【摘要】 针对当前流行覆盖网组播模拟器无法准确为组播系统建模及评测性能的问题,提出一种节点群支持整体代换和多树结构的自相似结构化覆盖网组播(S3M)模型的,设计一个结构化覆盖网组播模拟器,在简化S3M模型结构的基础上为其建立合适的仿真模型。与NICE协议的对比表明,该结构化覆盖网组播模型是有效的。更多还原

【Abstract】 Aiming at the problem that various extending overlay simulator can not afford precise modeling and evaluation of the multicast system, this paper proposes Self-Similar Structured Multicast(S3M) whose nodes group supports unitary substitution and multi-tree structure, designs a scheme of structured application layer multicast model simulator.It sets up an appropriate simulation model for S3M based on the sampling scheme of that multicast model.The simulator can substantiate the validity of the S3M protocol in contrast with NICE protocol.更多还原
