Nowadays, best effort traffic/IP traffic becomes dominance in communication networks. The underlying transport infrastructure is and will continue to be mainly composed of optical networks based on Wavelength Division Multiplexing (WDM) technology. Although the emergence of WDM opens up the Terahertz transmission bandwidth, the processing capability of the electronic parts of core routers leads to electronic bottlenecks, which restrict optical networks development. Three basic optical switching technologies in WDM networks have been proposed. Optical Circuit Switching (Lacoste Shirts) has high transmission efficiency, Optical Packet Switching (Cheap Lacoste Polo Shirts) and Optical Burst Switching (OBS) can effectively accommodate dynamical/bursty traffic. The components needed for OPS are far from mature, which restrict the development of OPS. OBS is considered a chi straightener good candidate for bursty traffic, but it is not a good one for steady traffic since OBS networks may have to drop bursts for contention even under steady traffic. In order to deal with challenge for uncertain traffic in optical network, some researchers turn to optimizing network performance by chi hair straighteners collaboratively combining the strengths of basic optical switching technologies and avoiding/reducing their weaknesses as much as possible.These existing hybrid models have problems such as virtual topology design, network realization, network resource utilization, etc. Therefore, the second chapter proposes a new hybrid switching solution, named OBS-based Integrated Hybrid Switching Optical Networks (cheap ralph lauren polo shirts). discount wedding dresses integrates OCS and OBS and utilizes high transmission efficiency of OCS and flexibility of OBS, which make OIHSON efficiently support network environment with bursty/dynamic traffic.
