The invention from the Spanish university engineering group describes mechanisms that sequentially and completely explore a network of transparent bridges to discover and establish multiple bidirectional paths, disjointed in links only or disjointed in nodes and links, between pairs of bridges bordering the network, as well as a network bridge that implements these mechanisms.
The origin frontier bridge sends multicast road establishment packages to the destination bridge, that propagate until reaching the destination bridge, which confirms to the frontier bridge each disjunct road establishment by means of a message from destination to the origin, that leaves identified and established the bidirectional path in each bridge.
The roads are automatically deleted when a certain time passes without confirmation, without being used or when sending the border bridge an explicit delete packet of a road or all roads. The number of created paths is parameterizable and both ends communicate with each other the number of output links available, in order to know the maximum number of disjoint paths feasible.
These multiple disjoint paths created by border bridges can be used by an entity or protocol for load sharing, reliability enhancement or other purposes.
The present technology has a special application for ethernet switches for enterprise networks and data centers.
The group seeks to reach license agreements, commercial agreements with technical assistance or collaboration agreements with companies in the telecommunication sector, for the application of its technology in Ethernet switches for business networks and data centers.
