Paper Abstract

The Internet consists of a network of networks. Internet users and service provides want to provide and receive multiple services. The legacy networks till now have provided narrow bandwidth that has restricted the range of services. Asynchronous Transfer Mode (ATM) can simultaneously deliver multiple services over one network and today ATM has become a component of the Internet. An ATM switch can deliver current Internet data using UBR or ABR services. Unspecified Bit Rate (UBR) using AAL5 is the most common offering these days for data transport. Because UBR does not guarantee any QoS categories and it is a `best effort' service, cell-discarding protocols must coexist. Congestion control is always a host topic for data networks. In data networks many flow mechanisms to resolve network congestion have been proposed. Cell loss is one of the most important and critical categories for traffic management of data networking. We compare the well-known Early Packet Discard for UBR with Quantum Flow Control for ABR services with TCP over ATM. Simulation results are provided that allow a comparison of both techniques.
