A novel method for constructing network: Cycle-based Hybrid Switching Optical Networks

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.
