Optical packet switching (OPS) has been the premier choice for the future Internet. After the effort of OPS researches, however, big challenges still remain unsolved, which include fast tunable wavelength conversion, optical switch fabrics at large dimension, high-speed burst-mode transceiver, random access optical buffers, photonic integration. In this paper, we will elaborate on some technical challenges...
This paper investigates the throughput performance of the d-tree multicast capable optical cross-connect (MC-OXC) by using the separated unicast/multicast splitter-and-delivery (SUM-SaD) switches under synchronous traffic. A d-tree property is introduced to constrain the ability that the MC-OXC and SUM-SaD can accommodate the numbers of light trees. We propose the maximal independent set (MIS) model...
Queuing performance of finite single-wavelength FDL buffer is studied analytically in OPS networks. The evaluation approach can be applied on practical buffer system implementation.
We design and demonstrate a cost-effective 2 times 2 polarization-independent ultra-fast optical switch, which is constructed by a phase modulator based Sagnac interferometer and can support multicasting operation. The measured switching time is ~0.6 ns.
The performance of single-wavelength fiber delay line buffer with finite waiting places is evaluated in this paper. For Poisson arriving packets with arbitrarily distributed lengths, the generating function of delay time distribution can be derived from the quantized delay buffer model. Then queue length distributions, loss probability, and other important performance measures can be figured out....
