A new solution to the K-shortest paths problem and its application in wavelength routed optical networks [PDF]

open access: closedPhotonic Network Communications, 2006
In communication networks, traffic carried over long paths suffers from a higher call blocking probability (CBP) than those carried over short paths. This is a well-known fairness problem. Such a problem becomes more serious in wavelength-routed optical networks (WRONs) due to the wavelength continuity constraint.

Transmission Line Route Selection: An Application of K-Shortest Paths and Goal Programming

open access: closedIEEE Power Engineering Review, 1984
A two-stage solution procedure is developed as a managerial decision making tool in the transmission line route selection process. In stage one, the K least costly alternatives are found, based strictly on monetary considerations. In stage two, the alternative which causes the least amount of social and environmental disruption is selected from the ...

Ak-SHORTEST PATHS ROUTING HEURISTIC FOR STOCHASTIC NETWORK EVACUATION MODELS

open access: closedEngineering Optimization, 1984
Stochastic-network evacuation models require an optimization process to determine the best evacuation routes for a building's occupants. The optimization process developed and applied below is a heuristic based on the K-th Shortest Path Algorithm.

Comparison of k-shortest paths and maximum flow routing for network facility restoration

open access: closedIEEE Journal on Selected Areas in Communications, 1994
In the development of technologies for span failure restoration, a question arises about the restoration rerouting characteristics to be specified. In theory, maximal rerouting capacity is obtained with a maximum flow (Max Flow) criterion. However, rerouting that realizes the k-successively shortest link disjoint paths (KSP) may be faster, easier, and,

An Efficient K-Shortest Paths Based Routing Algorithm

open access: closedAdvanced Materials Research, 2012
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]

open access: closedSPIE Proceedings, 2006
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

open access: closed, 2005
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.
