—This paper presents and analyzes a high-performance , robust, and scalable scheduling algorithm for input-queued switches called distributed sequential allocation (DISA). In contrast to pointer-based arbitration schemes, the proposed algorithm is based on a synchronized output reservation process, whereby each input selects a designated output while taking(More)
SUMMARY Future high-speed switches and routers will be expected to support a large number of ports at high line rates carrying traffic with diverse statistical properties. Accordingly, scheduling mechanisms will be required to handle Tbit/sec ag-gregated capacity while providing quality of service (QoS) guarantees. In this paper a novel high-capacity(More)
— Virtual output queueing is commonly deployed as a buffering technique in high-performance input-queued switch architectures. This paper presents analysis for discrete-time virtual output queued switches with incoming traffic governed by a uniformly distributed Markov modulated ON/OFF process, and geometrically distributed service times. We utilize the(More)

Contrary to pointer-based arbitration schemes, the algorithm proposed is based on a synchronized channel reservation cycle whereby each input selects a designated output,(More)
—The nonlinear effects of Mach–Zehnder modulator (MZM) and self phase modulation (SPM), in optical orthogonal frequency division multiplexing (OFDM) under the presence of high peak power is studied. A full coherent optical communication system is presented and analyzed. Standard method to reduce the peak to average power ratio (PAPR) values combined with(More)
