| 摘 要： | 源特定组播技术较好的解决了IP组播中存在的许多问题,但是仍然面临着严重的状态伸缩性问题.源特定聚集组播是解决状态伸缩性问题的一个有效方案.本文在研究源特定聚集组播的基础上,提出了一种新的动态组-树匹配算法,通过减少每个组的匹配次数来提高匹配速度.最后通过实验证明,采用新算法的源特定聚集组播有效的进行了组播状态的聚集,并且提高了聚集速度.

| Abstract: | Source Specific Multicast(SSM) is a viable solution for the current IP multicast applications.However,SSM still confronts the serious state scalability problem.The aggregated source specific multicast(ASSM) is a method of resolving the scalability problem.The ASSM is researched and a new group-tree matching algorithm is proposed.It performed faster aggregations by evaluating fewer trees for each group.The simulations showed that ASSM using the new group-tree matching algorithm had a good performance. |
