[edit] Cisco IOS IP Service Level Agreements (IP SLAs)

Introduction

Cisco IOS IP Service Level Agreements (SLAs) is a feature of Cisco IOS Software that enables customers to assure new business-critical IP applications, as well as IP services that utilize data, voice, and video, in an IP network. Cisco has augmented traditional service level monitoring and advanced the IP infrastructure to become IP application-aware by measuring both end-to-end and at the IP layer.

With Cisco IOS IP SLAs, users can verify service guarantees, increase network reliability by validating network performance, proactively identify network issues, and simplify the deployment of new IP services. Cisco IOS IP SLAs use active monitoring to generate per-packet measurement traffic to enable the measurement of network performance and health.

[edit] What IP SLAs Does

With IP SLAs, routers and/or switches perform periodic measurements. These include:

The exact number and type of available measurements depends on the IOS version. IP SLAs enables building truly distributed performance collection systems. IP SLAs is very widely used in networks to generate time-based network and services performance data. It is typically used together with SNMP and Netflow which generate volume-based data. IP SLAs is often used to generate data which is need by Service Level Agreements.
