This paper proposes two almost all-optical packet switch architectures, called the “packing switch” and the “scheduling switch” architecture, which when combined with appropriate wait-for-reservation or tell-and-go connection and flow control protocols provide lossless communication for traffic that satisfies certain smoothness properties. Both switch architectures preserve the order of packets...

This paper presents recent progress made in the development of an optical packet and circuit integrated network. From the viewpoint of end users, this is a single network that provides both high-speed, inexpensive services and deterministic-delay, low-data-loss services according to the users’ usage scenario. From the viewpoint of network service providers, this network provides large switching...

We report the first demonstration of all-optical multi-bit address recognition at 250 Gb/s using a self-routing scheme. With bit period being only 4 ps, two address bits from each packet header were used for routing. Photonic packets can be removed(dropped) by a routing switch from network traffic at their destination. The packet-switching bit-error rate was measured to be less than 10(-9) .

Synchronisation is an important and critical issue in high-speed all optical time division multiplexed (OTDM) packet routing and transmission. In this paper we present a technique for separating the clock synchronization pulse from an incoming optical time division multiplexed data packet, based on all-optical switching devices with optical feedback. A 1X2 OTDM router composed of three Symmetri...

Optical packet/burst switching is considered a promising technique to improve the performance of optical networks. Key components in these technologies are the optical switching nodes. Some of these node architectures suffer from internal blocking. Synchronous operation allows overcoming most of the problems introduced by this internal blocking. However, in asynchronous networks internal blocki...

This paper proposes TONAK, an AWGR-based optical switch with distributed control plane. Simulations results for a 128-port switch show high throughput and low average packet latency for offered loads of up to 75%, while achieving an energy efficiency of ≈ 50pJ/bit. Introduction The ever-growing demand for cloud-based services and high-performance computing is posing major challenges to the scal...

Time Sliced Optical Burst Switching is a proposed variant of optical burst switching, in which switching is done in the time domain, rather than the wavelength domain. This eliminates the need for wavelength converters, the largest single cost component of systems that switch in the wavelength domain. We examine some of the key design issues for routers that implement time sliced optical packet...

With the fast development of heterogeneous network services and applications as well as the increasing bandwidth demand, the future transport network is confronted with the requirements for flexible and dynamic service provisioning, high throughput and assurance of quality of service (QoS). To deal with the challenges, photonic packet switching aims to realize a fast switch of the traffic in th...

This is technical report outlining an idea for basic long term research into the architectures for programmable all-optical Internet routers. We are revisiting some of the fundamental tenets of computer science to carry out this work, and so it is necessarily highly speculative. Currently, the processing elements in all-electronic routers are typically fairly conventional von-Neumann architectu...

We describe the design and implementation of a packet-switched ber optic interconnect prototype with a ShuueNet topology, intended for use in shared-memory multiprocessors. Coupled with existing latency-hiding mechanisms, it can reduce latency to remote memory locations. Nodes use deeection routing to resolve contention. Each node contains a processor, memory, pho-tonic switch, and packet routi...
