Abstract
The present invention provides a method for establishing an inter-domain path that satisfies wavelength continuity constraint. The fPCE stores a virtual topology comprised by border nodes of all domains. The present invention uses parallel inter-domain path establishment method to decrease the influence from WCC. Compared with the sequential process way in prior art, it enhanced the resource utilization and decreased computation delay.
