Welcome to Unimgr

Introduction

The User Network Interface (UNI) Manager project within OpenDaylight provides data models and APIs that enable software applications and service orchestrators to configure and provision connectivity services; in particular, Carrier Ethernet services as defined by MEF Forum, in physical and virtual network elements.

MEF has defined the Lifecycle Service Orchestration (LSO) Reference Architecture for the management and control of domains and entities that enable cooperative network services across one or more service provider networks. The architecture also identifies LSO Reference Points, which are the logical points of interaction between specific functional management components. These LSO Reference Points are further defined by interface profiles and instantiated by APIs.

The LSO Reference Architecture is shown below. Note that this is a functional architecture that does not describe how the management components are implemented (e.g., single vs. multiple instances), but rather identifies management components that provide logical functionality as well as the points of interaction among them.

Unimgr provides support for both the Legato as well as the Presto interfaces. These interfaces, and the APIs associated with them, are defined by YANG models developed within MEF in collaboration with ONF and IETF. For more detailed information on these YANG models and the corresponding APIs, see the User Network Interface Manager Plug-in (Unimgr) User Guide.

An application/user can interact with Unimgr at either the Legato (i.e. service orchestration) or the Presto (i.e. network resource provisioning) layer.
