医疗保健成本谈判者改善了Aruba EdgeConnect SD-WAN的远程用户的应用程序访问和经验质量

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，该公司的员工必须在中央数据中心访问其关键VOIP系统以及业务和数据分析应用程序。但是，MPLS在广阔的网络（WAN）上运输BrownOut引起了不可预测的性能，这对于确保业务生产力和高质量的客户服务是不可接受的。

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 brownouts don't trigger automatic failover, so the IT team had to rely on the provider to resolve any issues—and the response was often slow. Even in the event of a circuit outage, where traffic from one MPLS provider would automatically fail over to another MPLS circuit or a backup dedicated internet access (DIA) link, the failover process could take 15 to 45 seconds, disrupting services for that time.

SD-WANwas 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 optionalAruba Boost Wan优化。银峰（现为阿鲁巴）在Gartner Magic象限中始终如一地排名是该决定的重要因素。

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解决了布朗特问题

该公司在其全国办事处及其生产和灾难恢复数据中心部署了EdgeConnect平台。业务办公室配备了双冗余EdgeConnect设备，配置为高可用性，并用一个MPLS电路，一个DIA链接和宽带连接终止。

高级总监说：“借助我们同时使用的所有三个链接，EdgeConnect自动加载了所有三个链接的流量，这是不可能的。”“ MPLS BrownOt不再是一个问题，并且由于从一个链接到另一个链接的次秒故障转移，故障转移却不牢固。员工可以从事工作，客户可以在网络上访问他们的门户网站，而不会因网络问题而受到干扰。”

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，仅允许流量从一个EDGECONNECT设备到另一个用于数据中心访问和办公室间通信。一个例外是本地Internet突破，该突破通过EdgeConnect上的基于区域的状态防火墙确保，使办公室能够直接访问基于云的解决方案，例如Zoom和Webex。

“能够配置本地基于一个突破pplication 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.

使用编排者，团队可以轻松地将业务意图叠加应用于不同类别的应用程序。例如，VOIP被归类为实时，而基于Web的应用程序被归类为关键，确保每个应用程序类基于业务优先级所需的网络资源。

编排还提高了网络可见性，简化更新和故障排除。高级总监回忆说：“以前，我们几乎没有关于WAN发生的事情的数据。”“现在，编目使我们能够看到每个覆盖层上的流量，因为它呈现给EdgeConnect设备。信息全部位于一个位置而不是多个控制台，这使我的团队更容易获得所需的详细网络报告和分析。“

提高生产力和经验质量

确保始终如一的高应用绩效对公司的业务生产力至关重要。通过在所有数据中心和联系中心应用程序中应用Boost WAN优化，员工已经看到了应用程序绩效的改善，尤其是在偏远办公室中的绩效。

“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."

高级总监总结说：“提供对我们数据中心应用程序的可靠访问是业务的关键。阿鲁巴SD-WAN满足了这一重要需求，并为员工和客户提供了高质量的经验。”
