Research On Routing Technology In Openflow Environment
Zhang Ca · 2014
The OpenFlow technology originated from Stanford University brings a revolution to the internet innovations.OpenFlow splits the functionality of control and forwarding,and employs centralized hierarchy as well as flow-based forwarding mechanisms,compared to traditional networks.These innovations make network administrators to be able to change functionalities even after the physical devices have already been deployed(also known as Software Defined Network).Since OpenFlow has so many advantages over traditional network,it is known as the main competitor of future internet.Routing is recognized as an essential functionality of a network,however traditional fully-distributed routing mechanism doesn't properly fit in an OpenFlow network because of the change in network architecture.Thus after some investigation and research,we design and implement a routing framework that fits in the current environment in which OpenFlow network co-exists with traditional network.
