A statistical bandwidth allocation and usage monitoring algorithm for ATM networks

A load control method and load monitor function are proposed for continuous bit-rate-oriented (CBO) and variable bit-rate (VBR) services in asynchronous transfer mode networks. The allocation algorithm features low complexity and optimizes quality of service and statistical multiplexing gain for variable bit-rate sources. The need to implement a monitor function to verify the assumptions made by the load control is demonstrated. Every single connection is monitored and the negative cumulative distribution of the cell rate compared with an envelope. The load monitor function ensures the proper functioning of the load control mechanisms under all input conditions
