|Title:||Hierarchical interdomain routing and light-path provisioning in optical networks|

|Abstract:||Given the increasing adoption of DWDM networking technology, there is now a growing need to address distributed interdomain light-path provisioning issues. Although interdomain provisioning has been well studied for packet/cell-switching networks, the wavelength dimension presents many additional challenges. To address this challenge, a detailed hierarchical routing GMPLS-based framework for provisioning all-optical and optoelectronic multidomain DWDM networks is presented. The scheme adapts topology abstraction schemes to improve routing scalability and lower interdomain blocking probabilities. Related interdomain light-path RWA and signaling schemes are also tabled. Performance analysis results are also presented to demonstrate the effectiveness of the proposed mechanisms along with directions for future research work. (C) 2006 Optical Society of America.|
