Service Assurance Agent

Platforms: Cisco 7200 series, Cisco 7500/RSP series, Cisco 12000 series

The Service Assurance (SA) Agent is both an enhancement to and a new name for the Response Time

Reporter (RTR) feature that was introduced in Cisco IOS Release 11.2. The feature allows you to

monitor network performance by measuring key service level agreement metrics such as response time,

network resources, availability, jitter, connect time, packet loss, and application performance.

The SA Agent feature was introduced in Cisco IOS Release 12.0(5)T, and is now available in Cisco

IOS Release 12.0(8)S.

The SA Agent provides new capabilities that enable you to monitor:

• Domain Name System (DNS) performance. Thresholds can be used to trigger additional collection

of time delay statistics.

• Internet Control Message Protocol (ICMP), User Datagram Protocol (UDP) echo response time,

and TCP connection setup time, with different ToS settings in the IP header.

• Network one-way delay variance (jitter) and packet loss.

• Web server response time.
