MULTI-LEVEL PACKET CLASSIFICATION AND ROUTING IN A DISTRIBUTED COMPUTE ENVIRONMENT

摘要

A multi-level classification scheme for classifying subscriber traffic at a network node coupled between subscribers of network services and provider s of the network services includes two levels of classification. The subscri ber traffic is received at the network service node. A first portion of the subscriber traffic is selectively routed from a plurality of first level rou ters to a plurality of second level routers within the network service node. The first portion of the subscriber traffic is then selectively routed from the second level routers to network applications executing within the netwo rk service node for processing.
