The Bit Repository protocol supports standard archive operations initiated by clients - Put, Get, Replace, Delete - as well as operations for working on lists of files - GetFileIDs, GetChecksums, GetAuditTrails. It also supports a special operation for monitoring Bit Repository components. Finally it supports the exchange of Alarm messages, which can be initated by any Bit Repository component.
