Outline and discuss with your course mate the design of a scheme that uses message retransmissions with IP multicast to overcome the problem of dropped messages. Your scheme should take the following points into account:
i)there may be multiple senders; ii)generally only a small proportion of messages are dropped; iii)unlike the request-reply protocol, recipients may not necessarily send a message within any particular time limit.
Assume that messages that are not dropped arrive in sender ordering.
