3-5 Operation Spanning T ree Algorithm is a hierarchy (or tr ee) of priorities that bridges establish between themselves. This hierarchy guarantees that primary and r edundant data paths are clearly deÞned at all times, so that the network is continuously available to users. In a multiple bridge environment, one bridge in the network establishes i[...]
