Abstract
Method and system for adapting access to a packet switching network including a dynamic bandwidth adjustment mechanism which continuously monitors the mean bit rate of the signal source and the loss probability of the connection. These values are filtered to remove noise and then used to test whether the values fall within a pre-defined acceptable adaptation region in the mean bit rate, loss probability plane. Values falling outside of this region trigger bandwidth adaptation procedures which, in turn, result in acquiring a new connection bandwidth, and determining new parameters for the adaptation mechanism. Furthermore, the mechanism controls the number of connections that can be adapted by a single processor, given its processing capability. It ensures fairness between the connections in the sense that it prevents a single connection from using, on the average, a greater portion of the processor capacity than it should.
