Maxmin lambda allocation for DWDM networks

Proceedings 10th IEEE International Conference on Networks (ICON 2002). Towards Network Superiority (Cat. No.02EX588), 2003
This paper presents a heuristic for solving the discrete maxmin rates for DWDM-based optical subnetworks. Discrete maxmin allocation is proposed as the preferred way of assigning wavelengths to the flows found to be suitable for lightpath switching.

Adaptive QoS schemes in DWDM networks

2002 IEEE International Conference on Communications. Conference Proceedings. ICC 2002 (Cat. No.02CH37333), 2003
In this paper, we present a scheme for dynamic resource management using heterogeneous traffic descriptors. A simple priority class scheme to support basic QoS at the DWDM layer in optical networks is devised. Unlike existing mechanisms that depend on buffer management and scheduling algorithms, our mechanism does not require any electronic buffering ...

Solutions for 80 km DWDM Systems [PDF]

Journal of Lightwave Technology, 2016
Currently discussed solutions for 80 km DWDM transmission targeting inter-data center connections at 100G and 400G line rates are reviewed. PDM-64QAM, PAM4, and discrete multi-tone transmission (DMT) are investigated, while the focus lies on directly ...

Time-domain optical Fourier transformation for OTDM-DWDM and DWDM-OTDM conversion

2011 International Conference on Information Photonics and Optical Communications, 2011
Applications of time-domain optical Fourier transformation (OFT) in ultra-high-speed optical time-division multiplexed systems (OTDM) are reviewed, with emphasis on the recent demonstrations of OFT-based conversion between the OTDM and DWDM formats.

Group switching for DWDM optical networks

Proceedings. 13th International Conference on Computer Communications and Networks (IEEE Cat. No.04EX969), 2005
A new class of interconnection networks called group connectors are introduced. A group connector G (N,n) is a switching network that consists of N inputs and N outputs such that (1) its N outputs are divided into N/n groups with n outputs in each group, and (2) it can provide any simultaneous one-to-one connections from the N inputs to the N outputs ...

Finding protection cycles in DWDM networks

2002 IEEE International Conference on Communications. Conference Proceedings. ICC 2002 (Cat. No.02CH37333), 2003
We introduce the problem of mesh optical network protection based on multiple logical ring/cycles. A two-staged problem formulation as well as classical ring finding algorithms are first discussed. A state-of-art protection cycle (p-cycle) finding algorithm is then proposed.

A fast heuristic for DWDM routing and grooming

2007 6th International Workshop on Design and Reliable Communication Networks, 2007
Due to the capacity granularities inherent to optical networks, routing and traffic grooming are complex problems in DWDM networks. Although algorithms, which are capable of finding (near) optimal solutions exist, they require significant computation time, thus severly limiting the grounds for a more interactive approach to network design or the ...

Arrayed Waveguide Grating DWDM Interleaver

Optical Fiber Communication Conference and International Conference on Quantum Information, 2001
Arrayed waveguide grating DWDM interleavers are proposed and analyzed. With simple design rules, interleavers with low channel cross-talk and flat-top passband can be easily implemented.

An approach to DWDM for real-time applications

IEEE Transactions on Nuclear Science, 2004
Dense wavelength division multiplexing (DWDM) is a technology that assigns to the users of an optical network specific wavelengths or "colors" and mixes them in a single strand of fiber. Heterogeneous data is transmitted simultaneously across lanes of light, which are demuxed at the receiving end and delivered to the clients.
