基于Open Flow的软件定义网络(SDN)中的转发设备不便于支持新协议的转发,因此协议无感知转发(Protocol Oblivious Forwarding,POF)技术被提出.本文基于POF技术和Open Flow控制器POX,设计并实现了一种支持POF技术的SDN控制器,POF控制器可以充分利用POF转发设备并且体现了SDN的可编程性.同时,我们基于POF控制器搭建了POF试验床,实验结果表明POF控制器能够有效地管理POF网络,并提供高效的控制功能.
The Open Flow-based software-defined Networking could not easily support forwarding of the new protocols,thus Protocol-Oblivious Forwarding technology is proposed. On the basis of POF technology and Open Flow controller POX, this paper designs and implements the controller which supports POF technology, employs the full potentials of POF devices and reflects the programmability of SDN. Meanwhile, we construct a network testbed based on POF controller, and experimentally illustrate that POF controller can effectively manage the POF network and provide the controlling functionality with high performances.
