Application Response Time
Ensuring Quality of Service and Application Delivery Effectiveness With Application Performance Management and Deep Packet Inspection (DPI)
Overview
As application traffic volume increases and corporate end users become increasingly dependent on IP-based applications to do their jobs, it’s imperative that network applications be closely monitored and managed from an end-user quality of experience, and SLA compliance perspective. This perspective is particularly crucial for today’s global, centrally managed networks where digital business communications occur more frequently via a wide-area network (vs. a LAN) and over greater distances. Increased application traffic and the potential for network latency and packet loss can lead to application performance degradation that could impact the user community, unless properly addressed.
To ensure application quality of service (QoS) and meet SLA requirements, service providers and enterprises need application response time monitoring, an application performance management capability that allows them to measure the elapsed time between a user or client request and the server’s response to that request. Such measurements are an effective way to understand which applications are suffering from slow response times and whether the applications that users count on are being delivered in accordance with quality of service (QoS) expectations. With this information, network managers/traffic engineers can assign or reassess priority class of service treatment for the most critical or sensitive applications and more easily determine which applications are candidates for WAN optimization and application acceleration.
InfoVista's 5View solution for application response time management empowers customers to monitor the performance of applications across the entire WAN infrastructure. Equipped with the 5View™ Applications appliance and 5View™ Service Data Manager, with its 5View™ Application Response Manager option, organizations can ensure that application quality of service (QoS) is meeting corporate business needs and SLA objectives, and can identify performance-related issues such as which applications are loading the network, whether critical applications are getting the proper priority class of service treatment and performing at the expected response levels, and which sites have the worst response times for a given application.
Key Features
InfoVista’s 5View™ Application appliance and 5View™ Service Data Manager, with its 5View™ Application Response Manager option, provide:
- Richly detailed application performance management capabilities that enable internal or outsourced IT operations to more quickly and easily troubleshoot and resolve application problems, monitor application quality for trending and capacity planning, ensure quality of service (QoS), and report on SLA compliance
- Support of packet capture and analysis and
deep packet inspection (DPI) capabilities, which enables network managers to view application transactions beyond the IP header so they can identify who is using the application, the traffic type or priority of the application, which client and server is being used, and the most critical metric for understanding end-user experience: application response time - Historical and real-time application performance information, which allows service providers and customers to establish network and application performance baselines they can then use to determine and reassess quality of service (QoS) requirements and configure specific application acceleration policies
- Predefined, out-of-the-box reports and KPIs covering a variety of application performance perspectives (by customer, service, region, and more)
- Preconfigured alarms for detection of abnormal behavior, such as slow application response time, high retransmissions, or server inactivity
- Compatibility and a common platform with InfoVista’s VistaInsight® for Networks network performance management solution, resulting in a consistent view of network- and application- based services and faster ROI and operational efficiency
