题目:Dynamic Lightpath Scheduling in Optical WDM Grid Networks
摘要：
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.
