MULTI-CLASS CONNECTION ADMISSION CONTROL METHOD FOR ASYNCHRONOUS TRANSFER MODE (ATM) SWITCHES

摘要

A multi-class connection admission control (CAC) method that supports cell loss and delay requirements. In this model-based CAC, the source traffic is described in terms of the usage parameter control (UPC) parameters. Through analysis and approximations, simple closed-form methods to calculate the bandwidth required to meet guarantees on quality of service (QoS) are used. In addition to being robust, the CAC achieves a high level of resource utilization and can be easily implemented for real-time admission control.
