    摘要: A circuit-based switching network architecture is still more favorable in optical WDM ring networks in near future. Traffic transferring in a light path can be PtoMP, MPtoP and MPtoMP in the circuit-based switching architecture. PtoMP schemes provide efficient traffic allocation but suffer low wavelength utilization. MPtoP schemes perform well for unicast traffic but not for multicast. MPtoMP schemes, such as Light Trail, provide both unicast and multicast traffic at the same time. MPtoMP should optimize light path creation which is NP hard. This paper discovers the destination number control in a light path is a key parameter. We discuss the effect of the destination number control in a light path and propose simplified MPtoMP network architecture with limited destination number in a light path. This study describes the details of our proposed architecture and traffic transmission rule for unicast and multicast traffic. Due to the properties of our proposed architecture, we expect it to efficiently transfer traffic with high wavelength utilization. Through analyses and numerical results, we can prove proposed architecture has ability to construct efficient and costly broadband access ring networks
