A Distributed Scheme for Responsive Network Engineering

— Optimal bandwidth utilisation together with resilience and recovery from failure are two key drivers for Traffic Engineering (TE) which have been widely addressed by the IP community. Most current routing protocols deployed in the Internet and the extensions proposed to adapt these protocols for TE are concerned either with optimality or with resilience. This leads to a duplication of routing protocols and algorithms where each of these objectives (optimality, resilience) is addressed by its own protocol or algorithm. The interactions among these protocols introduces additional complexities which do not necessarily translate into equivalent performance gains. This paper aims at the integration of these two objectives into a unified Network Resource Controller. At random time instants the NRC computes bandwidth prices which are used in an automated scheme to dynamically adjust the bandwidths of the network paths in response to the traffic and network equipment conditions. The dis...
