Transparent load sharing for parallel networks
Abstract
A method for improving communications in a bridge network between end nodes involving sensing trunking configurations and executing binding schemes to make certain daughter bridges involved in the trunking conditions behave as a plurality of bridges and forward messages in the correct time sequence. This can be done by creating "forwarding groups" associating different groups as networks connected to those daughter bridges.
