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.
