• High OPEX

• Lots of hardware -> Lots of protocols

• Hard to trace error

• Livers…….

7

Open Networking & SDN

• Open, Standard network control method

• Reduce cost (white box switch)

• Reduce CAPEX & OPEX

• High flexibility

• Easy to control network(s).

8

How SDN works?

• Decouple Control and Data planes.

• Switch become stupid.

• Centralize network intelligent.

• Network infrastructure is abstracted from the applications.

How about SDN switch ?• OpenvSwitch + Linux + PC

• Hardware Switch + Network Operating System

• Protocol-Independent Forwarding

• Programmable Protocol-Independent Packet Processor.

• Protocol Oblivious Forwarding
