A Bandwidth Determination Method for IPv6-based Networks

摘要

Accurate measurement of bottleneck and available bandwidths in network paths is a problem that has intrigued researchers for years. Numerous tools and techniques have been developed to determine bottleneck and available bandwidths but none of these methods provide a simple solution that is accurate, efficient, and flexible. Such a solution is simply not practical for IPv4 networks. Fortunately, the next generation Internet Protocol, IP version 6, has the functionality necessary to implement feedback mechanisms to assist in accurate bandwidth estimations. In this paper we present a method to accurately and efficiently determine the network bandwidth in IPv6 networks through the use of a proposed timestamp option for the IPv6 hop-by-hop extension header.
