"Multimedia Intra-Group Communication Protocol"
In distributed applications, a group of multiple application
processes have to send and receive multimedia
messages by using the high-speed network.
The multimedia message at the application level is decomposed into
multiple smaller packets which are transmitted in the communication system.
In this paper, we discuss the atomic and ordered delivery of messages
at the application level rather than the system level.
In some multimedia applications,
the application processes do not mind if some packets
are lost and in what order packets from different processes are received.
The application process specifies the minimum receipt ratio
'e' (< 1) showing how many percentages
of whole data in each message the destination processes have to be
received at least. The communication system delivers
the packets to the destinations in the group
so as to satisfy the receipt ratio 'e'.
The protocol is based on the
fully distributed control scheme,
i.e. no master controller.
