Abstract

A communications technique which permits incoming multi-link point-to-point (PPP) packets of a common PPP frame to be simultaneously transmitted across more than one outgoing link in a multi-link bundle. Specifically, during LCP negotiations, a multi-link PPP originator assigns itself a unique endpoint discriminator value and informs all its immediate PPP peers by sending the latter, via a first bundle of outgoing links, an LCP Endpoint Discriminator packet containing this value. Each of these immediate PPP peers assumes, as its endpoint discriminator, the value that has been provided to it in the LCP Endpoint Discriminator packet it receives from the originator and then sends an LCP Endpoint Discriminator packet containing this same endpoint discriminator value, via a second bundle of outgoing links, to all of its immediate PPP peers. This is recursively repeated until all hierarchically inter-connected multi-link PPP devices at one end of a pipe, which fan-out from the originator, have set their endpoint discriminators to the same value. Consequently, all the links in the pipe will be viewed, by the multi-link protocol, as part of a common bundle.
