Mesh hybrid communication network

摘要

A communication network comprises a plurality of physical media. The physical media may be sensitive to disturbances that are different from one physical medium to another, such that a failure in one physical medium may not effect communication in other physical medium of the communication network. The nodes of the communication network comprise a plurality of physical layers units and MAC units pairs, each pair connected to a different physical medium. The transfer of massages among the network nodes on the plurality of different physical media is done in a transparent way by upper layers of communication unit of the network nodes.
