Abstract
Methods and apparatus for dynamically adapting the degree of compression used in compressing data based upon the type of contents contained within a packet are disclosed. According to one aspect of the present invention, an apparatus that forwards data across a digital communications network includes a compression switch, a compression system, and an output interface. The compression switch receives the data, determines a content type associated with the data by examining the data, and assigns a compression level to the data in response to the determined content type. The compression system is arranged to compress the data based upon the compression level, while the output interface forwards the compressed data across the network. In one embodiment, the apparatus also includes a network congestion estimator that determines a level of network congestion.
