While simulation can provide a good approximation of network behaviour, modeling such a complex network as the Internet is very difficult if not impossible. This paper studies the network's performance from an experimental point of view using the European Academic Network (EAN) as a testbed. In the framework of the EuQoS project, many performance tests have been performed to prove the reliability of data transmissions. The tests show some rough edges which need further analysis, among them the most important being random losses in UDP flows and a great amount of out of order packets. This paper focuses on the study of such out of order packets, searching for their causes, and more importantly to show the effects on real-time traffic such as VoIP, videoconferencing, video streaming, etc

Notably, it has been speculated that the growth rate of router FIBs is surpassing that of its supporting technology and that the deployment of IPv6 is only to make matters worse. In this paper, we propose LISP-MPS, an architecture based on LISP, that isolates the intra-domain routing of an Autonomous System (AS) from its inter-domain routing. The resulting separation implies the decrease of backbone routing table sizes and enables an AS to control the forwarding of traffic inside its network. For a seamless, cost effective, and incremental deployment, LISP-MPS leverages iBGP to implement the LISP mapping system functionality with minimal modification to a small subset of deployed equipment. Finally, an analysis of realistic topologies shows that, despite changing how packets transit a network, the architecture does not lose resilience to failures. Moreover, we show that it can be a viable alternative to BGP/MPLS deployments due to its low implementation cost.

The rapid growth of broadband access has popularized multimedia services, which nowadays contribute to a large part of Internet traffic. Among this content, the broadcasting of live events requires streaming from a single source to a large set of users. For such ...
