Claim Text:
1. A method for compressing data over a link, the method comprising: receiving a first compressed data stream and a second compressed data stream at a network node, the second compressed data stream being generated through higher-layer compression of a data stream at an upstream node; identifying a first occurrence of a data block in the first compressed data stream; performing link-layer compression on at least the second compressed data stream to obtain a compressed traffic flow, wherein performing link-layer compression on at least the second compressed data stream comprises identifying a second occurrence of the data block in the second compressed data stream, and replacing the second occurrence of the data block in the second compressed data stream with a link-layer compression symbol associated with the data block, the first compressed data stream being a different data stream than the second compressed data stream; and forwarding the compressed traffic flow from the network node to a next hop node on the link.
