Improving the resilience in IP networks

Quality of service issues of IP networks are mostly related to guaranteeing bandwidth for flows. However, many interactive real-time applications also require this bandwidth in an uninterrupted fashion. The paper describes how multipath routing and local failure reaction can be employed to provide uninterrupted QoS to applications. We show how multipath route sets can be found in reasonably meshed networks and how multipath routing can be used to save on the spare capacity required in case of link failures.

Towards carrier-grade next generation networks

This paper describes the objectives, concepts and solution approach of the KING research project, which is carried out jointly by a number of leading research organisations in Germany. Our overall objective is to develop efficient solutions for carrier-grade IP networks. The distinguishing characteristic of our approach is that we pursue an integrated solution to achieve the carrier-grade requirements for quality of service (QoS) and resilience as well as low-cost efficient operation.
