A new proposal for an optical packet-routed network based on a distributed router architecture in a WDM network is described. Buffering, scheduling and wavelength assignment functions are carried out in routers located at the edge of the network. The destination address is encoded by a given wavelength and allows wavelength-routing in optical core routers. This approach avoids processing and ad...

An optoelectronic router with a shuffle exchange network is presented and enhanced by adding micro-optical-electrical mechanical systems (MOEMS) in the network to add the ability to reconfigure the shuffle network. The MOEMS described here are fully connected any-to-any crossbar switches. The added reconfigurability gives the opportunity to adapt for different common application characteristics...

In this paper we describe some recent developments in how optics can be used inside Internet routers to scale capacity and reduce power. At Stanford University we are currently designing a 100Tb/s Internet router with an optical switch fabric that guarantees 100% throughput for all traffic.

Tratflc Matrlx AbstractA detailed analytical traffic model for alloptical wavelength division multiplexing (WDM) photonic packet switched networks is presented and the requirements for buffer size, and link dimensions are analyzed. This paper shows that due to the topology, packets may generate traffic bottlenecks produced by a tendency of the routing scheme to send packets with different desti...

In this paper, we propose a distributed contention resolution scheme to reduce blocking probability in optical burst-switching networks. The scheme takes priority, propagation delay from the ingress router, and the burst-size into account to resolve contention, and guarantees that at least one of the bursts succeeds when contention occurs. We use a control packet to delay transmission of the co...

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...

An electromagnetically induced absorption grating is formed in a three-level atomic vapor under the condition of electromagnetically induced transparency in which the strong coupling beam is replaced by a standing wave. The transmission and reflection behaviors of the weak probe beam are greatly modified at certain frequencies near the two-photon resonance. An all-optical two-port signal router...

S. J. Ben Yoo, Zhong Pan, Haijun Yang, Zuqing Zhu Department of Electrical and Computer Engineering, University of California, Davis, California 95616, USA [email protected] Abstract: This paper proposes and demonstrates an optical-label switching router with all-optical time-to-live, performance monitoring, label swapping, and 2R regeneration. Experimental results of unicast and multicast pa...

This paper first describes the implementation of a protocolindependent self-similar traffic generator in the OPNET modeler. With the support of this traffic generator, we investigate the traffic shaping function at the edge router in optical packet-switched networks. We propose an optical packet assembly mechanism and discuss its impacts on the traffic characteristics. Our simulation results in...
