【摘要】：隨著互聯(lián)網(wǎng)技術的廣泛應用,各種業(yè)務的發(fā)展方向是IP化。為了實現(xiàn)寬帶IP業(yè)務靈活調(diào)度,提供靈活的網(wǎng)絡保護和恢復機制,傳輸網(wǎng)不僅要提供高容量帶寬,以滿足寬帶業(yè)務需求,更需要提供功能良好的端到端網(wǎng)絡運行與操作管理(OAM)能力。OTN設備結合了SDH與WDM的優(yōu)勢,OTN有強大的OAM功能,可以實現(xiàn)大顆粒業(yè)務的靈活調(diào)度和保護,解決了SDH設備處理大顆粒業(yè)務效率低下的問題,OTN也可以提供超大容量的帶寬傳送。未來,OTN設備會引入更高的速率接口,目前100G OTN以及商用部署,中國移動已經(jīng)在進行400G OTN設備測試。關于400G標準還沒有成熟,存在多種技術選擇,預計不久的將來會實現(xiàn)標準化。 隨著OTN設備的大規(guī)模部署,OTN網(wǎng)絡與其他網(wǎng)絡的聯(lián)合組網(wǎng)越來越重要。OTN與現(xiàn)有SDH/WDM網(wǎng)絡聯(lián)合組網(wǎng),OTN與路由器IP承載網(wǎng)絡聯(lián)合組網(wǎng)以及多廠家互聯(lián)互通成為研究的重點。OTN與SDH、IP路由器網(wǎng)絡聯(lián)合組網(wǎng)可以更好的優(yōu)化組網(wǎng)結構,提高網(wǎng)絡帶寬利用率。本文的主要研究內(nèi)容及成果如下： 研究不同廠家OTN設備與SDH設備業(yè)務互聯(lián)互通主要問題及關鍵技術,根據(jù)業(yè)務互聯(lián)互通存在的問題構建測試實驗環(huán)境,對測試數(shù)據(jù)進行分析,提出業(yè)務互聯(lián)互通解決方案。根據(jù)鐵路骨干光傳送網(wǎng)平滑升級改造實際需求,提出OTN與SDH三種組網(wǎng)架構,并構建實驗環(huán)境進行測試驗證,對測試數(shù)據(jù)進行分析比較,針對不同網(wǎng)絡平滑升級改造環(huán)境給出相應的解決方案。對目前鐵路時鐘時間同步網(wǎng)存在的問題及缺陷進行分析研究,并對同一廠家及不同廠家OTN與SDH設備1588V2時鐘組網(wǎng)方案進行研究,分別給出相應的1588V2組網(wǎng)解決方案。 對不同廠家OTN與路由器業(yè)務互聯(lián)互通主要問題進行研究,并構建對應的實驗環(huán)境進行測試驗證,提出業(yè)務互聯(lián)互通解決方案。在OTN與路由器保護協(xié)調(diào)技術及聯(lián)合組網(wǎng)中,針對OTN與路由器端到端OAM開銷協(xié)調(diào)處理以及OTN與路由器保護協(xié)調(diào)的問題,構建相應測試環(huán)境,對測試數(shù)據(jù)進行分析研究,給出了保護協(xié)調(diào)的解決方案。
[Abstract]:With the wide application of Internet technology, the development direction of various services is IP. In order to achieve flexible scheduling of broadband IP services and provide flexible network protection and recovery mechanism, transmission networks should not only provide high capacity bandwidth to meet the requirements of broadband services. It is also necessary to provide a well-functioning end-to-end network operation and operation management (OAM) capability. OTN equipment combines the advantages of SDH and WDM. OTN has a powerful OAM function and can achieve flexible scheduling and protection of large granular services. It solves the problem that SDH equipment is inefficient in dealing with large particle traffic. OTN can also provide very large capacity bandwidth transmission. In the future, the OTN device will introduce a higher rate interface, currently 100G OTN and commercial deployment, and China Mobile is already testing 400G OTN devices. The 400 G standard is not yet mature, there are a variety of technical options, is expected to be standardized in the near future. With the large-scale deployment of OTN equipment, it is becoming more and more important to combine OTN network with other networks. OTN and existing SDH/WDM network, OTN and router IP bearer network, as well as multi-vendor interconnection become the focus of research. OTN and SDHN IP router network can better optimize the network structure. Improve the utilization of network bandwidth. The main contents and achievements of this paper are as follows: the main problems and key technologies of business interconnection between OTN equipment and SDH equipment from different manufacturers are studied, and the test environment is constructed according to the problems existing in service interconnection. The test data are analyzed and the solution of service interconnection is put forward. According to the actual requirement of smooth upgrading and upgrading of railway backbone optical transport network, three kinds of network architecture, OTN and SDH, are put forward, and the experimental environment is built to test and verify, and the test data are analyzed and compared.
