Group communication in network architecture
Seiji Murata ($@B
Many applications in distributed systems consist of a number of
processes running on different hosts.
The execution between these cooperating processes result in the
frequent use of network resources.
So, a mechanism that handles a set of processes as a single group to
which a process can communicate is required.
But, if a process communicates with each member directly, as the
number of processes increase, the more packets have to be sent to the
In this paper, we introduced the following mechanisms to solve this
We designed and implemented the communication protocol called PGMP, that
provides these mechanisms.
PGMP supports group communication system which is
scalable to the number of processes in each group.
Finally we considered the mechanisms needed in a network architecture
to provide multicast base suited at the process level.
- Use of multicast mechanism of the network layer
- Association process group and host group
- Distributed management of group information on each host
