Introduction

WIM is the acronym for WAN Infrastructure Manager, which is a specialized VIM that allows to establish connectivity between different network endpoints at different NFVI-PoPs in the context of a multi-site service Wide Area Network (WAN).

For the establishment of the network connectivity, the WIM may rely on network controllers that handle the fulfilment of the connectivity at a lower level, potentially making use of different network technologies and protocols. The WIM offers to the consumers an abstraction of such network connectivity to ease the provisioning and monitoring of it.
