    This paper addresses the multicast wavelength assignment (MC-WA) problem in wavelength-routed WDM networks with full light splitting and wavelength conversion capabilities. Current approaches are based on the multicast switch model that supports only split-convert (S-C) switch scheme. This scheme leads to redundant wavelength conversions for a given multicast request. In this paper, we propose a n... View full abstract»

  • Overspill routing in optical networks: a true hybrid optical network design

    To efficiently support the highly dynamic traffic patterns of the current Internet in large-scale switches, we propose a new hybrid optical network design: Overspill Routing In Optical Networks (ORION). By taking advantage of the reduced (electronic) processing requirements of all-optical wavelength switching, the electronic bottleneck is relieved. At the same time, ORION achieves a level of stati... View full abstract»

    Given a combination of unprotected and dedicated edge-disjoint path (1+1) protected connection requests and a finite set of fiber types, we consider the problem of allocating fibers on the links of a WDM network at minimum cost, such that all connection requests can be simultaneously realized. Each fiber type, is characterized by its capacity and its cost per unit length, where costs reflect an ec... View full abstract»

  • Design and provisioning of WDM networks with multicast traffic grooming

    In this paper we consider the optimal design and provisioning of WDM networks for the grooming of multicast subwavelength traffic. We develop a unified framework for the optimal provisioning of different practical scenarios of multicast traffic grooming. We also introduce heuristic solutions. Optimal solutions are designed by exploiting the specifies of the problems to formulate Mixed Integer Line... View full abstract»

  • OSNR optimization in optical networks: modeling and distributed algorithms via a central cost approach

    This paper addresses the problem of optical signal-to-noise ratio (OSNR) optimization in optical networks. An analytical OSNR network model is developed for a general multilink configuration, that includes the contribution of amplified spontaneous emission and crosstalk accumulation. The network OSNR optimization problem is formulated such that all channels maintain a desired individual OSNR level... View full abstract»

  • Traffic grooming in path, star, and tree networks: complexity, bounds, and algorithms

    We consider the problem of traffic grooming in WDM path, star, and tree networks. Traffic grooming is a variant of the well-known logical topology design, and is concerned with the development of techniques for combining low speed traffic components onto high speed channels in order to minimize network cost. Our contribution is two-fold. In the first part of the paper we present a wealth of result... View full abstract»

  • A frame division method for prioritized DBA in EPON

    Dynamic bandwidth assignment (DBA) in Ethernet Passive Optical Networks (EPONs) is based on a frame structure that is broadcast downstream periodically. In most DBA schemes supporting priorities, frames are divided to allocate bandwidth for different traffic classes according to weights, which, however, are often either determined empirically or supposed to be pre-known. How to determine these wei... View full abstract»

  • Separating resource reservations from service requests to improve the performance of optical burst-switching networks

    Publication Year: 2006

    In this paper, we introduce a new signalling architecture called Dual-header Optical Burst Switching (DOBS) for next generation burst-switching optical networks. DOBS decouples the resource reservation process from the service request process in core nodes and allows for delayed scheduling to be implemented. This relaxes the constraints on burst scheduling operations and allows the offset sizes of... View full abstract»

  • Using switched delay lines for exact emulation of FIFO multiplexers with variable length bursts

    In the literature, research has been published extensively on how one achieves exact emulation of First In First Out (FIFO) multiplexers for fixed-size cells (or packets) using optical crossbar Switches and fiber Delay Lines (SDL). In this paper, we go a step further and propose a new architecture that achieves exact emulation of FIFO multiplexers for variable length bursts. Our architecture consi... View full abstract»

  • Shared fiber delay line buffers in asynchronous optical packet switches

    Packet contention is a major issue in asynchronous optical packet switching networks. Optical buffering, which is implemented by fiber delay lines (FDLs), is fundamental to many optical switch implementations for resolving contention. Most existing optical buffering implementations are output-based and require a huge amount of FDLs as well as larger switch sizes, which impose extra cost on the ove... View full abstract»
