Abstract:
A method for admitting a new connection having a given service priority level in a packet communications network that includes a plurality of constrained resources including switching nodes and transmission links, each having a capacity, said method comprising the steps of:generating, for each constrained resource that may be selected to effect said new connection, and for each service priority level, a total effective bandwidth represented by a sum of individual effective bandwidths of previously admitted connections;determining a plurality of effective bandwidths for said new connection, said plurality of effective bandwidths respectively being associated with said given service priority level and lower service priority levels, and being based on a loss criterion;admitting said new connection if constrained resources can be selected from among those of said constrained resources for which said step of generating developed said total effective bandwidth, such that for each of the selected resources, for said given priority level of said new connection and for all lower priority levels, the sum of said total effective bandwidth and said determined effective bandwidth is less than said capacity.
