Recent explosion of high-bandwidth applications and scientific collaboration has expedited the need for scheduled transmission of data to multiple scientific sites around the world. Advance reservations (AR) promote efficient bandwidth utilization, particularly when demands are high. The collaborative nature of modern science calls for more flexible(More)
In this paper we investigate the multicast advance reservation problem in wavelength division multiplexed (WDM) optical networks. Under the advance reservation traffic model (also know as scheduled traffic), connection requests specify their start time to be some time in the future and also specify their holding times. Traditionally, in WDM networks, the(More)
Current scientific data applications require advanced network provisioning systems to support the transport of large volumes of data. Due to the availability of diverse computing and Grid clusters, these applications can benefit from anycasting capabilities. In contrast to unicasting, anycast routing allows the selection of a node from a group of candidate(More)
