Two-layered IP-over-wavelength-division-multi plexing networks supporting IP and wavelength services are becoming increasingly popular. IP services are traditional data services such as virtual private networks, web browsing, etc., whereas wavelength services are new bandwidth-intensive services with strict quality-of-service (QoS) requirements, such as telemedicine, remote visualization, etc. A generic...
Although establishing stable routes for routing can improve the performance of mobile an hoc networks (MANETs), the improvement will be weakened to a degree for the stability of route is sensitive to the motion of node. In this paper, based on a basic stability-oriented routing scheme, named FORP, we involved two mobility-adaptive mechanisms in it. One mechanism is the real-time update of stability...
This paper proposes a mechanism which allows extending IMS service delivery on the Internet using overlay networks. Dubbed Advanced Quality of Service (AQoS), this solution aims at dynamically providing alternate high-bandwidth routes on the Internet using overlay network measurements to improve connection QoS. The estimation of the achievable QoS in the overlay network makes it possible to adapt...
Clusters of computers have become a cost-effective alternative for parallel and distributed computing systems processing computationally intensive tasks. Normally, clusters are composed of high performance computational nodes linked together by low-latency, high-bandwidth interconnection networks. With the advent of modern optical networking technologies, latency in long-distance links is close to...
