A method and system for controlling network traffic with different tags within the same connection by applying policies for each tag are disclosed. A method is disclosed in which incoming traffic is received. A traffic class is assigned to the traffic class. Outgoing traffic is controlled based on the assigned policy for the incoming traffic.

Method and system for controlling network traffic within the same connection with different packet tags by varying the policies applied to a connection

Methods, apparatuses and systems facilitating enhanced classification of network traffic that extends beyond analysis of explicitly presented packet attributes and holistically analyzes data flows, and in some implementations, related data flows against known application behavior patterns to classify the data flows. Implementations of the present invention facilitate the classification of encrypted or compressed network traffic, or where the higher layer information in the data flows are formatted according to a non-public or proprietary protocol.

Heuristic behavior pattern matching of data flows in enhanced network traffic classification

Methods, apparatuses and systems directed to an automatic network traffic discovery and classification mechanism that includes dynamically adjusted traffic discovery thresholds. In one implementation, the dynamic discovery thresholds are adjusted based on analysis of one or more operational parameters associated with network traffic discovery, and/or network traffic characteristics. The present invention in one implementation can be configured to dynamically adjust one or more thresholds or range limits that affect the behavior of the automatic traffic classification mechanism, such as the rate at which new traffic classes are added to a traffic classification database. One implementation of the present invention minimizes the user intervention often required with the use of static traffic discovery thresholds.
