The concept of safety vector can guide efficient fault-tolerant routing on interconnection networks. The safety vector on the hypercube is based on the distance of a pair of nodes...
Let S be a set of n points in IRd and let t > 1 be a real number. A t-spanner for S is a directed graph having the points of S as its vertices, such that for any pair p and q o...
New architectures have recently been proposed and deployed to support end-to-end advance reservation of network resources. These architectures rely on the use a centralized schedul...
A family of well known problems on graphs includingthe shortest path problem and the data flow analysis problem can be uniformly formulated as a fixed-point problem on graphs. We ...
We address the problem of routing packets on multiple, router-disjoint, paths in the Internet using large-scale overlay networks. Multipath routing can improve Internet QoS, by rou...
