We propose a novel Load Weighted Scheduling Algorithm (LWSA) to improve the packet aggregation performance for randomly-varied traffic patterns. Simulation results show that the LWSA provides higher utilization than the basic round-robin scheduling algorithm and retains the traffic pattern from IP network to OPS network quite well.
This paper investigates the “Blind Zone” of electronic packet header processing in the core routers of asynchronous optical packet switching network. Simulation shows that the “Blind Zone” has significant impact on packet loss which is also influenced by the arrival interval and the packet length.
We design and demonstrate a cost-effective 2times2 ultrafast multicast-capable optical switch (MCOS) based on a Sagnac interferometer. The Sagnac interferometer is composed of a LiNbO3 phase modulator (PM) with two polarization-maintaining pigtail fibers and a 3-dB polarization-maintaining coupler. The MCOS works at three states: cross, bar, and multicast, in the entire C-band (1525-1565 nm) by controlling...
