Dynamic transport-level connection management in a distributed system

A cached state approach to connection management is described. The approach, based on the request-response model of communication, uses implicit connection setup, and dynamic caching of communication state records beyond the time needed by the transport layer. The caching of connection records can reduce callbacks on isolated requests if secure or authenticated communication is required. The cached state approach can provide low latency for request-response interaction by eliminating unnecessary round-trip times from the cost of communication, and does so with little added cost. The effectiveness of the approach depends on locality in communication. Measurements in the V distributed system show the cached-state approach fits well with the observed communication behavior
