摘要
讨论了计算机网络安全领域中容忍入侵、复制技术、群组通信和全序广播之间的内在关联,分析了全序与全序多播的基本概念及属性,研究了重叠组情形下的全序多播及其在容忍入侵的群组通信系统中的实现问题,利用独立的组之间的全序多播协议Totem_Total,提出了一种能在重叠组之间保证全序的多播协议实现方案,给出了详细的伪代码描述并进行了分析.
Internal relationships among intrusion tolerance, replication technology, group communication and total-ordered multicast are discussed. Definitions and properties of total order and total-ordered multicast are analyzed, total-ordered multicast for overlapped groups is discussed and its implementation in intrusion tolerant group communication system is researched. Totem-total which is one of total-ordered multicast protocols without considering overlapped group is selected and a new multicast protocol which can guarantee total order in overlapped groups is presented and is analyzed.
