Problem Definition

This problem is concerned with the most efficient use of redundancy in load balancing on faulty parallel links. More specifically, this problem considers a setting where some messages need to be transmitted from a source to a destination through some faulty parallel links. Each link fails independently with a given probability, and in case of failure, none of the messages assigned to it reaches the destination. (This assumption is realistic if the messages are split into many small packets transmitted in a round-robin fashion. Then the successful delivery of a message requires that all its packets should reach the destination.) An assignment of the messages to the links may use redundancy, i.e., assign multiple copies of some messages to different links. The reliability of a redundant assignment is the probability that every message has a copy on some active link, thus managing to reach the...
