“…Note that we just try to deal with physical topologies with Hamilton cycles. The physical topologies without Hamilton Cycles will be left for future study, in such cases, we could establish multi-cycles to cover the topology as in [14].…”

“…We assume link is bidirectional, each physical link has 8 wavelengths with transmission rate 10Gbps per wavelength, and the widely used Poisson traffic model is employed. Traffic load varies from 1 to 10 (Erlang), and the same traffic pattern as in [14] is used. IP packet length is 1250 Bytes, each burst has 1000 IP packets at most.…”

In this paper, we propose a novel hybrid optical network design method, Cycle-based Hybrid Switching Optical Networks (CHSON), to efficiently support bursty traffic patterns of current networks. CHSON integrates highly efficient transportation of Optical Circuit Switching with statistical multiplexing of Optical Burst Switching. CHSON could not only reduce the strain on packet forwarding of traditional point to point WDM solutions to relieve electronic bottleneck, but also accommodate bursty traffic and achieve better bandwidth efficiency than all-optical wavelength switching networks (i.e., OCS networks). We first introduce the overall architecture of CHSON as well as virtual topology design involved. Then we illustrate node design and implementation of CHSON. Our simulation results show that the packet loss ratio of CHSON is much lower than that of traditional OCS networks, and CHSON outperforms OBS networks significantly in both packet loss ratio and average delay.I.

Abstract-We consider the issue of protection in very large networks displaying randomness in topology. We employ random graph models to describe such networks, and obtain probabilistic bounds on several parameters related to reliability. In particular, we take the case of random regular networks for simplicity and consider the length of primary and backup paths in terms of the number of hops. First, for a randomly picked pair of nodes, we derive a lower bound on the average distance between the pair and discuss the tightness of the bound. In addition, noting that primary and protection paths form cycles, we obtain a lower bound on the average length of the shortest cycle around the pair. Finally, we show that the protected connections of a given maximum finite length are rare. We then generalize our network model so that different degrees are allowed according to some arbitrary distribution, and show that the second moment of degree over the first moment is an important shorthand for behavior of a network. Notably, we show that most of the results in regular networks carry over with minor modifications, which significantly broadens the scope of networks to which our approach applies. We present as an example the case of networks with a power-law degree distribution.
