Reliable application-layer multicast based on hybrid overlay
Bo Sun · Jisuanji gongcheng yu sheji · 2009
Existing application-layer multicast protocols can be categorized into tree-first and mesh-first approaches by the type of overlay they build.A reliable application-layer multicast with an overlay mixing the mesh and tree,called M-THROM is proposed,which is composed of a core mesh and many attached trees for data transmission.It includes error control mechanism and congestion control mecha-nism,designed for large reliable data transmission with a low-delay.Simulation shows that the M-THROM absorbs part merit from the mesh-first protocol and the tree-first protocol,performing well in scalability and low control overhead.
