| 摘 要： | 提出并分析了基于光纤网络的IP电话系统，针对IP电话网中的时延，抖动，数据包丢失等关键问题分别进行分析。找出了取消网关，路由器和采用光纤化等解决方法，比较基于H．232协议的IP电话与基于SIP协议的光纤IP电话系统，发现利用光纤网能很好补偿时延和改善数据包丢失等问题，提高系统的抗干扰能力，使IP电话系统的性能得到很大提高，采用排队论进行了流量分析，证明以上方法是有效的。

| Abstract: | In this paper, IP telephone system based on optical fiber network is introduced and investigated. Based on analysis on time delay, joggling and losses of data package, the solution is presented, for example canceAlation of gateway and router and utilization of optical fiber. Compared with IP telephone based on H.232 protocol, the fiber- optic IP telephone system based on STP protocol greatly improves the performance of IP telephone system because the use of optical fiber network can compensates time delay and reduces losses of data package and jamming- rejection capability of system. Applied in traffic analysis, queueing theory proves the above solution availability. |
