【摘要】：以太網(wǎng)誕生之初主要用于局域網(wǎng)。由于局域網(wǎng)本身具有較好的穩(wěn)定性及可靠性，以太網(wǎng)在設計之初未太過多的考慮管理及維護機制。而隨著技術的發(fā)展，以太網(wǎng)沒有可靠OAM機制的問題不斷凸顯，制約著以太網(wǎng)在更大范圍中的應用。針對于以太網(wǎng)OAM的迫切需求，國際標準化組織IEEE和ITU-T分別制定并公布了802.1ag協(xié)議和Y.1731協(xié)議。由以上兩個協(xié)議構成了完整的電信級以太網(wǎng)OAM協(xié)議簇。 本文以全球第二大企業(yè)級交換機設備商H3C通信公司的Comware V7操作系統(tǒng)中CFD協(xié)議功能模塊為藍本進行闡述。CFD協(xié)議模塊基于IEEE802.1ag和ITU-TY.1731兩份協(xié)議，主要提供企業(yè)級及電信級的基于VLAN的二層鏈路端到端OAM功能。作者在2012年至2013年于H3C公司實習11個月，完整的參與了CFD模塊的開發(fā)工作，主要負責其內部以太網(wǎng)告警抑制功能、快速檢測功能及性能測試功能的開發(fā)工作。本文以模塊中最為重要的快速檢測及以太網(wǎng)告警抑制為重點進行論述，對其模塊架構、業(yè)務流程、處理實現(xiàn)進行詳細闡述，并在最后進行系統(tǒng)測試來檢驗模塊的功能。作者在項目開發(fā)中提出并實現(xiàn)了以太網(wǎng)告警抑制的分布式均衡處理方法，極大的減少了系統(tǒng)實現(xiàn)以太網(wǎng)告警抑制所需要的資源，并且提高了以太網(wǎng)告警抑制處理的速度。 CFD模塊實現(xiàn)后，向企業(yè)級及電信級網(wǎng)絡提供快速且高可靠性的網(wǎng)絡連通性監(jiān)測，補充了以太網(wǎng)在OAM機制的缺失，，從而為以太網(wǎng)在電信級網(wǎng)絡的應用提供了保證。
[Abstract]:Ethernet is mainly used in local area network at the beginning of its birth. Because the LAN itself has good stability and reliability, Ethernet has not too much consideration of management and maintenance mechanism at the beginning of the design. With the development of technology, the problem of Ethernet without reliable OAM mechanism is constantly highlighted, and the application of Ethernet in a wider range is made. In the urgent need of Ethernet OAM, the international standardization organization IEEE and ITU-T have formulated and announced the 802.1ag protocol and the Y.1731 protocol respectively. The whole telecom level Ethernet OAM protocol cluster is formed by the above two protocols.
In this paper, the CFD protocol function module in the Comware V7 operating system of H3C communications company H3C communications company, the world's largest enterprise, is described as the blueprint of the CFD protocol function module. The.CFD protocol module is based on the IEEE802.1ag and ITU-TY.1731 protocol based on the two layer link end to end OAM function based on the VLAN based VLAN. The author is from 2012 to 2013. After 11 months of internship in H3C, the company was fully involved in the development of the CFD module, mainly responsible for its internal Ethernet alarm suppression function, rapid detection function and performance testing function development. This paper focuses on the most important rapid detection and Ethernet alarm suppression in the module, and its module architecture and business process. In the project development, the author puts forward and realizes the distributed equilibrium processing method of Ethernet alarm suppression, which greatly reduces the resources needed by the system to realize Ethernet alarm suppression and improves the speed of Ethernet alarm suppression processing. Degree.
After the implementation of the CFD module, it provides fast and reliable network connectivity monitoring to the enterprise and telecommunication networks, complements the lack of Ethernet in the OAM mechanism, thus providing a guarantee for the application of Ethernet in the telecommunication level network.
