Granville ISSN: 2070-1721 Federal University of Rio Grande do Sul A. Clemm Huawei A. Gonzalez Prieto VMware February 2018 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. This document is a product of the IRTF Network Management Research Group (NMRG).

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 aShow full document text
