Enhanced transport protocols

The book presents mechanisms, protocols, and system architectures to achieve end-to-end Quality-of-Service (QoS) over heterogeneous wired/wireless networks in the Internet. Particular focus is on measurement techniques, traffic engineering mechanisms and protocols, signalling protocols as well as transport protocol extensions to support fairness and QoS. It shows how those mechanisms and protocols can be combined into a comprehensive end-to-end QoS architecture to support QoS in the Internet over heterogeneous wired/wireless access networks. Finally, techniques for evaluation of QoS mechanisms such as simulation and emulation are presented. The book is aimed at graduate and post-graduate students in Computer Science or Electrical Engineering with focus in data communications and networking as well as for professionals working in this area

EuQoS: End-to-End QoS over Heterogeneous Networks

The IST European Project EuQoS ("End-to-End QoS over Heterogeneous Networks") has defined a NGN architecture that builds, uses and manages the end-to-end QoS path across different administrative domains and heterogeneous networks (UMTS, xDSL, Ethernet, WiFi and Satellite access networks and IP/MPLS domains). The architecture follows a model more similar to Internet open architecture than to IMS: it provides to the end user a clear interface that allows it to request (without changing its Application Signaling protocol) which kind of service is required, regardless of the Service Provider particular policies (meeting regulators? and Internet users? Net Neutrality requirement). This allows the Network Operator to take advantage of the new Internet Services as the driver for a new commercial offer based on advanced connectivity to the end user. In this article we present the defined QoS Framework, which has been developed and validated by the Project

EuQoS: End-to-End Quality of Service over Heterogeneous Networks

The EuQoS (End-to-End QoS over Heterogeneous Networks) IST Integrated European Project aimed to define a Next Generation Network architecture that builds, uses and manages end-to-end QoS across different administrative domains and heterogeneous networks (UMTS, xDSL, Ethernet, WiFi, Satellite and IP/MPLS). The EuQoS architecture preserves the openness and the decentralized decision model of the actual Internet, runs on off-the-shelf hardware and network equipment, and allows end users to request various services without changing the Application Signaling protocol, while meeting regulators’ and users’ Net Neutrality requirements. This paper presents the key elements of the EuQoS architecture and describes the main results obtained in field trials performed on a fully-functional EuQoS system prototype developed over a pan-European testbed. Furthermore, the paper discusses the main strengths of the system and the issues related to its actually deployment on a large scale, from both technical and market points of view
