First Claim
Patent Images
1. A method for a high-speed multimedia content switch with compressed Internet Protocol (IP) header comprising:
- at a header compression unit;
retrieving an IP packet having a header and a payload from an IP network;
compressing the header of the IP packet;
appending the payload to the compressed header to create a compressed IP packet;
establishing a multi-protocol label switch (MPLS) virtual circuit through a plurality of IP routers terminating at a header decompression unit of the IP packet, wherein the header decompression unit is the IP packet'"'"'s final destination;
converting the compressed IP packet into a MPLS packet;
transmitting the MPLS packet through the MPLS virtual circuit;
at the header decompression unit;
re-converting the MPLS packet into the compressed IP packet at the destination; and
decompressing the header of the IP packet.

Abstract
An IP packet (210) is retrieved having a header and a payload. The header of the IP packet is compressed. The payload is appended to the compressed header to create a compressed IP packet. A multi-protocol label switch (MPLS) virtual circuit is established through a plurality of IP routers terminating at a destination of the IP packet. The compressed IP packet is converted into a MPLS packet (230). The MPLS packet (230) is transmitted through the MPLS virtual circuit. The MPLS packet is re-converted into the compressed IP packet at the destination. The compressed IP packet is decompressed at the destination (170).
