Routing and wavelength assignment of scheduled lightpath demands
In this paper, we present algorithms that compute the routing and wavelength assignment (RWA) for scheduled lightpath demands in a wavelength-switching mesh network without wavelength conversion functionality. Scheduled lightpath demands are connection demands for which the setup and teardown times are known in advance. We formulate separately the routing problem and the wavelength assignment p...
متن کاملBlocking analysis of dynamic lightpath establishment in wavelength-routed networks
Abstract-In this paper, we analyze the blocking probability of dynamic lightpath establishment in wavelength-routed networks. By using the destination-initiated reservation (DIR) method as a case study, we analyze traffic blocking occurring due to insufficient network capacity as well as traffic blocking caused by outdated information. Simulation results show the proposed models to be highly ac...
متن کاملDynamic Lightpath Establishment in Wavelength-Routed WDM Networks
In wavelength-routed WDM networks, a control mechanism is required to set up and take down all-optical connections. Upon the arrival of a connection request, this mechanism must be able to select a route, assign a wavelength to the connection, and configure the appropriate optical switches in the network. The mechanism must also be able to provide updates to reflect which wavelengths are curren...
متن کاملLightpath Establishment in Wavelength-Routed WDM Optical Networks
Wavelength-division multiplexing (WDM) technology has been improving steadily in recent years, with existing systems capable of providing huge amounts of bandwidth on a single fiber link. WDM systems are currently being deployed in long-distance telecommunication networks on a point-to-point basis, with the optical signals being converted back to electronics at each node. The electronic switchi...
متن کاملA Weighted Iterative Conflict Reducing Algorithm for Sliding Scheduled Lightpath Provisioning in WDM Optical Networks
In WDM optical networks, the consistent variation of quality of service (QoS) demand has conducted the advent of sliding scheduled traffic, which does not have a rigid deadline and allows flexible sliding within a large time window. In this paper, the static sliding scheduled lightpath demand (SSLD) provisioning problem is formulated into a weighted partition coloring model. Then, a heuristic a...
