【摘要】：隨著互聯(lián)網(wǎng)技術(shù)的迅速發(fā)展，對(duì)路由器設(shè)備性能的要求也越來(lái)越高，系統(tǒng)由集中式轉(zhuǎn)變?yōu)榉植际匠蔀橐环N趨勢(shì)。在分布式路由器中，點(diǎn)對(duì)點(diǎn)協(xié)議(Point-to-Point Protocol, PPP)作為一種提供在點(diǎn)到點(diǎn)鏈路上承載網(wǎng)絡(luò)層數(shù)據(jù)包的鏈路層協(xié)議，主要被設(shè)計(jì)用來(lái)支持全雙工的同步鏈路和異步鏈路上進(jìn)行點(diǎn)到點(diǎn)之間的數(shù)據(jù)傳輸。當(dāng)數(shù)據(jù)業(yè)務(wù)量增大、服務(wù)質(zhì)量要求較高時(shí)，一條PPP鏈路所擁有的帶寬就不能滿足客戶的需求，就需要多條PPP鏈路(Multilink PPP, MP)來(lái)完成。 本文來(lái)源于H3C的PPP二期項(xiàng)目，在集中式PPP基本功能的基礎(chǔ)上，對(duì)分布式的PPP進(jìn)行了研究，并在路由器平臺(tái)上實(shí)現(xiàn)PPP的分布式功能。 首先，，本文介紹了PPP和MP的相關(guān)概念，描述了多條PPP的整個(gè)鏈路建立過(guò)程，并對(duì)所要協(xié)商的鏈路控制協(xié)議、認(rèn)證協(xié)議和網(wǎng)絡(luò)控制協(xié)議的具體協(xié)商流程進(jìn)行了詳細(xì)的分析。接著介紹了本項(xiàng)目的軟件開發(fā)平臺(tái)和PPP的分布式設(shè)計(jì)技術(shù)。 其次，論文對(duì)PPP模塊的分布式總體構(gòu)架進(jìn)行了設(shè)計(jì)。在此構(gòu)架中實(shí)現(xiàn)了分布式PPP的配置實(shí)時(shí)同步、配置信息恢復(fù)、PPP的運(yùn)行信息恢復(fù)以及MP的運(yùn)行信息恢復(fù)等重要功能。為了進(jìn)一步提高用戶的上線速率，論文對(duì)PPP分布式系統(tǒng)還進(jìn)行了優(yōu)化，優(yōu)化過(guò)程中采用的是多線程的處理機(jī)制。 最后對(duì)分布式PPP進(jìn)行了功能測(cè)試和性能測(cè)試。功能測(cè)試驗(yàn)證了分布式PPP功能的正確性。性能測(cè)試分為負(fù)載測(cè)試和壓力測(cè)試。負(fù)載測(cè)試主要對(duì)用戶上線速率進(jìn)行了測(cè)試，通過(guò)對(duì)比集中式系統(tǒng)、分布式系統(tǒng)和優(yōu)化后的PPP分布式系統(tǒng)的用戶上線速率，結(jié)果表明分布式系統(tǒng)的PPP協(xié)商效率比集中式系統(tǒng)的PPP協(xié)商效率高，優(yōu)化后PPP分布式系統(tǒng)的協(xié)商效率比優(yōu)化前分布式系統(tǒng)的PPP協(xié)商效率高。而壓力測(cè)試結(jié)果表明系統(tǒng)的性能穩(wěn)定、可靠，達(dá)到了設(shè)計(jì)的要求。
[Abstract]:With the rapid development of Internet technology, the requirements for the performance of router equipment are becoming more and more high, and the transformation from centralized to distributed is a trend. In distributed routers, the point to point protocol (Point-to-Point Protocol, PPP) is a link layer protocol that provides the network layer data packet on the point to point link. It is designed to support full duplex synchronous links and asynchronous links on point-to-point data transmission. When the data traffic increases and the quality of service is high, the bandwidth owned by a PPP link can not meet the needs of the customer, and multiple PPP links (Multilink PPP, MP) are needed to complete.
This article comes from the PPP two project of H3C. On the basis of the basic function of centralized PPP, the distributed PPP is studied, and the distributed function of PPP is realized on the router platform.
First, this paper introduces the related concepts of PPP and MP, describes the whole link establishment process of multiple PPP, and analyses the detailed negotiation process of the link control protocol, authentication protocol and network control protocol that are to be negotiated. Then, the software development platform of this project and the distributed design technology of PPP are introduced.
Secondly, the paper designs the distributed overall framework of the PPP module. In this framework, the distributed PPP configuration is synchronized, the configuration information recovery, the PPP operation information recovery and the MP running information recovery are important functions. In order to further improve the user's on-line speed, the paper also optimizes the PPP distributed system. The multithread processing mechanism is adopted in the optimization process.
Finally, the function test and performance test are carried out on the distributed PPP. The function test verifies the correctness of the distributed PPP function. The performance test is divided into load test and pressure test. The load test is mainly tested on the user's on-line rate, by comparing the centralized system, the distributed system and the optimized PPP distributed system. The result of line rate shows that the PPP negotiation efficiency of distributed system is higher than that of PPP in centralized system. The negotiation efficiency of PPP distributed system after optimization is higher than that of PPP before optimizing distributed system. The results of pressure test show that the performance of the system is stable and reliable, reaching the design requirements.
