摘要
以四川速宝网络科技有限公司上海璞速网络科技分公司的SD-WAN产品传输路径优化技术研究项目为基础,针对SD-WAN网络中使用互联网线路取代MPLS专线后网络质量下降的问题,提出了在SD-WAN多WAN线路的基础上使用双发策略的技术方案。双发策略包括持续双发策略和动态双发策略。对于动态双发策略,提出了一种以网络质量参数时延、抖动以及丢包等参数为基础的线路质量评分系统,并在评分基础上计算双发补偿率的公式。通过测试验证和客户现网实际应用部署,提出网络传输路径优化技术,即使在互联网线路出现质量下降也能保证业务的正常使用,节省了用户网络成本。
Based on the research project of SD-WAN product transmission path optimization technology of Shanghai Pusu Network Technology Branch of Sichuan Suibao Network Technology Co.,Ltd.,this paper proposes a technical scheme of using double-engine strategy on the basis of SD-WAN multi-WAN line,aiming at the problem of network quality decline after using Internet line to replace MPLS special line in SD-WAN network.Doubleshot strategy includes continuous double-shot strategy and dynamic double-shot strategy.For dynamic doubleshoot strategy,a line quality scoring system based on network quality parameters such as delay,jitter and packet loss is proposed,and the formula of double-shoot compensation rate is calculated based on the scoring.Through the test verification and the actual application deployment of the customer’s current network,the network transmission path optimization technology is put forward,which can ensure the normal use of the service even if the quality of the Internet line declines,and saves the user’s network cost.
