ADMISSION CONTROL IN A SELF AWARE NETWORK

摘要

A method of admission control in a Self Aware Network carrying at least one existing user (z) specifying at least one Quality of Service metric (qw ). The method includes receiving (202) a user request for admission of a connection from a source node to a destination node in the network specifying at least one Quality of Service metric (qv ). The source node then finds(203) paths (P(s,d)); creates(206) link Quality of Service matrices (Qw (i,j)); sends(208) probe traffic over the network; and uses the traffic to obtain (210) a Quality of Service matrix (q^'w (i,j)). The source node computes (212) estimated link Quality of Service matrices (Q^ w (i,j)) and computes(214) path Quality of Service matrices (K^w ) for the Quality of Service metrics, based on the estimated link Quality of Service matrices(Q^w (i,j)). The user request is rejected or accepted(216, 218, 220) based on the path Quality of Service matrix.
