简介:
Lightpath scheduling is an important capability in emerging wavelength-division multiplexing (WDM) optical grid networks to reserve resources in advance for a specified time period while provisioning end-to-end lightpaths. In a dynamic environment, the end user requests for dynamic scheduled lightpath demands (D-SLDs) need to be serviced without the knowledge of future requests. Even though the starting time of the request may be hours or days from the current time, the end-user however expects a quick response as to whether the request could be satisfied. We propose a two-phase approach to dynamically schedule and provision D-SLDs. Experimental results show that our proposed two-phase dynamic lightpath scheduling approach can greatly reduce network blocking.
