Abstract
The admission control algorithm implements measurement-based connection admission control using effective envelopes of an arriving traffic aggregate and the service curves of the corresponding departing traffic aggregate. The approach provides the statistical service guarantees to a variety of service classes. According to the admission control algorithm, arriving traffic is admitted if the sum of the effective envelopes of the arriving traffic entering a network and admitted traffic currently in the network is less than or equal to the service curve.
Claims14
A method of performing admission control of traffic flow in an information network, comprising:
- determining a first effective envelope associated with arriving traffic entering said network;
- determining a second effective envelope associated with admitted traffic currently in said network;
- determining a service curve by measuring departing traffic leaving said network;
- and
- admitting said arriving traffic if the sum of the first and second global effective envelopes is less than or equal to said service curve.
A method of performing admission control of traffic flow in an information system, comprising:
- determining a first effective envelope associated with arriving traffic entering said network;
- determining a second effective envelope associated with admitted traffic currently in said network;
- determining a service curve by measuring departing traffic leaving said network;
- and
- admitting said arriving traffic if the sum of the first and second global effective envelopes is less than or equal to said service curve.
