Destravando o Element Management System: Permitindo a Gerência Holística de Funções de Rede Virtualizadas
Abstract
The development of efficient management solutions is a fundamental step towards the broad adoption of Network Function Virtualization (NFV) technology. The Element Management System (EMS) is a key component of the NFV reference management architecture defined by the European Telecommunications Standards Institute – ETSI. The EMS actuates directly on the Virtualized Network Functions (VNF), executing operations issued by the VNF Manager (VNFM) and Operation and Business Support Systems (OSS/BSS). In recent works however, the EMS has been either (i) completely ignored or (ii) employed in limited settings, typically for executing simple operations in the context of a particular application. In this work, we propose a comprehensive EMS architecture that is compliant with the NFV reference architecture. This architecture enables the creation of a holistic EMS to manage VNF instances while abstracting communication protocols and technologies, allowing the interoperability among different VNF platforms and OSS/BSS. A prototype was implemented, and evaluation results are presented for the overhead of including the EMS in the execution of typical management operations.
