Inter-domain lightpath provisioning policy in support of hierarchical multi-target QoSPhotonic Network Communications - Tập 22 - Trang 51-58 - 2011
JianPing Wang, Ke Wang
As the DWDM distributed multi-domain optical networks has been advocated to be the next generation networks, there is a pressing need to propose a set of effective light path provisioning policies. Meanwhile, with the growth of service types, different types of service should be set in different priority levels and pursuit individual QoS requirements. Thus, a new lightpath provisioning policy in s...... hiện toàn bộ
Comparison of p-cycles and p-trees in a unified mathematical frameworkPhotonic Network Communications - Tập 14 - Trang 123-133 - 2007
Aden Grue, Wayne D. Grover
As high-speed networks grow in capacity, network protection becomes increasingly important. Recently, following interest in p-cycle protection, the related concept of p-trees has also been studied. In one line of work, a so-called “hierarchical tree” approach is studied and compared to p-cycles on some points. Some of the qualitative conclusions drawn, however, apply only to p-cycle designs consis...... hiện toàn bộ
Simple Scheduling Algorithms for Use with a Waveguide Grating Multiplexer Based Local Optical NetworkPhotonic Network Communications - Tập 1 - Trang 35-48 - 1999
Michael S. Borella, Jason P. Jue, Biswanath Mukherjee
As the need for greater bandwidth in local-area networks grows, wavelength-division multiplexing (WDM) is gathering attention as a viable successor to Gigabit Ethernet technologies. In this paper we introduce a new WDM optical LAN architecture based on the waveguide grating multiplexer (WGM) rather than the traditional passive star coupler (PSC). An N-port WGM allows N

Spectral, cost and energy efficiencies analysis in WDM MLR networks with OTN switchingPhotonic Network Communications - Tập 34 - Trang 422-431 - 2017
Yabin Ye, Tamara Jiménez, Víctor López
The application of OTN switching can bring significant improvements in the resource utilization to conventional WDM networks. In this paper, spectral, cost and energy efficiencies have been comprehensively analyzed in optical core networks by introducing OTN switching on top of the WDM layer with mixed line rate transmissions for both dedicated protection 1+1 (DP 1+1) and unprotected network scena...... hiện toàn bộ
Aggregation defragmentation algorithm based on channel density and minimum gap in elastic optical networksPhotonic Network Communications - Tập 35 - Trang 1-10 - 2017
Zhe Ding, Zhanqi Xu, Xiaodong Zeng
Spectrum-sliced elastic optical path networks that adopt orthogonal frequency division multiplexing technique can flexibly allocate bandwidth to connection requests and efficiently use the spectrum resources. Setup and tear down of connection requests in the optical channel will generate spectrum fragmentation in dynamic scenarios, which reduces the spectrum utilization ratio and increases the blo...... hiện toàn bộ
Automatic configuration in future semi-transparent distributed optical networksPhotonic Network Communications - - 2007
Marco Ruffini, Donal O’Mahony, Linda Doyle
The recent commercial development of photonic switches has created many new semi-transparent optical architectures with core nodes made up of an all-optical switch controlled by an IP router. The fact that the nodes are transparent to the switched data complicates the implementation of operations such as interface and link configuration. In this article we present first an algorithm that allows th...... hiện toàn bộ
An integrated view on monitoring and compensation for dynamic optical networks: from management to physical layerPhotonic Network Communications - Tập 18 - Trang 191-210 - 2009
A. Teixeira, L. Costa, G. Franzl, S. Azodolmolky, I. Tomkos, K. Vlachos, S. Zsigmond, T. Cinkler, G. Tosi-Beleffi, P. Gravey, T. Loukina, J. A. Lázaro, C. Vazquez, J. Montalvo, E. Le Rouzic
A vertical perspective, ranging from management and routing to physical layer options, concerning dynamic network monitoring and compensation of impairments (M&C), is given. Feasibility, reliability, and performance improvements on reconfigurable transparent networks are expected to arise from the consolidated assessment of network management and control specifications, as a more accurate evaluati...... hiện toàn bộ
Analysis of p-cycle Capacity in WDM NetworksPhotonic Network Communications - Tập 12 - Trang 41-51 - 2006
Dominic A. Schupke
The concept of p-cycles provides many characteristics, which are benficial for deployment and operation in WDM networks. We present a detailed analysis of the resource efficiency addressing several issues, which are essential to WDM networks. This includes novel investigations about the influence of the length of working paths and a detailed redundancy comparison of p-cycles with prevalent protect...... hiện toàn bộ
