Survey of SDN based Packet Classification Techniques

Nilofar Landage | Dr. Tanuja Dhope ^[3]

Abstract: Generally nodes in the communication network are configured as both data section and control section are kept together. All arrived packets are checked inside control section and then it decides route for that packet based on the current flow in the network. Then data section forwards the packet according to route. The main problem with this approach is if network operator wants to expand the network he has to reconfigure all the nodes as control section and data section are kept together that maintain global view of the network. Software Defined Networking (SDN) technology is very helpful in achieving the functionalities like quality oriented service delivery, security, scalability, automatic fault localization and verification of network. The key of Software Defined Network is fault tolerance, in which SDN quickly recover from the occurred fault & can work on highly scalable network also describes multiple link failure, but all these functionalities are solely dependent on packet classification. Packet classification is the first step in network processing for identifying different applications and protocols that exist on the network system. SDN promises to improve programmability, reduced latency and high performance. To achieve these promises there is a need to improve packet classification mechanism.
