Opis:: Performance evaluation of the multiple output queueing (MOQ) switch recently proposed by us is discussed in this paper. In the MOQ switch both the switch fabric and buffers can operate at the same speed as input and output ports. This solution does not need any speedup in the switch fabric as well as any matching algorithms between inputs and outputs. In this paper new performance measures for the proposed MOQ switch are evaluated. The simulation studies have been carried out for switches with different buffer arrangements strategy and of capacity 2×2, 4×4, 8×8, 16×16 and 32×32, and under selected traffic patterns. The simulations results are also compared with OQ switches of the same sizes.

Opis:: This paper is devoted to evaluating the performance of Space-Memory-Memory (SMM) Clos-network switches under a packet dispatching scheme employing static connection patterns, referred to as Static Dispatching (SD). The control algorithm with static connection patterns can be easily implemented in the SMM fabric due to bufferless switches in the first stage. Stability is one of the very important performance factors of packet switching nodes. In general, a switch is stable for a particular arrival process if the expected length of the packet queues does not increase without limitation. To prove the stability of the SMM Clos-network switches considered under the SD packet dispatching scheme the discrete Markov chain model of the switch is used and Foster’s criteria to extend Lyapunov’s second (direct) method of stability investigation of discrete time stochastic systems are used. The results of simulation experiments, in terms of average cell delay and packet queue lengths, are shown as well.

Opis:: In this paper the new packet switch architecture with multiple output queuing (MOQ) is proposed. In this architecture the nonblocking switch fabric, which has the capacity of N _N2 N2, and output buffers arranged into N separate queues for each output, are applied. Each of N queues in one output port stores packets directed to this output only from one input. Both switch fabric and buffers can operate at the same speed as input and output ports. This solution does not need any speedup in the switch fabric as well as arbitration logic for taking decisions which packets from inputs will be transferred to outputs. Two possible switch fabric structures are considered: the centralized structure with the switch fabric located on one or several separate boards, and distributed structure with the switch fabric distributed over line cards. Buffer arrangements as separate queues with independent write pointers or as a memory bank with one pointer are also discussed. The mean cell delay and cell loss probability as performance measures for the proposed switch architecture are evaluated and compared with performance of OQ architecture and VOQ architecture. The hardware complexity of OQ, VOQ and presented MOQ are also compared. We conclude that hardware complexity of proposed switch is very similar to VOQ switch but its performance is comparable to OQ switch.

Opis:: Scalability of packet switched cross-connects that utilize all-optical signal processing is a crucial issue that eventually determines the future role of photonic signal processing in optical networks. After reviewing several labeling techniques, we discuss label stacking and label swapping techniques and their benefits for scalable optical packet switched nodes. All-optical devices for implementing the packet switch based on the labeling techniques will be described. Finally, we present a 1×4 all-optical packet switch based on label swapping technique that utilizes a scalable and asynchronous label processor and label rewriter. Error-free operation indicates a potential utilization of the swapping technique in a multihop packet-switched network.
