“…Wavelength division multiplexing (WDM) is one method for achieving these concurrent multiple channels. A large amount of research has been accomplished on WDMbased systems [4], [13]. The majority of this has been to develop multiple-access multiple-channel protocols on star architectures using tunable transmitters and receivers [7].…”

Abstract-We consider the problem of realizing several common communication structures in the all-optical Partitioned Optical Passive Stars (POPS) topology. We show that, often, the obvious or "natural" method of implementing a communication pattern in the POPS does not efficiently utilize its communication capabilities. We present techniques which distribute the communication load uniformly in the POPS for four of the most common communication patterns (all-to-all personalized, global reduction operations, ring, and torus). We prove that these techniques provide optimal performance in the sense that they minimize the time required to deliver the messages from each node to its neighbors.

“…This eliminates the need for a complicated scheduling protocol design. The LAMBDANET network [19], with a similar network architecture, has been proposed for voice traffic transport and video distribution applications. An experimental demonstration was performed to establish the feasibility of a 16-port star-coupler network using commercially available components.…”

Abstract-In this work scaling of an optical broadcastand-select network based on a passive star coupler is explored for avionics applications. Each client in the network is equipped with a transmitter unit and a multichannel receiver capable of receiving signals from all other clients connected to the star coupler. We propose a connecting node concept to scale the number of clients supported by the architecture. These connecting nodes act as bridges between star couplers, enabling the organization of several star couplers into a topology with additional clients. This design is modeled in the PhoenixSim simulation environment, and system-level simulation results are reported. We then propose the ring topology and dimension-N topology to interconnect and scale star couplers. Finally we compare the ring and dimension-N topologies in terms of scalability limit at different crossing traffic loads, revealing the trade-offs between latency, system complexity, and scalability. Our study shows that a robust, lowlatency network of up to hundreds of clients, sufficient for current and next-generation avionics applications, can be built using off-the-shelf and near-term commercial technology.

“…Several optical networks have been proposed [3], and a few have been or are being implemented. Optical WDM network testbeds include LAMBDANET [9], Rainbow [7], the All Optical Network (AON) [1] , and Lightning [8]. Two main alternatives have emerged in the design of WDM networks: single-hop and multihop networks.…”

The Supercomputer Supernel (SSN} is a highperformance, scalable optical interconnection nelwork I or supercompulers and worksaiion cMsers based on asynchronous, wormhole-rouing switches. The WDM oplical backbone extends the geographic coverage range from inerdepartmenal io campus and even o mefropol2an areas w2h dynamically reconfigurable direct or muUi-hop connections. The neiwork provides very high-speed integrated services, supporling connedion oriented, guaranteed bandwidth fraffic as well as daagram Iraffic. The firsi networking level of The iwo-level SSN archiiecure is electronic and consists of crossbar meshes locally interconnecting workstations, supercomputers, peripheral devices and mass memory. At a higher networking level, an optical backbone network supporting multzple wavelength division multiplexed (WDM) channels allows communication between devices connected to distinct crossbar meshes. In this paper, we focus on the protocols of the WDM optical backbone network and address the issue of integration of the electronic wormhole-routing LAN with the optical backbone.
