Abstract
An operating system adds an application signature as a tag in a packet header. In one embodiment the tag is inserted as a Q-tag in an Ethernet header. When a network element receives the tagged packet, it uses the tag alone or in combination with one or more additional header fields to map the packet to a network virtualization identifier segregating the application traffic on the network. Services are applied to packets according to network virtualization identifier to enable distributed application of services without requiring network elements to maintain state associated with packet flows.
