ABSTRACT:
A multi-channel network is disclosed in which channels can be designated as “active” or “inactive” and changes can be made from one channel to another based on a metric which is a function of various channel parameters such as throughput and stability. In one form, the metric is a linear combination of factors such as the mean of the round trip time sequence of previous packets (indicating throughput) and the sample variance of the sequence of retransmission timeout values computed for previous transmission attempts (indicating stability). Regardless of the specific form of the metric or the estimation procedures for the channel parameters, these factors are combined using user-specified weights which permit the user to emphasize the relative importance of individual factors, thereby characterizing the strategy whereby “active” or “inactive” paths are used.
