Abstract
A system providing a multiple number of virtual channels in a computer system having a smaller number of physical channels. Multiple queues are provided that are mapped to channels. The mapping of the queues to the channels changes depending on the message traffic and priority of the queues. Queues of lower priority are preempted if a higher priority queue needs a channel.
