Openflow-enaling innvation in Campus Networks Problems occurred Background
Networks has become part of the critical infrastructure
Of our businesses, homes and schools.
- Because of the huge installation base of equipment and protocols and the reluctance to use production flow to carry out experiments, network innovation has encountered a huge bottleneck, people think that the network has been rigid.

Demand
- The external interface of the commercial switch is too narrow, the internal flexibility is hidden, it can be said that the commercial switch is too cumbersome.
- and the open switch port is almost impossible, which involves the benefit of the supplier
- There is a way to solve the problem, one is the PC side, there is poor performance, insufficient resources. One is a programmable hardware FPGA, but the resources are low
Problem solving openflow need to meet:
- High performance, low consumption
- Ability to provide extensive research
- Separation of experimental flow and production flow
- Meet the requirements of the current supplier closed platform
The openflow switch needs to meet:
- Working with the flow table with action
- Forwarding a stream table to a given port
- Encapsulating the forwarding flow table to the controller
- Drops a stream of packets
- Supports general processing of switches
- Has a secure channel to connect the controller and the switch
- The OpenFlow protocol provides an open and standard way for the controller to communicate with the switch.
