Admission control in multi-service IP networks: A tutorial

Abstract

Admission Control (AC) has long been considered as a key mechanism to support Quality of Service objectives in networks. There is a significant base of literature in the area of admission control algorithms, but not all of these algorithms are directly comparable in terms of inputs, outputs or objectives. Current theory does not well describe the when, where, and how to best apply AC in designing network and service infrastructure for multi-service IP networks. This tutorial takes an ontological perspective within which to categorize admission control schemes. Industrystandard architectures (both core and access networks) are used to illustrate some of the key concepts. Two tables are provided to summarize the different approaches for categorization of admission control schemes.

The probability relationship between video’s instantaneous and average aggregate rates

“…MBAC has been studied for more than a decade. We refer interested readers of admission control procedures and classifications to [22,23,38]. Several MBAC algorithms are presented in [7].…”

Pricing and Measurement-based Optimal Resource Allocation in Next Generation Network Services

“…Admission control and QoS have received a lot of attention in the literature; see for example [2], [3] and the references therein. Pricing and providers' revenue maximization are discussed in [8] where they show that a static timeof-day pricing policy would be the optimal policy in the case of a high capacity network.…”

A review of the architecture of admission control schemes in the Internet

“…There have been many proposals of AC schemes for the Internet [5,6]. The starting point was a classical hop-by-hop scheme with per-flow signaling and state in nodes, an approach that raised scalability concerns.…”
