ABSTRACTWe discuss the principles of Optical interconnects, and discuss the potential of silicon photonics to provide all the necessary building blocks to construct dense, high-bandwidth, lowpower optical links. We discuss waveguides, wavelength division multiplexing, modulators and photodetectors. We also take a look at the options for implementing light sources, a function which silicon cannot natively provide, with a focus on implementations in the IMEC silicon photonics platform.

The authors present a WDM (Wavelength-Division Multiplexing) based all-optical network architecture, and study scheduled routing on it. Their architecture can be seen as a communication system of parallel multi-core computer or a large-scale high bandwidth routing switch of e.g., telecommunication network. The goal is to construct such a scalable architecture and a supporting routing protocol for it so that no electro-optical conversions are needed on the routing paths, all packets are routed along one of the shortest paths, processor nodes can inject packets constantly into the network, and all the packets injected into the routing machinery reach their targets without collisions. The authors’ CSOT is a sparse network. A large fraction of the nodes are intermediate nodes instead of processor nodes. Only the processor nodes are sources and sinks of packets. The number of all nodes is and is the number of processor nodes in our construction. For scheduled routing to work, the authors consider routing problems as a set of h-relations. They achieved work-optimal routing of -relations for a reasonable size of . The efficiency of routing is based on routing latency hiding which is made possible by WDM and sparseness based increase bandwidth per processor node.

Control Traffic

In this paper, a traffic flow control scheme is presented. Wavelength division multiplexing (WDM) technology have significantly increased the transmission capacity of today’s transport networks, and played an extremely important role in high-speed network. Since high bandwidth wavelength channels will be filled up by many low-speed traffic streams, efficiently provisioning customer connections with such diverse bandwidth needs is a very important problem and is also known as the traffic-grooming problem. Traffic grooming is an extremely important issue for next-generation optical WDM networks.

AbstractOptical Burst Switching (OBS) networks are new emerging techniques that alternate Optical Circuit Switching (OCS) and Optical Packet Switching (OPS) techniques. The high bandwidth of fiber links in these networks, besides WDM (Wavelength Division Multiplexing) helps the Internet to handle the heavy traffic. OBS networks have an important issue that needs to be tackled. These networks are bufferless in their nature, so when two bursts are trying to reserve one wavelength one of them is dropped. This drop can be assumed as an indicator of congestion; as a result, the sending rate will be decreased, despite the fact that the network may not be congested. So, wired protocols like TCP (Transmission Control Protocol) cannot work to their high potential in OBS networks. In this paper, we propose a new scheme based on a probable approach that can distinguish burst drops caused by contentions from burst drops caused by contention, so we can improve the performance of the network. Extensive simulative studies show that the proposed algorithm outperforms TCP Vegas in terms of throughput and packet delivery count.
