The software-defined networking wide-area networking (SD-WAN) wave has surprised many with its depth and penetration into enterprise and service provider networking circles. I predict it will go even deeper. This is because of the ongoing integration ofSD-WAN使用软件定义的分支（SD分支）。
云服务，服务提供商网络和企业网络的持续趋势都朝着相同的方向前进 - 推动了更多的灵活网络，这些网络可以管理和确保云和按需云和规模。SD-WAN和SD-Branch的创新将继续将此功能推向企业网络。
At the same time, the physical underlay technologies of wireline and wireless technologies will need to be further levered using software-defined technology. The arrival of Wi-Fi 6, 5G, and private wireless technologies such as citizen’s broadband radio service (CBRS) present unique opportunities to augment enterprise and end-user network access. As Wi-Fi taught us, why should you care where you are and what network you are on? Users should be able to find seamless, secure bandwidth on demand – from wherever they are.
SD-WANand SD-Branch are poised to deliver all of this. Call it what you want – SD-WAN, SD-branch, or SD-Edge – it will give enterprise network managers and end users a new range of flexible, diverse services.
Silver Peak的创始人兼Aruba WAN业务高级副总裁David Hughes说：“我们认为优势是数字化转型的核心。”“从以数据为中心的基于MPLS的WAN转变为完全利用Internet的云首次WAN，将使企业能够桥接到他们明天想去的地方。”
网络变得多云
让我们不要在行话中陷入困境。最终，无论您是SD-WAN还是SD分支机构，都没关系。图片的重要部分是，这两组技术 - SD-WAN专注于向外的分支，而SD分支集中在企业分支和内向上 - 两者都受到软件定义网络的同样重要概念的支持（SDN（SDN））。也就是说，您不希望通过物理设备定义网络，而希望通过软件驱动的管理模型可以使用基于云的服务进行集中控制。
这是很重要的,因为SDN技术可以我们ed to quickly manage or adopt any combination of underlying transport technologies – such as MPLS, DIA, broadband Wi-Fi, 5G, or even fiber, for example. The SDN nature means that these technologies can be quickly assimilated and cloudified to deliver value to the end users.
软件定义的无线和有线功能的收敛性已成为领先的企业网络平台的标准功能，例如来自Aruba的EdgeConnect和SD-Branch平台。企业希望整合LAN，WAN，5G和WI-FI的功能，包括轮毂和辐条，部分网格，动态全网格或直接企业和云连接。他们想使用当地的Internet突破之类的功能来优化其网络并为用户提供最高质量的体验。同时，他们希望使用新技术，例如人工智能（AI）和机器学习来自动化这些网络的管理和安全性。
For a while, SD-WAN (branch out) and SD-Branch (branch in) have been evolving similarly in parallel markets – adopting SDN capabilities, cloud security services and AI-driven centralized management. It’s time for these parallel developments to merge, which is why you have seen leaders such as Aruba make inroads toward integration, acquiring leaders like Silver Peak and quickly integrating advanced technologies to better address the evolving requirements of geographically distributed enterprises.
这两个系统（Enterprise Branch和SD-WAN）将合并和集成，所有这些都会对用户受益。没有理由为什么单个SDN平台不应控制WAN，分支和LAN的网络和安全功能。LTE，Wi-Fi和5G等无线功能将成为标准分支连接选项以及SD-WAN托管服务的一部分。
这将使零售商或工业用户等最终用户可以根据其角色而不是其位置来区分基于云网络的特定用户，设备和应用程序。
不容忽视的另一个发展是自动编排领先的云传递安全服务。例如，阿鲁巴（Aruba）在统一的本地WAN EDGE安全功能和最佳云裁定的安全服务之间取得了平衡，所有这些服务都通过其Aruba Orchestrator Management Console进行了无缝管理，它可以说，它可以应用并执行一致的安全策略。成千上万的远程位置”，无论这些位置是链接到云还是与传统数据中心链接的。
End Users Have Their Say
Futuriom知道企业IT组织希望在边缘进一步整合SDN，因为在我们的常规采访和调查中，他们告诉我们这就是他们想要的。
There is strong demand to integrate SD-WAN with SD-Branch and wireless. In our newly released 2021 SD-WAN Managed Services Survey, nearly 90 percent of the 120 enterprise end users surveyed said that SD-Branch features for wireless and wired management are important in SD-WAN managed services. Just three percent responded “No,” and about eight percent responded with “Not Sure."
正如我们的调查显示的那样，网络和IT经理正在寻求更大的灵活性，以将分支机构与软件驱动的模型联系起来，从而使他们能够快速将新的分支机构带到网上。
An example could be a global Fortune 500 company managing hundreds of branch offices for a bank, or a regional chain of retail stores looking for easy-to-manage WAN connectivity. Network and IT managers have shown a strong affinity for improving the ease-of-use and management of branch offices.
随着SD-WAN玩家争先恐后地将自己定位在许多竞争对手的热门市场中，Aruba的位置很好，因为它在无线网络及其扩展的企业网络和安全产品组合中的投资组合。
