Abstract
A stack group bidding protocol (SGBP) establishes systems as members of a stack group connected together through one or more networks. When an event, such as establishment of a point-to-point link, occurs on one of the systems, a bid request is sent to each stack group member. Each stack group member then bids for the event. The bid is based on dynamic bid weighting criteria that varies depending on the computation capacity of the member at the time the bid request is initiated. A multichassis multilink PPP (MLP) protocol utilizes the SGBP to conduct multilink PPP sessions for links that either originate or terminate on different physical systems. A L2F forwarding protocol is used in combination with multichassis MLP to forward the links from one system to another system and offers location transparency.
