The unifying network architecture has contributed to a wave of work on layered network evolution. The undertaking of this paper is twofold: This paper's first-of-its-kind examination of the problems of logical link mapping and traffic flow routing unveils that backhaul traffic, a flow loop that occurs at any lower link layer below the traffic layer except its own, could happen in the traffic flow...
In this paper, we consider hybrid circuit/packet networks. A hybrid circuit/packet network consists of a circuit network co-existing with a packet network; generally the packet network is embedded on top of the circuit network. However, in certain cases such as the DOE energy sciences network (ESnet), the circuit network and the packet network are deployed side-by-side (e.g. they have common end-node...
A multimetric QoS routing protocol (MQOLSR) is proposed in this paper, which providing different QoS for different applications flow in an ad hoc network. The protocol, which integrates QoS measurement and packet forwarding, expands the topology discovery and routing computing mechanism of the OLSR protocol. It can provide different routing and forwarding service according to different application...
The issues of network performance and reliability in wireless access networks have become indispensable due to the increasing needs for communication services anywhere and anytime. Traditional design of wireless backhaul networks has a simple tree-like structure which is vulnerable to network failures. To protect services against network component/facility breakdown, reliable network design is required...
