挑战

网络应用程序,例如电子病历 (EMR) 或电子健康记录 (EHR),对于 Cook Children's 为其患者和医生提供出色的服务至关重要。随着其网络变得越来越复杂,数据来自各种无线医疗设备和可穿戴设备,以及远程托管应用程序,问题浮出水面。该组织的网络经理发现了一系列问题,包括用户体验缓慢、网络监控挑战以及无法主动识别应用程序性能问题。

在仔细搜索替代方案后,Ixia 的网络工具优化器 (NTO) 在网络接入点之间实施,以增强 APM 平台的网络流量可见性。选择 OPNET AppResponse Xpert 来满足 APM 要求。

• APM——OPNET APM Xpert 套件支持 24x7 应用程序事务监控、数据包存储和网络分析,同时为依赖映射、SNMP 报告、数据库监控和部署前应用程序测试提供集成的软件插件。

• 聚合和过滤——实施 Ixia NTO 以聚合来自多个 10G SPAN 的流量,并在过滤掉重复数据包后将其定向到 OPNET 设备。 “NTO 使得从我们数据中心的任何地方向我们的 OPNET AppResponse Xpert 提供所需的所有流量变得非常简单和高效,”Cook Children's Health 的网络经理 Ross Jones 说。 “删除不需要的重复数据包是一个巨大的好处。”

运营影响
  • [Efficiency Improvement - Issue Response]
    Faster troubleshooting – problem isolation reduced from days to hours • Proactively seeing and resolving issues before they become problems. • Complete network traffic visibility for application performance analysis. • Improving efficiency of APM system by removing duplicate packets. • No interference with other department’s network probes thanks to SPAN/Tap sharing.
  • [Efficiency Improvement - Maintenance]
    Before the APM deployment, the networking team would often not be aware of slow response times on the remotely hosted Electronic Medical Records (EMR) application until a physician would call in to complain.Once the problem was identified, it took time to sort out if the root cause of the issue was the application or the network. This issue was resolved by baselining and continuously monitoring WAN network latency. Thresholds were set using OPNET’s alert functionality so that the networking team can be aware of and correct potential issues before users complain. When problems do occur, the mean time to repair (MTTR) is reduced by focused root cause analysis.
