A Proposal for an Asymmetric Best-E ort Service
نویسندگان
چکیده
We propose Asymmetric Best-E ort, a novel service to provide a \throughput versus delay jitter" differentiated service for IP packets. With this service, every best e ort packet is marked as either Green or Blue. Green packets, typically sent by real-time applications such as interactive audio, receive more losses during bouts of congestion than Blue ones. In return, they receive less delay jitter. Both Green and Blue services are best-e ort. The incentive to choose one or other is based on the nature of one's tra c and on tra c conditions. If applications are TCP-friendly, those sending Blue packets will receive more throughput but also more delay jitter, than they would if they sent Green packets for a given network state and path.

متن کاملAsymmetric Best E ort Service for Packet Networks
We propose a system and method for providing a \throughput versus delay" di erentiated service for IP packets. We distinguish two types of tra c: type A and type B. It is expected that type A tra c receives less throughput per ow than type B. On the other hand, type A packets experience considerably smaller delay. The method is intended to be implemented in Internet routers. No bandwidth or bu ...
متن کاملABE: Providing a Low-Delay Service within best-effort
We propose Alternative Best-E ort (ABE), a novel service for IP networks, which relies on the idea of providing low-delay at the expense of maybe less throughput. The objective is to retain the simplicity of the original Internet single class, best e ort service, while providing low delay to interactive, adaptive applications. With ABE, every best e ort packet is marked as either green or blue....

Health services and policy research (HSPR) represent a multidisciplinary field which integrates knowledge from health economics, health policy, health technology assessment, epidemiology, political science among other fields, to evaluate decisions in health service delivery. Health service decisions are informed by evidence at the clinical, organizational, and policy level, levels with distinct...
متن کاملA modest proposal for preventing Internet congestion
A simple approach, called PMP (Paris Metro Pricing), is suggested for dealing with congestion in packet networks such as the Internet. It is to partition a network into several logical networks, each of which would treat all packets equally on a best e ort basis, just as the current Internet does. There would be no formal guarantees of quality of service. The separate networks would di er only ...
