  • Publication number: 20120054282
    Abstract: Architecture and method of hybrid P2P/client-server for data transmission involve using a P2P grouping method to determine the data transmission mode being a P2P mode or a client-server mode by an original source, for a plurality of peers connected to the original source. The original source further divides the plurality of peers into a P2P group and a client-server group, and dynamically determines the respective number of peers and the upstream bandwidth for the two groups. Thereby, during a data transmission procedure, it may achieve a performance balance among the propagation delay, restriction of upstream bandwidth for data sources, network throughput and system loading.
