Scaling of ABR parameters using a parallel control scheme in ATM networks

This paper proposes a new parallel control scheme with feedback control (PCFC) for ABR services in ATM networks. The information from a source is split into a number of streams for delivery over separate parallel connections. At the receiver, the original information is reconstructed using the cells received from the parallel connections. Traffic splitting of PCFC achieves two advantages for the network performance: reduction of traffic burstiness and load balancing. By combinations of analysis and simulation, this paper studies how the ABR parameters should be scaled when PCFC is used and the advantages of PCFC compared with other existing schemes.
