A Scalable Heuristic for Hybrid IGP/MPLS Traffic Engineering - Case Study on an Operational Network

In current IP networks, a classical way to achieve traffic engineering is to optimise the link metrics. This operation cannot be done too often and can affect the route of a lot of traffic. Multiprotocol Label Switching MPLS opens new possibilities to address the limitations of IP systems concerning traffic...

Basic Abstractions for an Autonomic Network Architecture

The ANA Autonomic Network Architecture project aims at providing a framework to flexibly host, interconnect, and federate multiple heterogeneous networks in an autonomic way, i.e. without requiring active human intervention. The guiding design principle is to strive for a maximum degree of flexibility at all levels of the architecture in...

A Machine Learning Approach to Improve Congestion Control Over Wireless Computer Networks

This paper presents the application of machine learning techniques to the improvement of the congestion control of TCP in wired/wireless networks. TCP is suboptimal in hybrid wired/wireless networks because it reacts in the same way to losses due to congestion and losses due to link errors. The paper thus proposes...

Machine-Learnt Versus Analytical Models of TCP Throughput

This paper first studies the accuracy of two well-known analytical models of the average throughput of long-term TCP flows, namely the so-called SQRT and PFTK models, and show that these models are far from being accurate in general. The simulations, based on a large set of long-term TCP sessions, show...

Peer-to-Peer Behaviour Detection by TCP Flows Analysis

The use of Peer-to-Peer (P2P) applications is growing dramatically. It concerns applications like Gnutella, Kazaa or eDonkey. These applications sometimes represent as most as 50% of Internet traffic. So, it became important for ISPs to detect these applications. As the TCP port can change, an identification based on TCP gate...
