An Efficient K-Shortest Paths Based Routing Algorithm
We present an efficient K-shortest paths routing algorithm for computer networks. This Algorithm is based on enhancements to currently used link-state routing algorithms such as OSPF and IS-IS, which are only focusing on finding the shortest path route by adopting Dijkstra algorithm.

Performance optimization of intelligent optical networks by multiple alternate routes based on the K-shortest path algorithm [PDF]
Blocking probability is one of the key factors to evaluate the routing and wavelength algorithms for intelligent optical network. Two kinds of Dynamic K-Shortest Path (DKSP) Algorithms were designed. One is based on Linear Link Weight Function (LW) and the other is based on Piecewise Linear Link Weight Function (PLW).

K-Shortest Paths Q-Routing: A New QoS Routing Algorithm in Telecommunication Networks
Actually, various kinds of sources (such as voice, video, or data) with diverse traffic characteristics and Quality of Service Requirements (QoS), which are multiplexed at very high rates, leads to significant traffic problems such as packet losses, transmission delays, delay variations, etc, caused mainly by congestion in the networks.

Heuristic Methods for Delay Constrained Least Cost Routing Using<tex>$k$</tex>-Shortest-Paths
The delay constrained least cost (DCLC) problem is to find the least cost path in a graph subject to a delay constraint. First formulated in the context of routing in computer networks, the DCLC model also applies to problems of path planning and other decision problems. DCLC is NP-complete. Many heuristic methods have been proposed for it.

Route Finder: Efficiently Finding k Shortest Paths Using Constraint Programming
In this paper, we describe a Constraint Programming (CP) route finding application for a container transportation company. Mathematically, this amounts to finding the k shortest paths in a directed graph. However the nature of the business constraints rule out known algorithms such as Dijkstra's.

A k shortest path algorithm for adaptive routing in communications networks
The problem of finding k shortest loopless paths with distinct initial links from one node to each other node arises in several important contexts for adaptive routing in communication networks. One context is the construction or adaptive reconstruction of routing tables where a sequential routing algorithm is used, and another context is ``delta ...

Random Regular Graph and Generalized De Bruijn Graph with k-Shortest Path Routing
Random regular graph (RRG) has recently beenproposed as an interconnect topology for future large scaledata centers and HPC clusters. While various studies havebeen performed, this topology is still not well understood. RRGis a special case of directed regular graph (DRG) where eachlink is unidirectional and all nodes have the same number ofincoming ...
