ABSTRACT:
A simple admission control mechanism for IP based networks is provided. The decision on whether a new flow is accepted is based on the link load information on the paths from the source to destination. The new flow is accepted when the link load is less than a threshold. When at least one of the links on all of the available paths is larger than the acceptable threshold, access is denied to the flow. More than one threshold level may be used. Under the multiple threshold scenario, the traffic may be divided into different classes. The admission control mechanism helps to ensure a network that is not heavily congested.
