Healthcare成本谈判者可提高Aruba EdgeConnect SD-WAN的远程用户的应用访问和经验质量

为了向医疗保健提供者和保险公司提供节省成本的解决方案，这家公司在美国的员工必须在中央数据中心访问其关键的VoIP系统和商业和数据分析应用程序。然而，在广域网（WAN）上的MPLS运输撤销导致不可预测的性能，这对于确保业务生产率和高质量的客户服务来说是不可接受的。

The company's senior director of telecom and data center management, explains, "We had two MPLS providers for each office, but brownouts were common and could be very disruptive to the business. Combined with limited WAN visibility and the high cost of MPLS, we decided to invest in SD-WAN."

Gaining More Network Control

MPLS撤消不触发自动故障转移，因此IT团队必须依赖提供商解决任何问题 - 并且响应通常很慢。即使在电路中断的情况下，如果来自一个MPLS提供商的流量将自动失败到另一个MPLS电路或备份专用Internet访问（DIA）链接，则故障转移过程可能需要15到45秒，以此时间扰乱服务。

SD-WAN.was identified as a way to gain more control over network service reliability and quality. After evaluating Silver Peak, acquired by Aruba, a Hewlett Packard Enterprise company, along with Cisco and CloudGenix, the company selected the阿鲁巴EdgeConnect SD-WAN edge platformwith optional阿鲁巴促进WAN optimization。银色峰（现在Aruba）的事实始终如一地作为Gartner魔法象限的领导者是决定的一个重要因素。

The senior director notes, "We also favored EdgeConnect because it provides voice replication across multiple links, which is critical to prevent dropped calls for our contact centers and negotiating teams."

SD-WAN Resolves Brownout Issues

该公司将EdgeConnect平台部署在其全国范围内的每个国家办事处，以及其生产和灾难恢复数据中心。商务办公室配备双冗余EDGeConnect设备，配置为高可用性，并终止了一个MPLS电路，一个导向器和宽带连接。

高级总监，EdgeConnect通过同时提供给我们的所有三个链接，在所有三个链路上都会自动加载到任何三个链接的流量，“高级总监说。“MPLS撤消不再是一个问题，并且通过一个链接到另一个链接的子第二部分故障转移，故障转移是不可化的。员工可以做他们的工作，客户可以访问他们的门户，由于网络问题而没有中断。”

Unifies routing and simplifies security

With routing interoperability and a zone-based stateful firewall unified on EdgeConnect, the company retired its MPLS routers and legacy firewalls at all but two sites, consolidating from four devices to just two EdgeConnect appliances at each location.

The senior director says, "We no longer need support on those separate devices, which is a cost saving, and we reduced the number of potential points of failure."

为了保护SD-WAN，仅允许从一个EDGeConnect设备到另一个用于数据中心访问和Office通信的流量。一个例外是本地互联网突破，通过EdgeConnect上的基于区域的有状态防火墙，使办公室能够直接访问基于云的解决方案，例如缩放和WebEx。

“Being able to configure local breakout based on application type is an additional benefit of the Aruba EdgeConnect SD-WAN edge platform," the senior director points out.

Centralized visibility and control

Another advantage Aruba brings, especially compared to other SD-WAN vendors the company considered, is the阿鲁巴Orchestratormanagement console. Orchestrator provides the IT team with centralized management for the entire nationwide SD-WAN.

使用Orchestrator，该团队可以轻松应用于不同类别的应用程序的业务意图叠加层。例如，VoIP被分类为实时，而基于Web的应用程序被分类为关键，保证每个应用程序类基于业务优先级所需的网络资源。

Orchestrator还提高了网络可见性，简化了更新和故障排除。“之前，我们在湾发生了什么数据，”高级总监召回。“现在，Orchestrator使我们能够在每个叠加层上看到流量，因为它呈现给EDGeConnect设备。信息都在一个地方而不是多个控制台，这使得我的团队更容易获得所需的详细网络报告和分析。“

提高生产力和体验质量

确保始终如一的高应用性能是公司业务生产力的核心。通过在所有数据中心和联系中心应用程序跨越促进WAN优化，员工对应用程序性能的显着提高，尤其是远程办公室的剧烈提高。

“促进has been a big help for our work-at-home locations, some of which are very remote," the senior director says.

He also points out that employees who use Citrix to connect back to the data centers saw the greatest improvement. "We've cut response time in half with Citrix—in many cases from four seconds to two seconds or less."

The senior director concludes, "Providing reliable access to our data center applications is key to the business. The Aruba SD-WAN meets that important need, and delivers a high quality of experience to both employees and customers."
