A Survey on Signature Generation Methods for Network Traffic Classification
Main Article Content
Abstract
Traffic classification provides security to the network systems and provides basics for trusted network management. Network traffic
classification is extensively required mainly for many network management tasks such as traffic policing and flow prioritization. To overcome the
inaccuracy of prior protocol based traffic classification method payload based method is introduced which uses signatures for traffic classification.
Signatures are generated by the session and application information of the packet. Various techniques have been developed to produce accurate and
reliable signatures for traffic classification. This survey paper looks at those techniques of payload based signature generation and compares their
accuracy with other schemes. Issues related to signature generation technique also discussed.
