Autonomic Networking Integrated Model and Approach (ANIMA)

This chapter presents the work of the Autonomic Networking Integrated Model and Approach (ANIMA) working group of the Internet Engineering Task Force (IETF). It was formed to standardize protocols and procedures for an ANIMA autonomic network (AN) and first chartered to define the ANIMA secure autonomic network infrastructure (ANI). This chapter describes the technical history and goals leading to this working group. It then describes how the ANIMA approach provides an evolutionary approach to securing and automating networks and to provide a common infrastructure to evolve into future autonomic networks. Finally, this chapter compares this approach to adjacent standards technologies and discusses interesting next steps.

Using the RFC 7575 and Models at Runtime for Enabling Autonomic Networking in SDN

The programmable network architectures that emerged in the last decade have allowed new ways to enable Autonomic Networks. However, there are several open issues to address before making such a possibility into a feasible reality. For instance, defining network goals, translating them into network rules, and granting the correct functioning of the network control loop in a self-adaptive manner are examples of complex tasks required to enable an autonomic networking environment. Fortunately, architectures based on the concept of Models at Runtime (MART) provide ways to overcome such complexity. This paper proposes a MART-based framework – using the RFC 7575 as reference (i.e., definitions and design goals for autonomic networking) – to implement autonomic management into a programmable network. The evaluation shows the proposed framework is suitable for satisfying the functional and performance requirements of a simulated network.

A Model-Driven and Business Approach to Autonomic Network Management

As corporate networks continue to expand, the technologies that underpin these enterprises must be capable of meeting the operational goals of the operators that own and manage them. Automation has enabled the impressive scaling of networks from the days of Strowger. The challenge now is not only to keep pace with the continuing huge expansion of capacity but at the same time to manage a huge increase in complexity – driven by the range of customer solutions and technologies. Recent advances in automation, programmable network interfaces, and model-driven networking will provide the possibility of closed-loop, self-optimizing, and self-healing networks. Collectively these support the goals of a truly automated network, commonly understood as “autonomic networking” even though this is a prospect yet to be achieved. This paper outlines the progress made towards autonomic networking and the framework and procedures developed during the UK Next Generation Converged Digital Infrastructure (NG-CDI) project. It outlines the operator-driven requirements and capabilities that have been identified, and proposes an autonomic management framework, and summarizes current art and the challenges that remain.

Análise da Sinalização na Arquitetura Proposta no IETF ANIMA: o GRASP

O avanço da tecnologia e complexidade de redes de computadores cria a necessidade de novos mecanismos de gerenciamento para tais redes. A intervenção humana não será mais efetiva, sendo necessário automatizar determinados processos. As redes autonômicas se apresentam para atuar em redes complexas e tomar decisões sem necessitar de um administrador de rede e repassando a responsabilidade de resolver problemas para os nós da rede autonõmica. O Autonomic Networking Integrated Model and Approach ANIMA Working Group (WG) tem por objetivo propor uma arquitetura para redes autonômicas. Nessa arquitetura, a sinalização é realizada pelo GeneRic Autonomic Signaling Protocol, protocolo responsável por habilitar nós de uma rede para atuar autonomicamente. Este trabalho apresenta um estudo sobre o ANIMA, com foco na utilização do GRASP.
