Abstract

We have developed an on-line shared path protection algorithm featuring adaptive alternate routing for primary and backup paths, wavelength reservation based first-fit wavelength allocation, and coordinate backup path reconfiguration. Results show that the proposed scheme performs better than the shortest disjoint path routing and better than the fixed disjoint alternate path routing in terms of blocking probability.
