| 1. | Clustering technologies often make use of a fast communication protocol , such as user datagram protocol or multicast protocols
集群技术通常利用快速通信协议，比如用户数据报协议（ user datagram protocol ， udp ）或多播协议。 |
| 2. | Under this circumstance , reliable multicast protocols are better suited for this one - to - many communication than conventional transport layer unicast protocols
在这种情况下，可靠组播比经典的传输层的单播协议更适合这种一对多的通讯。 |
| 3. | However , ip multicast is generally unreliable , disordered and with redundant copies , and there is no reliable multicast protocol designed for multicast - based conference control
但是由于组播传输是不可靠的，所以难以实现基于组播的会议控制。 |
| 4. | The result also shows the second method is better than the first one . secondly , we propose a reliable multicast protocol based on reliable active node ( ranrm )
本文提出了基于可靠主动结点的可靠多播通信协议ranrm ( reliableactivenodereliablemulticast ) 。 |
| 5. | Ieee journal on selected areas in communications , aug . 1999 , 17 : 1380 - 1394 . 8 lee s j , su w , hsu j et al . a performance comparison study of ad hoc wireless multicast protocols
根据以上的观察，本文提出了一个无线自组网络wireless ad hoc networks环境下支持可靠组播的mac协议- “ rmac ” 。 |
| 6. | Journal of computer science and technology , mar . 2004 , 19 : 150 - 157 . 11 don towsley , james kurose , sridhar pingali . a comparison of sender - initiated and receiver - initiated reliable multicast protocols
与这些协议不同的是， rmac引入了busy tone机制来实现可靠组播，从而完全抛弃了使用大量控制帧的方法。 |
| 7. | However , congestion control for multicast protocols has emerged as one of the biggest challenges in the large - scale deployment of multicast applications in the internet . it also is a hard problem and an active research area
但组播技术在internet上进行大规模应用所面临的一个主要挑战就是拥塞控制,组播拥塞控制是一个必须深入研究的问题。 |
| 8. | At the end of the thesis , the author gave the simulation results of several reliable multicast protocols that did some improvement on scalability . we can conclude that hrms makes a better tradeoff between the packet delivery latency and the traffic load
文中最后通过模拟的方法比较了几个改进的可扩展的可靠组播协议，表明可扩展性可靠组播协议hrms具有较短的差错恢复延时与较高的带宽利用率。 |
| 9. | Furthermore , we present a distributed self - adaptive mechanism to construct and maintain the hierarchical structure of hsrm dynamically according to a series of criterions such as distributed , dynamical , fair and so on . at last , the comparisons to several well - known multicast protocols srm , rmtp and tmtp are given
并根据“分布” 、 “动态” 、 “公平” 、 “自治”等原则，设计了hsrm层次化结构的动态构建和维护机制，最后将它与三个经典可靠组播协议进行了比较。 |
| 10. | In order to solve this problem , a reliable multica st communication model for conference control is designed specially . we firstly study the requirements of multicast - based conference control , then analysis the main factors to the performance of reliable multicast . subsequently we present a new reliable multicast protocol named hsrm ( hierarchical scalable and reliable multicast ) according to the receivers " packet loss probabilities
本文从分布式组播会议控制对网络通信的要求出发，在对影响可靠组播性能的因素进行深入分析基础上，融合现有可靠组播协议的优秀思想，提出了一个新的基于接收方丢失报文概率分组的层次化可扩展可靠组播通信模型hsrm ( hierarchicalscalablereliablemulticast ) 。 |
