Abstract
A network device includes a memory and a processor. The processor implements at least one classifier to provide classification for tunneled IPinIP traffic based on classification parameters provided by Internet Protocol Version 6 (IPv6) classification encoding, Internet Protocol Version 4 (IPv4) classification encoding, and Transport Control Protocol/User Datagram Protocol (TCP/UDP) classification encodings, wherein one of the IPv6 classification encoding and the IPv4 classification encoding is provided by extension information to provide extended classification capabilities. The processor uses the at least one classifier to compare the classification parameters provided by the IPv6 classification encoding, the IPv4 classification encoding, and the TCP/UDP classification encodings to fields in an IPv6 header, an IPv4 header, and a TCP/UDP header of the IPinIP packet. Based on the comparison, the processor maps the IPinIP packet to a service flow identified by the classification parameters.
