A Photonic Fast Packet Switch for High-Speed Intra-node Routing: Architecture and Delay Analysis
نویسندگان
چکیده
A photonic fast packet switch is proposed for low-latency intra-node routing in high-speed optical networks. Applications are demonstrated in telecommunication and parallel computer environments. The switch fabric is based on integrated directional-coupler technology. It has low complexity and is geometrically suitable for realestate e cient single substrate implementation. The switching architecture relies on time-division multiplexing an optically-coupled tree-structured active routing stage. Both synchronous and asynchronous TDM operation modes are modeled and analyzed to obtain packet bu ering and total switching latencies.

Architecture and Analysis of Fast Packet Switches Based on Time-Multiplexed Photonic Fabrics
This paper proposes and evaluates two related fast packet switching architectures based on time-division multiplexed integrated photonic fabrics. The architectures are targeted towards low-latency inter-node switching and intra-node routing in high-speed networks. The inter-node switch achieves output packet queueing via asynchronous time-division multiplexing a strictly-nonblocking photonic fa...
متن کاملHigh-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...

This paper demonstrates the design of an Arrayed Waveguide Gratings (AWG) based optical switch. In the design both physical and network layer analysis is performed. The physical layer power and noise analysis is done to obtain Bit Error Rate (BER). This has been found that at the higher bit rates, BER is not affected with number of buffer modules. Network layer analysis is done to obtain perfor...

Abstract- Efficient message delivery in city environment is required to ensure driver’s safety and passenger’s comfortability. In cities of developed nations, routing of data in vehicular Ad hoc Network (VANET) faces many challenges such as radio obstacles, mobility constraints and uneven nodes distribution. These factors primarily makes communication between vehicles complex. To overcome and t...
متن کاملMulti-Stage Fiber Delay Line Buffer in Photonic Packet Switch for Asynchronously Arriving Variable-Length Packets
We study photonic packet switches to support asynchronously arriving variable-length packets. A scheduler for contention resolution is operated in electrical domain even when data street of the buffer is provided in optical domain. In this scheme, the scheduler may be a bottleneck. To compensate the gap of high-speed optical transmission and slow-speed electronic processing, we propose a multi-...
