在数字加速时代，不监视最终用户数字体验的成本是巨大的！从增加的帮助台呼叫和频繁的卡车滚动开始到更高的运营费用，降低员工效率以及激怒的客户，它最终可能会侵蚀组织的竞争差异。随着企业采用数字优先的方法，IT团队将过渡到业务关键职能，业务重点和它聚集在为最终用户提供出色的数字体验上。这不仅释放了新的收入机会，而且还会显着影响客户保留率。
缺乏对网络和应用程序性能以及缺乏具体方法来验证最终用户数字体验的可见性，这会导致IT团队平均花费70％的时间（来源：Gartner - 2019年6月）解决网络问题，几乎没有带宽，几乎没有带宽他们补充业务优先事项并支持新的收入轨迹。最终用户希望该网络无缝地工作，并希望尽快解决中断。IT团队并不总是在现场出现，以快速解决问题并处理诸如“ CRM不工作”，“协作工具不加载”，“语音通话”等轶事投诉非常困难。
最大的问题是——如何确保最终用户are getting a seamless digital experience on the network? One way of achieving this is by deploying human testers who can monitor the end-user experience on the network, on each corner of the facility, on each floor, in each city, in each country, and across the whole world! Well, seems like a highly cumbersome and costly task!
We at Aruba have been trying to address this burning challenge along with a few other questions such as - How do IT teams efficiently track network health while keeping a check on end-user experience? How do they ensure that different apps are reachable on the network? How do they see if all the managed sites across the world are available, and when something fails how do they get the precise insights to troubleshoot and fix the issues rapidly!
In this five-blog series of ‘Inside out and outside in’ of a network, we explore how the combined solution of Aruba Central and Aruba UXI provides a powerful, one-stop solution for IT teams to understand network and application performance from a network and user’s perspective simultaneously! (Please read the first two blogs if you haven’t already:博客1，，，，博客2.)
In this third blog of the series, we will discuss how Aruba Central and Aruba UXI serve as a simple and highly efficient solution to address all the issues discussed above. Aruba Central provides a single point of control to manage network operations and get visibility into network performance from the network’s perspective. On the other hand, Aruba UXI onboards the network like an end-user and tests applications performance on the network from an end user’s perspective.
In this blog, we will discuss a scenario where IT teams were able to deliver a great user experience with the combined power of Aruba Central and Aruba UXI.
Scenario –A large K12 with dorms in the states recently upgraded its network to support 1:1 digital learning, eLearning, and remote access to classes. They upgraded their network infrastructure to ensure consistent connectivity to critical EdTech applications and school servers. The college couldn’t afford connectivity dropouts as it would affect the school’s grading, and staff’s efficiency and students’ learning outcomes. Here are some steps they took to achieve this with efficacy and business- critical objectives in mind:
- K12决定使用Aruba Uxi和Aruba Central来监视和管理学校网络。
Figure 1: Aruba UXI testing critical network and applications performance parameters in a K12 environment - IT团队在UXI内利用内置的测试来测试Edtech应用程序，并配置了在学校服务器上托管的关键应用程序，以全天进行测试。
- Aruba Central仪表板为他们提供了整体网络绩效数据的整体视图，并具有精确的精确见解和问题影响摘要。
图2：Aruba Central提供了AI动力的见解和影响摘要（网络升级之前） - 网络升级后，IT团队注意到UXI仪表板上针对学校内部服务器和Edtech应用程序的警报，这意味着学生可能面临Wi-Fi的困难。
- 的确，IT Hersdesk很快就收到了一些有关学生无法从宿舍里访问在线测试和课程的投诉。
- The UXI sensors placed strategically in the dorm hallway picked up the issues and proactively drilled down to identify the error as "802.1X auth failed. On checking the automatic triage report, the IT team found that the error was occurring due to a very low timeout value set on RADIUS side.
- The IT team instantaneously leveraged Aruba Central to verify the issue and found ‘802.1X authentication failure’ to be the root cause, they also successfully verified that APs were working perfectly.
- Central中的AI Insight屏幕还指出了身份服务器的IP地址（在“服务器”瓷砖卡中），帮助IT admin快速隔离有问题的Auth Server
Figure 3: Aruba Central highlighting the problematic Auth server along with recommendations - IT团队从Aruba Central仪表板远程更改了半径侧的超时值。他们还注意到学校的其他分支机构也是如此。该团队迅速采取行动，为所有其他学校分支机构部署了类似的网络政策。
- 立即，Aruba UXI仪表板展示了一张绿色的笑脸，表示问题已解决，学生和员工的数字体验良好。
学校在严重破坏学生的考试或时间敏感的电子学习活动之前就解决了一个主要的网络问题，并在所有学校分支机构中主动解决了这一问题。
Aruba Uxi和Aruba Central的强大组合帮助IT团队远程解决，隔离和解决问题。它不仅有助于IT团队减少平均分辨率（MTTR）和平均纯真时间（MTTI），而且还大大降低了潜在升级的机会。
This is the potential of using the powerful combination of Aruba Central + Aruba UXI, it help businesses provide an inside out and outside in perspective into network performance.
