Data Center TCP (DCTCP) is an Explicit Congestion Notification (ECN)-based congestion control and Active Queue Management (AQM) scheme. It has provoked widespread interest because it keeps queuing delay and delay variance very low. There is no theoretical reason why Data Center TCP (DCTCP) cannot scale to the size of the Internet, resulting in greater absolute reductions in delay than achieved in...
Managing bandwidth sharing at bottlenecks is a challenge as old as packet switched networks. When equal senders compete for bandwidth of a bottleneck, it is desirable not only to enforce an instantaneous sharing of the scarce resource but also to prevent permanently active customers from suppressing less active customers. Moreover, it is desirable to incentivize shifting load to non-congested networks...
Today, Network Virtualization (NV) plays an important role in the networking research and gains increasing interest in the business environment. In addition to technical enhancements, NV also allows more differentiated business models diversifying the traditional Internet Service Provider (ISP) role. A crucial prerequisite for such a new business world is a description methodology that allows the...
This paper presents the final architecture for Cognitive Future Internet Element Management and in-network Dynamic Protocol Composition, as well as the results and insights gained by an prototype implementation and experiments performed. The high complexity of today's network infrastructures and the demand for reliable and robust but inexpensive networks stimulated research on evolving networks to...
