| 1. | The body of the igmp datagram also includes the class d group address
Igmp的资料包亦会包含有群播群组位址的资讯。 |
| 2. | The client sends an igmp join message to its designated multicast router
客户端会传送igmp加入群组讯息到指定的群播路由器。 |
| 3. | Ip multicast traffic transmitted from the server is now distributed via the designated router to the client ' s subnet
此时ip群播流量经由被指定的路由器从伺服器传送至客户端所在网段。 |
| 4. | Tree construction is a commonly used approach in solving the multicast and group multicast routing problem
本文主要研究多播和群播路由算法，即建立满足各种业务服务质量需求的多播树。 |
| 5. | Simulation results show that our algorithms performed better in terms of cost compared with gtm algorithm and have the same time complexity ( p3n2 )
对于带有多个约束的群播路由算法，由于其采用改进了的成本函数，算法的时间复杂度并没有增加，也为( p3n2 ) 。 |
| 6. | The router logs the join message and uses pim or another multicast routing protocol to add this segment to the multicast distribution tree ( if it is not already attached )
路由器会记录此加入的讯息并且使用pim或另一种群播路由协定加入此区段到群播的分布树中(如果尚未沟通过) 。 |
| 7. | Thirdly , the group multicast routing problem with bandwidth constrained is studied , three heuristic algorithms for group multicast routing are presented . the former two group multicast algorithms are the improvement of gtm algorithm
此外，本论文还研究了有带宽预留机制的群播路由问题，给出了两种有带宽约束的群播路由算法和一种带有多个约束的群播路由算法。 |
| 8. | Multicast routing is a network - layer function that constructs paths along which data pachets from a source are distributed to reach many , but not all , destinations in a communication network , a fundamental issue in multicast communication is how to determine an efficient message route ( multicast routing )
网络中的通信由单一的两点间的通信向多点间的通信发展，因此对多播和群播（是多播的一种推广）技术的研究也成为网络通信领域中的一个重要研究课题。多播是一个源节点将同一信息传送到多个目的节点(但不是所有节点)的通信方式。 |
| 9. | " distance learning " as defined in these rules includes such techniques as synchronous ( multicasting ) distance learning , asynchronous distance learning , and combinations of the two techniques , and applies to courses offered by individual schools or through reciprocal agreements , in either degree programs or credit programs
本规范所定远距教学，其方式包括同步（即时群播）远距教学、非同步远距教学及同步与非同步混合式远距教学，并适用于各校或学校相互间授课之学位班或学分班。 |
