Fast and accurate estimation of shortest paths in large graphs
Computing shortest paths between two given nodes is a fundamental operation over graphs, but known to be nontrivial over large disk-resident instances of graph data. While a numbe...

Survivable IP network design with OSPF routing
Internet protocol (IP) traffic follows rules established by routing protocols. Shortest path based protocols, such as Open Shortest Path First (OSPF), direct traffic based on arc w...

Tailoring neighborhood search for the internet protocol network design problem with reliability and routing constraints
The Internet Protocol Network Design Problem with Reliability and Routing Constraints (IPRR) can be shortly stated as follows. A telecommunication network is given in terms of a s...

Flying over a polyhedral terrain
We consider the problem of computing shortest paths in three-dimensions in the presence of a single-obstacle polyhedral terrain, and present a new algorithm that for any p 1, comp...

Near-Linear Time Construction of Sparse Neighborhood Covers
This paper introduces a near-linear time sequential algorithm for constructing a sparse neighborhood cover. This implies analogous improvements (from quadratic to near-linear time)...

Restoration by path concatenation: fast recovery of MPLS paths
A new general theory about restoration of network paths is first introduced. The theory pertains to restoration of shortest paths in a network following failure, e.g., we prove th...

Two techniques for fast computation of constrained shortest paths
Abstract-- Computing constrained shortest paths is fundamental to some important network functions such as QoS routing, which is to find the cheapest path that satisfies certain co...

Partially Dynamic Algorithms for Distributed Shortest Paths and their Experimental Evaluation
— In this paper, we study the dynamic version of the distributed all-pairs shortest paths problem. Most of the solutions given in the literature for this problem, either (i) work...
