Assignee: ARRIS ENTERPRISES LLC
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 8:
9. A method for providing enhanced steam classification for IPinIP tunneled traffic, comprising:
implementing at least one classifier, wherein the at least one classifier provides 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;
receiving a tunneled IPinIP packet that includes an IPv6 header, an IPv4 header; and a TCP/UDP header;
using 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; and
based on the comparison, mapping the IPinIP packet to a service flow identified by the classification parameters.
