This paper proposes two lightpath-level active rerouting algorithms, namely, the least resources rerouting algorithm and the load balanced rerouting algorithm, in all-optical WDM networks with alternate routing and traffic grooming. The proposed algorithms consist of three major components to be determined: i) when the rerouting algorithm initiates, ii) which lightpath is rerouted, and iii) which...
This paper proposes a new dynamic-alternate routing algorithm for all-optical WDM networks without wavelength conversion in order to reduce the connection blocking probability. The main idea in the proposed dynamic-alternate routing algorithm is to try to route the traffics according to a predefined optimal probability distribution. The problem for finding the optimal probability distribution has...
