Optical Burst Switching proposes a future-proof alternative to the current electronic switching in the backbone. The involved optical buffers are implemented with a set of Fiber Delay Lines, and suffer serious performance loss, when compared to RAM. Various existing models trace this loss, but either lack generality, accuracy, or effectiveness. The optical buffer model we constructed is valid f...

This paper is devoted to the study of multi-agent consensus with a time-varying reference state in directed networks with both switching topology and constant time delay. Stability analysis is performed based on a proposed Lyapunov–Krasovskii function. Sufficient conditions based on linear matrix inequalities (LMIs) are given to guarantee multi-agent consensus on a time-vary reference state und...

Banyan networks are being proposed for interconnecting memory and processor modules in multiprocessor systems as well as for packet switching in communication networks. This paper describes an analysis of the performance of a packet switch based on a single-buffered Banyan network. A model of a single-buffered Banyan network provides results on the throughput, delay, and internal blocking. Resu...

AbstmctHigh-performance wide-area networks are required to interconnect clusters of computers connected by local area and metropolitan area networks. Optical fiber technology provides long distance channels in the multigigabit per second range. The challenge is to provide switching nodes that handle these data rates with minimum delay, and at a reasonable cost. In this paper, we describe a pack...

In this paper we discuss stochastic differential delay equations with Markovian switching. Such an equation can be regarded as the result of several stochastic differential delay equations switching from one to the others according to the movement of a Markov chain. The main aim of this paper is to investigate the robustness of exponential stability of the equations. The criteria obtained in th...

Based on the calculus of variation, an optimal switching control problem for switched autonomous systems with time-delay is studied. The switching times in a sequence of fixed vector fields are the sole control variables and the subsystems do not require a refractory period, which can bring more generality. The analytic expressions for the partial derivatives of the given performance cost with ...

The problem of optimal switching of a multi-mode time delay system is considered. The class of multi-mode systems consists of systems where the control variables are the switching times in a sequence of fixed vector fields. We assume that the systems considered all have a refractory period, in the sense that once an action is taken, it takes a non-infinitesimal amount of time before a subsequen...

In this paper, the design of switching rule for exponential stability of a class of uncertain switched systems with delays is studied. The systems to be considered are linear and the state delays are time-varying. Based on Lyapunov functional and average dwell time approach, condition on the derivative of time-delay functions are not need to design switching rule for the exponential stability o...

Multi-context (MC) FPGAs have multiple memory bits per configuration bit forming configuration planes for fast switching between contexts. Large amount of memory causes significant overhead in area and power consumption. This paper presents two key technologies. The first is a floating-gate-MOS functional pass gate that merges storage and switching functions area-efficiently. The second is the ...
