【摘要】：随着移动网络IP化进程不断加快，尤其是移动互联网业务的快速发展推动移动通信网络加速IP化背景下，传统传送网平台无法满足多业务传送需求，PTN（Packet Transport Network）网络逐渐成为传送网的主流。同时，为了更好的满足不同客户个性化的服务质量需求，并充分发挥PTN网络的优势，QoS（Quality of Service）技术在传送网中得以应用。本文在介绍QoS技术在PTN网络中实现方式的基础上，结合上海移动传送网以及其承载业务的现状，提出了一套适合上海移动网络特征的PTN网络QoS部署策略。针对2G基站业务、3G基站业务、LTE（Long Term Evolution）业务、大客户专线业务、WLAN（WirelessLocal Area Networks）无线上网业务的OLT（Optical Line Terminal）业务需求特性进行分析，提出合适的QoS参数设置方案，并根据简单的业务模型，对整体部署方案进行分析。通过中兴PTN设备搭建的实验平台进行相关业务测试，，主要包括流分类和队列调度测试，验证了QoS服务策略切实改变业务传送质量性能。进一步构建了基于模糊聚类算法的层次化业务影响评估模型，以了解和把控传输业务的质量。该模型将影响业务质量的指标设为两个层次，通过对一级指标与二级指标设定相应的权重值，经过模糊聚类算法计算可依次得到二级指标评价结果和一级指标评价结果，最终得到业务质量评价的量化值。最后，根据此业务质量影响评估模型，并且结合上海移动PTN网络主要承载业务的情况，对2G基站业务，LTE业务以及WLAN业务进行评估模型的测试分析。通过测试验证，高等级业务如基站业务以及LTE的语音业务质量得到保证与改善，服务等级较低的WLAN业务的业务质量有所下降，QoS策略的部署改变了不同业务的服务等级和传送性能，为不同用户提供了差异化的服务，并且合理分配了网络资源。
[Abstract]:With the rapid development of mobile network IP, especially the rapid development of mobile Internet services, mobile communication network accelerates IP background. Traditional transport network platform can not meet the needs of multi-service transmission. The network has gradually become the mainstream of transport network. At the same time, in order to better meet the needs of different customers' personalized quality of service, the traditional transport network platform can not meet the needs of multi-service transmission. And give full play to the advantage of PTN network QoS quality of Service technology can be applied in the transport network. Based on the introduction of the implementation of QoS technology in PTN network, this paper combines the current situation of Shanghai Mobile Transport Network and its carrying service. This paper puts forward a set of PTN network QoS deployment strategy suitable for the characteristics of Shanghai Mobile Network, analyzes the requirements of OLT(Optical Line terminal service for 2G base station service and 3G base station service, long Term evolution service and WLAN wireless local Area network service. An appropriate QoS parameter setting scheme is proposed, and the overall deployment scheme is analyzed according to the simple business model. Through the experimental platform built by ZTE PTN equipment to carry out related business testing, including flow classification and queue scheduling test, It is verified that QoS service strategy can effectively change the quality of service delivery. Furthermore, a hierarchical service impact assessment model based on fuzzy clustering algorithm is constructed. In order to understand and control the quality of transmission service, the model sets the index which affects the service quality into two levels, and sets the corresponding weight value between the primary index and the second level index. Through the calculation of fuzzy clustering algorithm, the evaluation results of secondary index and first-grade index can be obtained in turn, and the quantitative value of business quality evaluation can be obtained finally. Finally, according to the service quality impact assessment model and combined with the main carrier services of Shanghai Mobile PTN network, the evaluation model of 2G base station service and WLAN service is tested and analyzed. The quality of high grade service such as base station service and voice service of LTE is guaranteed and improved. The service quality of WLAN service with lower service level is decreased. The deployment of QoS policy changes the service level and transmission performance of different services. It provides different services for different users and reasonably allocates network resources.
