End-To-End QoS Frameworks for Heterogeneous Networks - A Survey

One of the main concerns of the current Internet, in terms of Quality of Service, is guarantying end-to-end delivery of services over heterogeneous networks, where more than one management entity exists. Due to the complex, underdeveloped business relations among ISPs and a low level of trust, new QoS frameworks are being designed to guarantee reachability, availability and network performance. This survey is an effort to briefly discuss some of the developments in the QoS for heterogeneous networks research area. The survey is part of the ongoing QAF research project, which aims to develop an end-to-end QoS aware framework for networks and middleware.
