Abstract
In a packet communications network, the addition or deletion of a connection to the network by a user is governed by a link traffic metric which represents the effective capacity of each link in the network which participates in the packet connection route. A new connection (or deletion) is represented by a compatible metric which allows updates in the link metric by simple vector addition or subtraction. Separate link metrics for a plurality of classes of service permit a much higher efficiency in the exploitation of the link bandwidth than is possible with a single link metric. A packet network using multiple link metrics and efficient metric updating techniques provides increased packet throughput while, at the same time, preserving all class of service guarantees.
