A Workgroup Model for Smart Pushing and Pulling

  • Caching has long been used to reduce average access latency, from registers and memory pages cached by hardware, to the application level such as a web browser retaining retrieved documents. We focus here on the high-level caching of potentially shared networked documents and define two terms in relation to this type of caching: Zero latency refers to the condition where access to a document produces a cache hit on the local machine, that is, there is little or no latency due to the network (we assume that latency due to local disk and memory access is insignificant in comparison to network latency). A document with zero latency usually has been placed in the cache after a previous access, or has been pulled there through some prefetching mechanism. Negative latency refers to automatic presentation, or push, of a document to a user based on a prediction that the user will want that document. With an ideal system, a user would be presented with documents either that she was about to request, or that she would not know to request but that would be immediately useful to her.
