Autonomic Networking Use Case for Distributed Detection of
Service Level Agreement (SLA) Violations
Abstract
This document describes an experimental use case that employs
autonomic networking for the monitoring of Service Level Agreements
(SLAs). The use case is for detecting violations of SLAs in a
distributed fashion. It strives to optimize and dynamically adapt
the autonomic deployment of active measurement probes in a way that
maximizes the likelihood of detecting service-level violations with a
given resource budget to perform active measurements. This
optimization and adaptation should be done without any outside
guidance or intervention.

1. Introduction
The Internet has been growing dramatically in terms of size,
capacity, and accessibility in recent years. Communication
requirements of distributed services and applications running on top
of the Internet have become increasingly demanding. Some examples
are real-time interactive video or financial trading. Providing such
services involves stringent requirements in terms of acceptable
latency, loss, and jitter.
Performance requirements lead to the articulation of Service Level
Objectives (SLOs) that must be met. Those SLOs are part of Service
Level Agreements (SLAs) that define a contract between the provider
and the consumer of a service. SLOs, in effect, constitute a
