Cisco Application Delivery Networks provide the acceleration, security, and availability customers need to improve application service across the extended enterprise
BARCELONA, Spain (PRWEB) January 22, 2008
"Customers deploy application switches such as the new Cisco ACE appliance to improve the performance of mission-critical applications in the data center, and Cisco WAAS WAN Optimization solutions to improve application performance over the wide-area network," said Gordon Daugherty, vice president of corporate development for NetQoS. "The NetQoS Performance Center provides the key metrics for building a comprehensive picture of Cisco Application Delivery Network improvements, including response times, which are critical to understanding how the application and server are performing for the end user, as well as Cisco IOS(R) NetFlow traffic analysis and device performance monitoring."
For example, to quantify the performance improvements of a Cisco ACE application switch, the NetQoS Performance Center baselines normal performance before deployment and continuously calculates network, server and application response times after deployment. Traffic analysis via NetFlow helps ensure that the same type and volume of traffic is still hitting the servers. In addition, device performance monitoring measures improvements in SNMP statistics such as CPU, memory, and disk utilization.
"Cisco Application Delivery Networks provide the acceleration, security, and availability customers need to improve application service across the extended enterprise," said George Kurian, vice president and general manager of Cisco's Application Delivery Business Unit. "NetQoS specializes in providing performance analytics across an enterprise infrastructure. By extending support to include both Cisco WAAS and ACE, customers now have a single data-center-to-WAN solution to understand and prove the value they are receiving from our products, as well as help quickly troubleshoot any issues that may be impacting application delivery."
When deviations from normal performance occur in a Cisco Application Delivery Network, the NetQoS Performance Center helps isolate the source of the problem to the network, server or application and launches automatic investigations into the issue. For instance, in one customer scenario the NetQoS Performance Center alerted the network team to a slowdown in server response time for a load balanced server. The NetQoS Performance Center showed that response times and CPU utilization were abnormally high, and that the traffic coming from the edge to that particular server in the data center was a new worm. The network team configured the dpi functionality on the ACE module to block that traffic and resolved the problem.
"The advanced functionality of today's application switches can provide significant improvements in application performance, but relying solely on qualitative or SNMP-based metrics is not enough to demonstrate improved application delivery to the end user," said Zeus Kerravala, senior vice president, Yankee Group. "The ability to measure response times is key, as is an understanding of the composition of traffic on the network. In fact, having before and after visibility into these performance metrics is essential to understanding which applications need improvement and determining if your load balancing solution is facilitating those improvements."
NetQoS and Cisco will be working with customers to help them understand how to measure Cisco Application Delivery Network performance improvements.

About the NetQoS Performance Center
The NetQoS Performance Center product suite provides global visibility, via a single Web-based management console, into the key metrics necessary to quantify network performance across an organization: end-to-end performance, traffic analysis via Cisco(R) IOS(R) NetFlow and IPFIX, device performance, long-term packet capture and analysis, and VoIP performance. The NetQoS Performance Center integrates the metrics in customized views to help organizations be more effective in capacity planning, troubleshooting, and service level management. With its role-specific views for different groups in an IT organization, such as network engineering, operations, and IP telephony management, the NetQoS Performance Center enables staff at all levels to:
-- Measure end-user application response times
-- Provide consistent application service delivery
-- Track VoIP quality metrics to ensure VoIP quality of experience
-- Understand how infrastructure changes affect network and application performance
-- Isolate performance problems to the application, server, or network
-- Identify the applications and users consuming bandwidth, and when
-- Avoid unnecessary WAN costs
-- Manage the convergence of voice, video and data
-- Identify virus or denial of service attacks
