【摘要】：中國移動已大規(guī)模現(xiàn)網(wǎng)部署應(yīng)用PTN設(shè)備，目前已開始統(tǒng)一承載2G/3G業(yè)務(wù)，并且在部分地區(qū)還承載了大客戶業(yè)務(wù)和LTE試驗網(wǎng)業(yè)務(wù)，因為PTN帶寬較大（通常匯聚層為10GE以上），所以對其網(wǎng)絡(luò)的可靠性提出了很高的要求。對PTN斷路保護機制的研究是PTN技術(shù)研究里不可或缺的一項工作。目前上海移動現(xiàn)網(wǎng)PTN網(wǎng)絡(luò)主要采用線性標(biāo)簽交換通道LSP（Label Switched Path）線性保護。但是由于網(wǎng)絡(luò)現(xiàn)在越來越大，當(dāng)現(xiàn)網(wǎng)中存在多點故障等復(fù)雜情況時，同一PTN環(huán)網(wǎng)多處中斷很可能導(dǎo)致主備用LSP保護均中斷，從而導(dǎo)致業(yè)務(wù)中斷，存在一定的安全隱患。 本文通過分析PTN的主要保護方式：線性保護以及環(huán)網(wǎng)保護方式，針對上海移動現(xiàn)有PTN網(wǎng)絡(luò)特點，研究出一種新的PTN的斷路保護機制。此機制就是將環(huán)網(wǎng)保護和線性保護聯(lián)合起來一起應(yīng)用，在原有上海移動PTN網(wǎng)絡(luò)LSP保護的基礎(chǔ)上，在其匯聚層加上環(huán)網(wǎng)保護，從而達到抗多點故障的目的。通過搭建這樣一個新的斷路機制模型，用儀表模擬用戶，在實際的設(shè)備上經(jīng)行斷路實驗，通過驗證多點故障、網(wǎng)元故障等現(xiàn)網(wǎng)常見的問題，來查看模型的效果和可行性。結(jié)果得出環(huán)網(wǎng)保護和線性保護相結(jié)合的方式可以很好地達到PTN網(wǎng)絡(luò)抗多點故障的目的，這樣一種新的保護機制可以增加PTN網(wǎng)絡(luò)的安全性以及可靠性。 本論文將環(huán)網(wǎng)保護機制應(yīng)用到大型的運營分組網(wǎng)絡(luò)中，，在國內(nèi)和國際上都是率先的嘗試。因此這一成果對國際、國內(nèi)企業(yè)標(biāo)準(zhǔn)的制定，以及專利和知識產(chǎn)權(quán)保護方面，都有積極的推動作用。
[Abstract]:China Mobile has deployed PTN equipment on a large scale and has begun to carry 2G/3G services uniformly, and has also carried major customer services and LTE test network services in some areas. Because the bandwidth of PTN is large (usually the convergent layer is more than 10GE), the reliability of PTN network is very high. The research on the mechanism of PTN open circuit protection is an indispensable work in the research of PTN technology. At present, PTN network of Shanghai Mobile mainly uses linear label switching channel LSP (Label Switched Path) linear protection. However, as the network is getting larger and larger now, when there are complex situations such as multi-point faults in the present network, the multiple interruptions in the same PTN ring network will probably lead to the interruption of the main and standby LSP protection, which will lead to the interruption of the service and the existence of certain security risks. This paper analyzes the main protection methods of PTN: linear protection and ring network protection. According to the characteristics of the existing PTN network of Shanghai Mobile, a new open circuit protection mechanism of PTN is developed. This mechanism is to combine the ring network protection and linear protection together. On the basis of the LSP protection of the original Shanghai Mobile PTN network, the ring network protection is added in its convergent layer, so as to achieve the purpose of resisting the multi-point fault. By setting up such a new open circuit mechanism model, simulating the user with the instrument, running the experiment on the actual equipment, checking the common problems of the network, such as multi-point fault, network element fault and so on, to see the effect and feasibility of the model. The results show that the combination of ring network protection and linear protection can achieve the purpose of resisting multipoint fault in PTN network. This new protection mechanism can increase the security and reliability of PTN network. In this paper, the ring network protection mechanism is applied to the large operation packet network, and it is the first attempt both at home and abroad. Therefore, this achievement has a positive impact on the establishment of international and domestic enterprise standards, as well as patent and intellectual property protection.
