Abstract

A communication system such as a distributed packet switch, is described, including multiple nodes with bi-directional transmission links between the nodes, each link comprising of a set of.
multiple links in parallel. The system provides an automatic balancing the aggregate capacity of one set of links in a proportion "M:N" to the aggregate capacity of the other set of links under varying link conditions, including one or more individual link failures in one or both sets of links.
