Multiple Service UPC/NPC Architecture

Tang Junhua, Tan Kaijun, Gu Shangjie, Zhu Hongwen Department of Electronic Engineering, Shanghai Jiaotong University, China  
Usage/network parameter control (UPC/NPC) is an important measure to guarantee ATM network performance. It can protect network resources and QoS of well behaved users by rejecting malicious as well as unintentional misbehaved user traffic. Since ATM network can provide various categories of service, and the traffic and QoS requirements of each category vary a lot, it is not sufficient to have a UPC/NPC that can only deal with one category of service. In this paper, a new UPC/NPC architecture for multiple service categories in ATM network is proposed, which supports all the existing service categories including CBR, VBR and ABR service. With uniform interface to all the services,it is simple to be implemented. Compatbility of the different ABR flow control schemes is also taken into consideration.The simulation results show that it is a simple yet effective architecture.
