A Network Architecture for Reliable Process Group Communication
Seiji Murata, Atsushi Shionozaki and Mario Tokoro
Many applications in distributed systems consist of a set of
processes over multiple network nodes. Traditionally, the communication
to a set of
processes or a process group has been implemented by sending unicast
messages to each member of the group, causing unnecessary network
traffic. In this
paper, we present the design and implementation of the Process Group
Management Protocol (PGMP) which provides
efficient and reliable process group communication using IP multicast.
We also present problems faced with the design of IP
multicast through our experience with PGMP, and propose a
that provides efficient and reliable process group communication
best suited for distributed applications.
