METHOD AND APPARATUS FOR CLASSIFYING IP DATA

A method and methodology are provided for classifying Internet Protocol (IP) data in a packet switch network. Data may be received at a first node and classified based on source routing information of said data. The source routing information may be provided within LSRR/SSRR of IPv4 data or may be provided within a routing header of Ipv6 data.
