Abstract
RPC latencies and other network-related delays can frustrate mobile
users of a distributed file system. Disconnected operation helps, but
fails to use networking opportunities to their full advantage. In
this paper we describe partially connected operation, an extension of
disconnected operation that resolves cache misses and preserves client
cache consistency, but does not incur the write latencies of a fully
connected client. Benchmarks of partially connected mode over a slow
network indicate overall system performance comparable to fully
connected operation over Ethernet.
