METHOD OF ESTABLISHING CONSTRAINTS ON SERVICE STREAM ROUTING IN A VIRTUAL LOCAL NETWORK

摘要

The present invention relates to a method of establishing constraints on service stream routing in a local or infrastructure network consisting of interconnected bridges, said routing constraints defining those of the internal links between ports of each of said bridges whose establishment is prohibited, one of said bridges being considered to be the network head bridge, said method comprising a step of associating port attributes of bridges of the network, in the course of which a root attribute is associated with the port, which affords the most direct access to said network head bridge, characterized in that it comprises: - a step (200) of obtaining said associations between ports of each bridge and port attributes, and - a step (300) of defining routing constraints relating to each bridge in the course of which the establishment of any internal link between two ports of a bridge is prohibited if one of these two ports is not associated with the root attribute.
