The NSFNET Backbone Network interconnects six supercomputer sites, several regional networks and ARPANET. It supports the DARPA Internet protocol suite and DCN subnet protocols, which provide delay-based routing and very accurate time-synchronization services. This paper describes the design

Abstract: Given the wide range of services to be offered by future optical backbone networks, network survivability becomes a quintessential aspect of network design. The survivability schemes of such networking infrastructures can be realized in two basic forms, viz., restoration

Abstract — This paper addresses the problem of streaming packetized media through a proxy server to a mobile client over multiple wireless channels. We follow a rate-distortion optimized streaming approach. A real-time sender-driven streaming framework is employed at the proxy server to maximize the playback quality at the client. The experimental results show that the proposed algorithm improves the video quality by 1.3-3dB as compared to the conventional system which simply transmits the video data in the order they are displayed. packets ACK/NAK’s

This paper describes new algorithms for throughput optimization in a mobile backbone network. This hierarchical communication framework combines mobile backbone nodes, which have superior mobility and communication capability, with regular nodes, which are constrained in mobility and communication

The problem of reducing power consumption in backbone networks by adopting sleep modes has been extensively studied in the literature. In contrast to previous work, we forecast power consumption and traffic in two operator networks (France Telecom (FT) and Telefónica Investigación y Desarrollo

to switch off network nodes and links while still guaranteeing full connectivity and maximum link utilization. After showing that the problem falls in the class of capacitated multi-commodity flow problems, and therefore it is NP-complete, we propose some heuristic algorithms to solve it. Simulation results

Optical-bypass technology is finally being deployed in carrier backbone networks on a large scale. The reality, however, is that the resulting networks are not truly all-optical; all connections cannot be carried end-to-end solely in the optical domain. While a significant amount of regeneration
