End-to-End Quality of Service Over Heterogeneous Networks : Springer : 9783642097997 : 3642097995 : 19 Oct 2010 : The Internet has evolved from an academic network for data applications such as le transfer and net news, to a global general-purpose network used for a variety of different applications?electronic mail, voice over IP, television, peer-to-peer le sharing, video streaming and many more. The heterogeneity of applications results in rather different application requirements in terms of bandwidth, delay, loss, etc. Ideally, the underlying network supports Quality-of-Service parameters such that - plications can request the desired services from the network and do not need to take actions by themselves to achieve the desired communication quality. Initially, the Internet was not designed to support Quality of Service, and only in the last decade have appropriate mechanisms been developed. Those mechanisms operate mainly on theInternetProtocol(IP) level,butalso network-speci cmec
