【摘要】：随着光接入的移动网络宽带化和IP化的发展,全IP已经成为了融合化、全业务承载网的基石。IPRAN基于IP技术来做移动网络的承载,并且参考传统SDH(同步光网络)的一些优势,在安全方面做了一些增强,使得其在光网络的灵活性、扩展性以及安全性方面有了一定的优势,伴随着LTE进入运营商的网络,IP RAN迎来了机遇发展期。LTE网络对承载网络的IP方面提出了更高的要求,相对于点到点传输类解决方案,IP RAN具有综合化、融合化承载的优势。根据上述情况,中国联通网络技术研究院根据集团统一部署,积极进行IPRAN的设备性能测试,本论文来源于该项目。本文首先从运营商网络的整体发展趋势入手,介绍了基于光网络的IPRAN的发展背景以及技术体系架构,并详细对比其与PTN、MSTP等技术的实验原理、相对优势以及关键技术。之后本文详细介绍了 IPRAN的相关技术,如MPLS、VLL、VPLS等,对三层光网络结构进行了概述,并且对联通网研院测试时所使用的测试仪表的测试分类和指标进行了阐明,再后,按照测试拓扑图连接测试设备,利用测试仪表对厂商设备进行模拟光网络环境下单机设备以及互通测试。最后,结合测试过程中的具体情况对测试结果进行比对剖判,总结出设备存在的问题以及不同厂商设备在光通信性能表现上的差异性,再根据本次测试分析对下次测试进行优化和展望。
[Abstract]:With the development of broadband and IP in the mobile network of optical access, all IP has become the integration. The cornerstone of the whole service carrying network. IPRAN is based on IP technology to carry the mobile network, and reference some advantages of traditional SDH (synchronous Optical Network). Some security enhancements have been made to give it some advantages in terms of flexibility, scalability and security of optical networks. With LTE coming into the network of operators, IP ran meets the opportunity development period. LTE network puts forward higher requirements for the IP aspect of the carrying network. Compared with the point-to-point transmission type solution, IP ran has the advantages of integration and integration of carrying capacity. According to the above situation, the China Unicom Network Technology Research Institute carries out the equipment performance test of IPRAN according to the unified deployment of the group. This paper first introduces the development background and technical architecture of IPRAN based on optical network, and compares the experimental principle, comparative advantage and key technology of IPRAN with PTNMSTP in detail. Then this paper introduces the related technologies of IPRAN in detail, such as MPLSN VLLLN VPLS and so on, summarizes the three-layer optical network structure, and expounds the test classification and index of the test instruments used in the test of China Unicom Research Institute. According to the test topology diagram, the test equipment is connected, and the testing instrument is used to test the manufacturer equipment under the environment of analog optical network and interworking. Finally, according to the specific conditions in the testing process, the test results are compared and judged, and the problems existing in the equipment and the differences in the performance of different manufacturers in optical communication performance are summarized. According to this test analysis, the next test will be optimized and prospected.
