In this paper we deal with reconfiguration of virtual topology. Routing of traffic through virtual
and physical topology is investigated. Practical model for minimizing the difference between …

We propose a linear formulation for traffic routing in optical networks after the virtual
topology design (VTD). The formulation maximizes the amount of traffic the network is able …

In this paper, we consider reconfiguration of the virtual topology of a wavelength division
multiplexed (WDM) optical network. The traffic generated by the higher layers is dynamic; …

This paper studies the design of regular virtual topologies to facilitate optical packet
switching in networks with arbitrary physical topologies. The regular virtual topology problem …

Optical networks based on WDM technology are potential candidates for future networks.
The design of virtual topology using routing and wavelength assignment algorithms is the …

In wavelength routed wavelength division multiplexing (WR-WDM) networks, a set of
lightpaths (all-optical communication paths) defines the virtual topology. In the event of a …

This paper studies the virtual topology reconfiguration problem due to traffic changes in
optical WDM networks. The reconfiguration problem has twin goals of minimizing the total …

WDM optical networks represent the direction to the future high capacity wide-area network
applications. By creating the optical paths between several nodes in the core networks …

Abstract Reconfiguration in a Wavelength-Routed Optical Network is a process of
rearranging a virtual topology to meet traffic demands that change over a period of time. This …

This article addresses the problem of finding a static virtual topology design and flow routing
in transparent optical wavelength division multiplexing networks under a time-varying …
