Next-generation application identification

Next-generation application identification recognizes Web-based and other applications and protocols at different network layers using characteristics other than port number. With next-generation application identification, applications are identified by using a downloadable protocol bundle containing application signatures and parsing information. Here, identification is based on protocol behavior and session management. Next-generation application identification builds on the legacy application identification functionality and provides more effective detection capabilities for evasive applications such as Skype, BitTorrent, and Tor. It improves the accuracy of existing applications, enables dynamic update of the detector engine without requiring Junos OS code upgrade, and increases the application count to around 2900.
