【摘要】 中国农业大学校外场站分布在全国各地,急需构建互联互通的校园网络,但传统的专线方案构建成本高、新增节点部署周期长、运维复杂、广域网线路资源利用率低,而VPN方案因自身性能和功能具有局限性,无法直接从根源上实现跨地域校区及校外场站之间稳定高效的互访。为解决此问题,基于SD-WAN+流量识别调度技术设计具有通用性、部署方便、成本低、通信线路稳定、高安全的新型跨地域"校园一张网"。该系统解决了校外场站底层承载线路IP经常变化的问题,提供了价格低廉的双向网络互联互通解决方案,便于全校各管理业务系统的深度实质性融合及协同办公,从而提高管理和运维效率以及集约化经费使用。实际应用结果表明,在上庄通过SDWAN隧道访问校本部资源的时延均约为14.5 ms,效果良好。更多还原

【Abstract】 A new cross-regional campus network based on SD-WAN+traffic scheduling is designed and implemented to meet the unified campus network requirement in China Agricultural University.It provides a convenient deployment and cheap network access solutions.Results show that the system has characteristics of good expansibility,application-aware routing,high security,monitoring,and can be easily applied to branch campus which hasn’t wire network connection to main campus,to meet the needs of deep and substantive integration and collaborative office among main campus and serial branch campuses.Now this system has been put into use in Shangzhuang experimental base,through which that the delay of accessing the main campus resources from Shangzhuang is about 14.5 ms on average,with good effect.更多还原
