Alternative Best Effort (ABE) Router (Providing a Low-Delay Service within Best Effort)

Abstract

In all the applications that transfer binary data such as bulk data transfer will seek to minimize the overall transfer time. This paper proposes a novel approach for Internet Protocols (IP) networks. This paper presents Alternative Best Effort (ABE) Router that relies on the notion of providing low delay at the disbursement of fewer throughputs. The main objective of the proposed approach is to retain the simplicity of the original Internet single-class best-effort service while providing low delay to interactive adaptive applications. With ABE, each best effort packet is marked as either blue or green. The presence of green packets in every router ensures low bounded delay. Based on the nature of the traffic and global traffic conditions of a particular application the color the packets is chosen for every router. At the time of congestion the green packets are more likely to be dropped than the blue packet. The proposed router requirements aim at enforcing benefits for all types of traffic; as the green packet achieves low delay and the blue traffic receives at least as much throughput as it would in a flat best effort network. In addition this paper also discuss on ABE service, properties, requirements and usage. Moreover, it discusses the implications of replacing the existing IP best effort service by ABE service.
