scope:

This document describes the Server Cache Synchronization Protocol (SCSP) and is written in terms of SCSP's use within Non Broadcast Multiple Access (NBMA) networks; although, a somewhat straight forward usage is applicable to BMA networks. SCSP attempts to solve the generalized cache synchronization/cache-replication problem for distributed protocol entities. However, in this document, SCSP is couched in terms of the client/server paradigm in which distributed server entities, which are bound to a Server Group (SG) through some means, wish to synchronize the contents (or a portion thereof) of their caches which contain information about the state of clients being served.
