【摘要】：隨著移動(dòng)網(wǎng)絡(luò)IP化進(jìn)程不斷加快，尤其是移動(dòng)互聯(lián)網(wǎng)業(yè)務(wù)的快速發(fā)展推動(dòng)移動(dòng)通信網(wǎng)絡(luò)加速IP化背景下，傳統(tǒng)傳送網(wǎng)平臺(tái)無法滿足多業(yè)務(wù)傳送需求，PTN（Packet Transport Network）網(wǎng)絡(luò)逐漸成為傳送網(wǎng)的主流。同時(shí)，為了更好的滿足不同客戶個(gè)性化的服務(wù)質(zhì)量需求，并充分發(fā)揮PTN網(wǎng)絡(luò)的優(yōu)勢，QoS（Quality of Service）技術(shù)在傳送網(wǎng)中得以應(yīng)用。 本文在介紹QoS技術(shù)在PTN網(wǎng)絡(luò)中實(shí)現(xiàn)方式的基礎(chǔ)上，結(jié)合上海移動(dòng)傳送網(wǎng)以及其承載業(yè)務(wù)的現(xiàn)狀，提出了一套適合上海移動(dòng)網(wǎng)絡(luò)特征的PTN網(wǎng)絡(luò)QoS部署策略。針對(duì)2G基站業(yè)務(wù)、3G基站業(yè)務(wù)、LTE（Long Term Evolution）業(yè)務(wù)、大客戶專線業(yè)務(wù)、WLAN（WirelessLocal Area Networks）無線上網(wǎng)業(yè)務(wù)的OLT（Optical Line Terminal）業(yè)務(wù)需求特性進(jìn)行分析，提出合適的QoS參數(shù)設(shè)置方案，并根據(jù)簡單的業(yè)務(wù)模型，對(duì)整體部署方案進(jìn)行分析。 通過中興PTN設(shè)備搭建的實(shí)驗(yàn)平臺(tái)進(jìn)行相關(guān)業(yè)務(wù)測試，，主要包括流分類和隊(duì)列調(diào)度測試，驗(yàn)證了QoS服務(wù)策略切實(shí)改變業(yè)務(wù)傳送質(zhì)量性能。進(jìn)一步構(gòu)建了基于模糊聚類算法的層次化業(yè)務(wù)影響評(píng)估模型，以了解和把控傳輸業(yè)務(wù)的質(zhì)量。該模型將影響業(yè)務(wù)質(zhì)量的指標(biāo)設(shè)為兩個(gè)層次，通過對(duì)一級(jí)指標(biāo)與二級(jí)指標(biāo)設(shè)定相應(yīng)的權(quán)重值，經(jīng)過模糊聚類算法計(jì)算可依次得到二級(jí)指標(biāo)評(píng)價(jià)結(jié)果和一級(jí)指標(biāo)評(píng)價(jià)結(jié)果，最終得到業(yè)務(wù)質(zhì)量評(píng)價(jià)的量化值。 最后，根據(jù)此業(yè)務(wù)質(zhì)量影響評(píng)估模型，并且結(jié)合上海移動(dòng)PTN網(wǎng)絡(luò)主要承載業(yè)務(wù)的情況，對(duì)2G基站業(yè)務(wù)，LTE業(yè)務(wù)以及WLAN業(yè)務(wù)進(jìn)行評(píng)估模型的測試分析。通過測試驗(yàn)證，高等級(jí)業(yè)務(wù)如基站業(yè)務(wù)以及LTE的語音業(yè)務(wù)質(zhì)量得到保證與改善，服務(wù)等級(jí)較低的WLAN業(yè)務(wù)的業(yè)務(wù)質(zhì)量有所下降，QoS策略的部署改變了不同業(yè)務(wù)的服務(wù)等級(jí)和傳送性能，為不同用戶提供了差異化的服務(wù)，并且合理分配了網(wǎng)絡(luò)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.
