【摘要】：隨著企業(yè)分支、行業(yè)站點(diǎn)的增加,以及物聯(lián)網(wǎng)的迅猛發(fā)展,接入互聯(lián)網(wǎng)的需求日趨旺盛,使用傳統(tǒng)的接入線路已逐漸無法滿足客戶的需求,比如高帶寬。人們一直致力于尋求一種在現(xiàn)有條件下能夠有效解決帶寬瓶頸并提高網(wǎng)絡(luò)系統(tǒng)可靠性的辦法。鏈路聚合技術(shù)很好的解決了這一難題,因而在網(wǎng)絡(luò)設(shè)備上研究與實(shí)現(xiàn)鏈路聚合技術(shù)有非常重要的意義。本文基于華為技術(shù)有限公司的接入路由器(Access Router,AR)的一個解決方案,在對AR設(shè)備的軟硬件深入研究的基礎(chǔ)上,完成了鏈路聚合技術(shù)在AR上的實(shí)現(xiàn),并取名智能VPN,即SVPN。首先,本文對SVPN的需求展開了分析,明確了需求的目標(biāo)和價(jià)值;其次,對SVPN的功能設(shè)計(jì)、整體模塊設(shè)計(jì)以及子模塊設(shè)計(jì)做了詳細(xì)闡述;再次,設(shè)計(jì)完成了 SVPN的兩種工作模式:單機(jī)模式和聯(lián)機(jī)模式;兩種調(diào)度方式:基于鏈路優(yōu)先級的Priority調(diào)度和基于鏈路帶寬的Overflow調(diào)度,并設(shè)計(jì)了 SVPN的數(shù)據(jù)結(jié)構(gòu)以及具體功能的實(shí)現(xiàn)方法;最后,本地搭建環(huán)境,對系統(tǒng)的功能和性能進(jìn)行了充分測試,驗(yàn)證了系統(tǒng)的可靠性和穩(wěn)定性。
[Abstract]:With the increase of business branches, industry sites, and the rapid development of the Internet of things, the demand for Internet access has become increasingly strong, and the use of traditional access lines has gradually been unable to meet the needs of customers, such as high bandwidth. People have been trying to find a way to solve the bandwidth bottleneck and improve the reliability of the network system under the existing conditions. The link aggregation technology solves this problem very well, so it is very important to research and implement the link aggregation technology on the network equipment. Based on a solution of access router (Access Router,AR) of Huawei Technology Co., Ltd., based on the deep research of the hardware and software of AR equipment, this paper completes the implementation of link aggregation technology on AR, and it is named Intelligent VPN, (SVPN.). Firstly, this paper analyzes the requirements of SVPN, and clarifies the objectives and values of the requirements. Secondly, the function design, the overall module design and the sub-module design of SVPN are described in detail. Two working modes of SVPN are designed and completed: single machine mode and on-line mode, two scheduling modes: Priority scheduling based on link priority and Overflow scheduling based on link bandwidth. The data structure of SVPN and the realization method of the specific function are designed. Finally, the local environment is built, and the function and performance of the system are fully tested, which verifies the reliability and stability of the system.
