NetQoS Announces End-to-End Support for Cisco Application Delivery Networks

NetQoS has teamed with Cisco to help network engineers quantify the performance improvements derived from Cisco Application Delivery Networks deployed using Cisco Application Control Engine (ACE) modules and appliances, and Cisco Wide Area Application Services (WAAS) products. In July 2007, NetQoS and Cisco together announced a management interface for Cisco WAAS to provide accurate response time monitoring in a WAN-optimized environment. Now, NetQoS is announcing advanced analytics support for Cisco ACE modules and appliances via the NetQoS Performance Center.

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.

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.
