Hierarchical Optical Switching: A Node-Level Analysis
نویسندگان
چکیده
We consider hybrid optical devices consisting of a waveband (transparent optical) and a wavelength (opaque OEO) switch. Such hybrid devices are suitable for supporting hierarchical optical paths (wavelength and waveband paths). We study the node-level costperformance tradeoffs using both analytical models and simulations. The results demonstrate a significant cost reduction that could be achieved for a moderately small reduction of throughput.

High-speed All- Optical Time Division Multiplexed Node
In future high-speed self-routing photonic networks based on all-optical time division multiplexing (OTDM) it is highly desirable to carry out packet switching, clock recovery and demultplexing in the optical domain in order to avoid the bottleneck due to the optoelectronics conversion. In this paper we propose a self-routing OTDM node structure composed of an all-optical router and demultiplex...
متن کاملOptical Fast Circuit Switching Networks Employing Dynamic Waveband Tunnel
We propose a novel dynamic hierarchical optical path network architecture that achieves efficient optical fast circuit switching. In order to complete wavelength path setup/teardown efficiently, the proposed network adaptively manages waveband paths and bundles of optical paths, which provide virtual mesh connectivity between node pairs for wavelength paths. Numerical experiments show that oper...

Analyzing motion patterns in traffic videos can be exploited directly to generate high-level descriptions of the video contents. Such descriptions may further be employed in different traffic applications such as traffic phase detection and abnormal event detection. One of the most recent and successful unsupervised methods for complex traffic scene analysis is based on topic models. In this pa...

متن کاملOn Burst Assembly in Optical Burst Switching Networks – A Performance Evaluation of Just-Enough-Time
On the way towards an architecture for a new QoS-supporting and scalable Internet, the IPover-photonics approach seems to be very promising. One possible solution in this domain is optical burst switching (OBS), a concept combining advantages of optical circuit and packet switching. After an introduction to OBS as well as the reservation mechanism Just-EnoughTime (JET) we present an approximati...
