1. A method for sharing reserved bandwidth between a plurality of connections issuing from a port of a node, comprising:

  • determining a connection bandwidth for each connection of said plurality of connections;

    determining an aggregate bandwidth for all connections of said plurality of connections issuing from said port, said aggregate bandwidth less than a sum of said connection bandwidth for all connections; and

    further computing an equivalent capacity for each said connection “

    i”

    in determining said aggregate bandwidth, where said equivalent capacity is a function of,a. Ri the access bit rate of said connection,b. mi the average bit rate of said connection,c. bi the average burstiness of said connection,andcomparing said aggregate bandwidth with a maximum access rate for said port, and in the event that said aggregate bandwidth does not exceed said maximum access rate, reserving said aggregate bandwidth for said port.
