Optical TDM Sorting Networks for

by High-Speed Switching Rajgopal, Rajgopal Kannan, Daeshik Lee, Kyungsook Y. Lee, Harry F. Jordan
"... The general time-space-time switching problem in telecommunications requires the use of multichannel time slot interchangers. In this paper, we propose two multichannel time slot sorters which sort N time division multiplexed (TDM) optical inputs, arranged as N frames with N time slots per frame ..."

Compiled Communication for All--optical TDM Networks

by Xin Yuan, Rami Melhem, Rajiv Gupta - In Supercomputing’96 , 1996
"... While all--optical networks offer large bandwidth for transferring data, the control mechanisms to dynamically establish all--optical paths incur large overhead. In this paper, we consider adapting all--optical multiplexed networks in multiprocessor or multicomputer environment by using compiled com ..."

A Bandwidth Allocation Scheme in Optical TDM Network

by Abdelilah Maach, Hassan Zeineddine, Gregor V Bochmann
"... Wavelength Routing (WR) and Optical Burst Switching (OBS) are two optical network techniques that have received enormous attention over the last decade. However, the two techniques are plagued with many problems. The main concern with WR is the inefficient bandwidth utilization. On the other hand, t ..."
Abstract - Add to MetaCart
, the problem with OBS is resource contention and burst dropping. In this paper, we propose a new scheme to share network resources using Time Division Multiplexing (TDM) instead of the statistical multiplexing employed in optical burst switching. To avoid contention and improve bandwidth utilization, we resort

Pipelined Transmission Scheduling in All-Optical TDM/WDM Rings

by Xijun Zhang And, Xijun Zhang, Chunming Qiao - In Proc. Int'l Conference on Computer Communication and Networks , 1997
"... Two properties of optical transmissions, namely, unidirectional propagation and predictable propagation delay, make it possible to pipeline packet transmissions in alloptical networks. In this paper, we study the problem of scheduling All-to-All Personalized Communication(AAPC) in unidirectional TDM ..."

A Distributed Algorithm for Least Constraining Slot Allocation in MPLS Optical TDM Networks

by Hassan Zeineddine, Gregor V. Bochmann
"... Abstract- In this paper, we propose a distributed approach for the least constraining slot allocation scheme in all-optical TDM networks (LC) that was introduced in a previous work. The driving force behind our proposal is the employment of the LC scheme in a GMPLS context. After describing the basi ..."
