【摘要】：隨著移動網(wǎng)絡IP化進程不斷加快，尤其是移動互聯(lián)網(wǎng)業(yè)務的快速發(fā)展推動移動通信網(wǎng)絡加速IP化背景下，傳統(tǒng)傳送網(wǎng)平臺無法滿足多業(yè)務傳送需求，PTN（Packet Transport Network）網(wǎng)絡逐漸成為傳送網(wǎng)的主流。同時，為了更好的滿足不同客戶個性化的服務質(zhì)量需求，并充分發(fā)揮PTN網(wǎng)絡的優(yōu)勢，QoS（Quality of Service）技術在傳送網(wǎng)中得以應用。 本文在介紹QoS技術在PTN網(wǎng)絡中實現(xiàn)方式的基礎上，結合上海移動傳送網(wǎng)以及其承載業(yè)務的現(xiàn)狀，提出了一套適合上海移動網(wǎng)絡特征的PTN網(wǎng)絡QoS部署策略。針對2G基站業(yè)務、3G基站業(yè)務、LTE（Long Term Evolution）業(yè)務、大客戶專線業(yè)務、WLAN（WirelessLocal Area Networks）無線上網(wǎng)業(yè)務的OLT（Optical Line Terminal）業(yè)務需求特性進行分析，提出合適的QoS參數(shù)設置方案，并根據(jù)簡單的業(yè)務模型，對整體部署方案進行分析。 通過中興PTN設備搭建的實驗平臺進行相關業(yè)務測試，，主要包括流分類和隊列調(diào)度測試，驗證了QoS服務策略切實改變業(yè)務傳送質(zhì)量性能。進一步構建了基于模糊聚類算法的層次化業(yè)務影響評估模型，以了解和把控傳輸業(yè)務的質(zhì)量。該模型將影響業(yè)務質(zhì)量的指標設為兩個層次，通過對一級指標與二級指標設定相應的權重值，經(jīng)過模糊聚類算法計算可依次得到二級指標評價結果和一級指標評價結果，最終得到業(yè)務質(zhì)量評價的量化值。 最后，根據(jù)此業(yè)務質(zhì)量影響評估模型，并且結合上海移動PTN網(wǎng)絡主要承載業(yè)務的情況，對2G基站業(yè)務，LTE業(yè)務以及WLAN業(yè)務進行評估模型的測試分析。通過測試驗證，高等級業(yè)務如基站業(yè)務以及LTE的語音業(yè)務質(zhì)量得到保證與改善，服務等級較低的WLAN業(yè)務的業(yè)務質(zhì)量有所下降，QoS策略的部署改變了不同業(yè)務的服務等級和傳送性能，為不同用戶提供了差異化的服務，并且合理分配了網(wǎng)絡資源。
[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.
