Design, Implementation, and End-to-end Evaluation of a Measurement-based Admission Control Algorithm for Controlled-Load Service

چکیده
The Internet Engineering Task Force (IETF) is considering the adoption of controlled-load service as a standard for relaxed real-time service on the Internet. The ability of relaxed real-time services to achieve high level of utilization and still provide acceptable quality of service depends crucially on the use of measurement-based admission control (MBAC) algorithms. MBAC algorithms admit new connections based on measured usage of existing ones. In this paper we describe the design and implementation of an MBAC algorithm for controlledload service on a router running FreeBSD 2.2.2 kernel. We then present an end-to-end evaluation which shows that controlled-load service, supported by an MBAC, reduces the packet loss rate and delay variation of real-time traffic while maintaining network efficiency.

Admission Control Based on End-to-End Measurements
This paper proposes a controlled-load service that provides a network state with bounded and well known worst-case behavior. The service is primarily developed for real-time applications. The full system for achieving quality of service to the application consists of an admission control combined with forward-error correction. The admission control is used to limit the packet-loss probability t...

This paper reports the design and the implementation results of a Controlled Load service in a bridged/switched Local Area Network (LAN). In contrast to other approaches, the service was built based on traac aggre-gation and simple two level Static Priority scheduling within LAN switches. All complex control functions such as the per-ow packet classiication, policing and traac reshaping are onl...

The Differentiated Service (DS) framework has been developed by the Internet Engineering Taskforce (IETF) to provide Quality of Service (QoS) on the Internet. Load Control Pre-Congestion Notification (LC-PCN) is a measurement based DiffServ implementation that uses Admission Control and Flow Termination to control the load in a domain. In this paper a preliminary performance evaluation of Admis...
متن کاملDesign and Simulation of Adaptive Measurement-based Admission Control Algorithms for Controlled-load Service
The purpose of call admission control in Controlled-load Service network is to offer a Quality of Service (QoS) commitment to guarantee that QoS bounds are not violated. The traditional way of achieving this goal by declaring the worse case traffic descriptors for the incoming calls results in poor bandwidth utilization. In recent years, measurement-based admission control has become an appeali...
