USE OF BOOKING FACTORS TO REDEFINE AVAILABLE BANDWIDTH

摘要

A method of assigning effective bandwidth to a physical or logical link for propagating multiple virtual paths through a switched digital communications network is described. Switching nodes within the network have more than one interconnecting link in order to provide redundancy in the event of link failure. The effective bandwidth is assigned to each link according to dual multipliers or booking factors. The first booking factor is used for provisioning the link on set up and the second booking factor is for re-routing in the event of link failure.
