Network Analytics and Automation Abound: Enhance the Operator Experience with Aruba CX

今天的网络的重要性不能被夸大。想一想我们在这个数字时代中大多认为是理所当然的经验。在线登机，流媒体媒体，银行业务 - 我们的生活比以往任何时候都更加数字化，但是如果没有可靠的，始终在线的网络连接的情况下，这种经历将是不可能的。

When networks underperform or go down, there is a huge impact on revenue, productivity and customer satisfaction. The reported cost of downtime varies, depending on which report you read, but most put it in the range of $300,000 to $500,000 per hour. That’s some serious cash.

Unfortunately for IT operators, resolving network-impacting problems in a timely manner is more challenging than ever before. That’s because today’s networks are overwhelmingly complex. They’re built on disparate architectures, leverage multiple modes of transport, and connect headquarters, branch offices and mobile users to apps hosted in data centers and the public cloud. The source of a performance issue can be anywhere.

其次，网络运营商的任务是不间断的更新，以支持不断发展的业务需求。但是，通过设备手动实施更改是耗时且容易出错的，只会增加问题或中断的风险。

所有这些都引出了一个问题 - 如果网络对于将企业推向未来至关重要，为什么运营商必须依靠昨天的工具和流程来管理它们？

这是我们经常从客户那里听到的问题，这不是我们轻轻地接受的。您可能已经听说过我们最近介绍给的令人兴奋的创新Aruba CX切换投资组合改变当今数字世界的网络。好吧，在这个博客中，我想强调我们所做的自动化和分析增强功能，这将改变管理这些关键网络的运营商的体验。

使用Aruba网络分析引擎分布式分析

When we first launched the Aruba CX Switching Portfolio in June 2017, included was the阿鲁巴网络分析引擎(NAE), an on-box application powered by AOS-CX, our cloud-native operating system. NAE interrogates and analyzes any event that could impact network health. Operators benefit from rich analytics embedded in every CX switch, so they have the insights to readily detect and troubleshoot issues.

现在，我们已经将CX投资组合扩展到了校园访问，运营商可以从整个网络的分布式分析中受益，以更快地检测和解决。这与其他网络监视和故障排除方法相比如何？

Well, network operators used to rely on polling or SNMP traps to try and capture performance problems, but this is often like finding the proverbial needle in the haystack. Streaming telemetry to a central collector is another common approach, but this often results in raw, unfiltered datasets that aren’t readily actionable for troubleshooting, and it also places added strain on the network.

A number of third-party monitoring tools are also available; however, most merely sample data because they can’t provide the scale to collect everything that may be of interest. Without this level of resolution, network operators can’t readily investigate and resolve short-lived or intermittent problems.

Aruba Network Analytics引擎通过智能预处理数据来克服这些权衡，这些数据将原始遥测变成可行的见解。通过时间序列数据图和其他功能强大的可视化，该数据以直观的，基于Web的UI表示，例如您在下面看到的仪表板中。

易于动力的代理人建立要监视的数据，指定哪些条件构成不规则行为，然后在满足该病情时自动化诊断动作。操作员可以在UI中轻松设置和修改这些参数。

The latest release of AOS-CX delivers additional NAE agents for monitoring application, network and device performance. For example, the application health agent can identify whether an application issue is due to an anomaly with the connection setup, the application itself, or the link to the application server. The agent uses two techniques—monitoring the TCP handshake for successful connections or monitoring a customer-configured IP SLA session for things like round-trip time or jitter.

When an anomaly is detected, the NAE agent immediately alerts the operator to the problem and pinpoints where in the network it’s occurring. It can eventrigger a ticket in ServiceNow或其他事件管理工具，并传递相关的诊断细节，例如IP SLA会话统计信息。

With NAE, there is no more manual polling for issues or sifting through multiple data sources when an event of interest occurs. Instead, NAE proactively detects issues and automatically correlates the associated data to probable root cause—all presented to operators within their existing tools and workflows.

Enhanced Network Automation with Aruba NetEdit

我们发布了Netedit去年，对于经常在极度紧密的窗户中完成不间断的动作，添加和更改的网络运营商的寿命极大地简化了生活。NetEdit自动化了网络中所有相关设备的配置更改的推出，同时立即验证了此类更改符合网络策略。

将此与使用CLI或重写脚本的开销进行更改设备的乏味，以在多个设备上推出更新的配置。然后，手动执行现场检查以确保这些更改是有效且一致的。

Netediteliminates this resource drain. And, with the latest release of NetEdit, we’re bringing even more simplicity to the network operator experience.

在增强功能中，如上图所示，网络拓扑视图为整个网络健康提供了实时快照，每个网络设备都具有红色/黄色/绿色状态。这种拓扑本质上是动态的，可以根据操作员选择的网络层的哪些层来提供量身定制的视图 - 设备，应用程序，网络服务，例如路由和细分等。

健康信息由NAE的分析供电，NAE现在已集成到Netedit中。在调查网络健康并调查潜在或现有问题时，这进一步减轻了IT运营商的负担。

We’ve also introduced enhanced, GUI-driven menus that even further simplify the process of deploying common config changes. As depicted in the screen above, by typing in a couple of parameters and making a couple of clicks. operators can set up dynamic segmentation tunnels between a switch and a policy enforcement firewall to isolate new IoT devices from other parts of the network.
