Advance reservation for periodic transfers with flexibility

Wavelength Division Multiplexing (WDM) technology enables a lightpath to carry tens of gigabits of data per second. However, many applications may require an optical connection for only short periods of time, and leasing a lightpath full time for that purpose may be too costly. We consider a single...
