(Non)-Reconfigurable Virtual Topology Design Under Multi-Hour Traffic in Optical Networks

This paper investigates offline virtual topology design in transparent optical networks under a multi-hour traffic demand. The main problem variant addressed here designs a reconfigurable virtual topology which evolves over time to more efficiently utilize network resources (the MH-VTD-R problem). The case of designing a static non-reconfigurable virtual topology which can accommodate the time-varying traffic (the MH-VTDNR problem) is also considered. The objectives are to minimize the number of transceivers, which make up for the main network cost; and, the frequency of reconfiguration (for MH-VTD-R), which incurs additional overhead and potential service disruption.
