Test electronics for a multi-gbps optical packet Switching Network
2006 8th Electronics Packaging Technology Conference, 2006Co-Authors: C E Gray, David C. Keezer, Odile Liboiron-ladouceur, K. BergmanAbstract:In this paper we present the design and performance characteristics for a custom test system developed to characterize a DWDM optically-routed packet Switching Network (called "data vortex"). The existing demonstration system supports aggregate data rates of 20 to 32 Gbps using 8 optical payload wavelengths each running at 2.5-4.0 Gbps. Several other optical wavelengths are used to transmit a source-synchronous clock, frame, and eight routing address bits. All of the signals are transmitted in a parallel 25.6ns optical burst (packet). Switching nodes within the data vortex decode the optical routing bits in real-time and direct the packet to its intended destination. Unlike traditional Switching Networks, the data vortex nodes are switched "on the fly" by the routing information contained within the optical packet itself (rather than by a central control system).

Dynamic power considerations in a complete 12 /spl times/ 12 optical packet Switching Network
IEEE Photonics Technology Letters, 2005Co-Authors: B.a. Small, T. Kato, K. BergmanAbstract:The dynamic optical power characteristics of an implemented 12-port optical packet Switching Network are measured for multiple-wavelength packets with 16 payload wavelengths and five routing header wavelengths. The system demonstrates an average dynamic optical power range of approximately 6.7 dB at the 10/sup -12/ bit-error-rate (BER) threshold, and 8.2 dB at 10/sup -9/ BER. These measurements which investigate how the system affects the encoded optical packets are discussed as metrics for Network scalability and robustness.

leader following consensus of multiple uncertain euler lagrange systems under Switching Network topology
International Journal of General Systems, 2014Co-Authors: Jie HuangAbstract:In recent years, the leader-following consensus problem for multiple uncertain Euler–Lagrange systems has been studied under some restrictive assumptions on the Network topology. In this paper, we further study the same problem under Switching Network topology. We propose a distributed adaptive control law that can solve the problem under a Switching Network satisfying jointly connected condition. Under this condition, our results do not require the Network to be undirected and allow the Network to be disconnected at any time instant. Moreover, by introducing an exosystem to generate various reference signals, our control law can handle a class of reference signals such as sinusoidal signals with arbitrary amplitudes and initial phases or ramp signals with arbitrary slopes.

two consensus problems for discrete time multi agent systems with Switching Network topology
Automatica, 2012Co-Authors: Youfeng Su, Jie HuangAbstract:In this paper, we study both the leaderless consensus problem and the leader-following consensus problem for linear discrete-time multi-agent systems under Switching Network topology. Under the assumption that the system matrix is marginally stable, we show that these two consensus problems can be solved via the state feedback protocols, provided that the dynamic graph is jointly connected. Our result will contain several existing results as special cases. The proof is based on the stability analysis of a class of linear discrete-time switched systems which may have some independent interest.

Cooperative Output Regulation With Application to Multi-Agent Consensus Under Switching Network
IEEE Transactions on Systems Man and Cybernetics Part B (Cybernetics), 2012Co-Authors: Youfeng Su, Jie HuangAbstract:In this paper, we consider the cooperative output regulation of linear multi-agent systems under Switching Network. The problem can be viewed as a generalization of the leader-following consensus problem of multi-agent systems. Due to the limited information exchanges of different subsystems, the problem cannot be solved by the decentralized approach and is not allowed to be solved by the centralized control. By devising a distributed observer Network, we can solve the problem by both dynamic state feedback control and dynamic measurement output feedback control. As an application of our main result, we show that a special case of our results leads to the solution of the leader-following consensus problem of linear multi-agent systems.

Reduction of crosstalk in a photonic space division Switching Network employing traveling wave amplifiers and automatic power control
IEEE Photonics Technology Letters, 1992Co-Authors: C. Burke, M. Fujiwara, T. ShiragakiAbstract:Because of optical loss variations through different connection paths in LiNbO/sub 3/ switch matrices, optical crosstalk in a photonic space division Switching Network will be enhanced. This work theoretically investigates the power penalty due to optical crosstalk in a 128 line photonic space division Switching Network which employs loss compensating semiconductor amplifiers, and experimentally confirms the suppression of power penalty by employing an automatic power control (APC) scheme. Experiments have shown the successful operation of an APC system in keeping a constant optical power level throughout the system and the negligible power penalty values obtained agree with a calculated model.
