摘　　要：针对警用专网组播中的协议框架问题,提出了采用稀疏模式下的特定源组播协议模型(PIM-SSM)的方案并分析了其合理性,经过仿真验证了该模式能够实现指定信源指定组播组的数据通信,证明其对警用专网中组播机制的适用性。最后针对日益严重的DoS攻击问题,提出了一种基于报文流量的安全防护机制。According to the protocol framework of the private police network, the scheme of PIM-SSM protocol model under the sparse mode was adopted and its feasibility was analyzed. Simulations verified the mode can achieve the data communication of the specific multicast group from the designated source and validated its applicability to the multicast in the private police network. In addition, in view of the increasingly severe DoS attacks, a security protection mechanism based on the packet traffic was proposed.
