Lightpath Rerouting in Wavelength-Routed WDM Networks
Rerouting is a viable and cost-effective approach to decrease the blocking probability in legacy circuit-switched networks. We study lightpath rerouting in optical WDM networks in this paper. First, we investigate two different lightpath rerouting strategies, namely, passive rerouting and intentional rerouting. Passive rerouting means the rerouting of existing lightpaths to accommodate new ligh...
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study, we analyze traffic blocking occurring due to insufficient network capacity as well as traffic blocking caused by outdated information.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 کاملEfficient Lightpath Routing in Wavelength-Routed Optical Networks
We propose a new lightpath routing algorithm for WDM optical networks that solves the routing and wavelength assignment (commonly known as RWA) problem dynamically and separately. The RWA problem is partitioned into two subproblems, the routing and wavelength assignment problems, and both of them are solved using the shortest path routing technique. For solving the routing subproblem, an auxili...
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...
