摘要: 针对复杂多变的移动组播环境,从整体上提出了一种基于优先级的报文管理机制(PDMM)。对不同类型的报文赋以不同的优先级别,提出了一种基于层次结构的自适应移动组播路由协议(AMMPH),在子网内采用隧道机制、子网间采用远程签署和隧道机制相结合的组播路由协议,保证了报文的可靠高效传输,并在寻求最短转发路径和减少组播树重构开销间取得了较好的平衡。

Abstract: In order to adapt to the complicated mobile multicast environment, this paper brings forward a priority-based datagram management mechanism which endues different datagram with different priorities, and advances an adaptive mobile multicast protocol for the network based on the hierarchical architecture. Adopt bi-directional tunneling mechanism in the subnet and adopt the integration of bi-directional tunneling and remote subscription in the region. The protocol can deliver the datagram reliably and efficiently, and it also can get a balance between the shortest delivery route and the reduction of multicast tree’s reconstruction cost.
