Abstract: A method, system and computer program product for transmitting content across a link in a communications network. In an embodiment, the method comprises examining traffic in the network at a sender end of the link to determine if the traffic is carrying compressed content; when the traffic is carrying compressed content, decompressing at least one portion of the compressed content; and checking a cache to determine if the cache has content matching the at least one decompressed portion of the content. In an embodiment, the method further comprises when the cache has content matching the at least one decompressed portion of the content, determining an identifier associated with the at least one decompressed portion of the content; and using the identifier to reconstruct, at a receiving end of the link, the at least one decompressed portion of the content.

Abstract: A method and an apparatus allowing a system interfaced with a network to continue functioning in a diminished capacity, even when the system is temporarily disconnected from the network. Unmodified applications running on the system which initiate a network-related operation during system isolation are coerced into a fast-fail behavior by fast-fail mechanisms residing in the system's network layer kernel modules.
