Description

DPB is an extensible network management framework, offering support for the WIM abstraction in the NFV-MANO data model. The architecture of the system follows a multi-layer design approach.

At the top of the system is the aggregator layer, which is responsible for service persistence, allocation of trunk resources, and end-to-end path computation.The aggregator layer exposes a single northbound interface (NBI) to the resource orchestrator for the management of logical networks across datacenters.

The aggregator NBI can be used recursively by a top-level aggregator, in order to abstract different technological or administrative domains and offer scalability through control delegation.

The logical-switch layer constitutes the middle layer of the DPB architecture and isresponsible for persisting configuration and forwarding state for network devices. A logical switch offers the same control NBI as an aggregator. Control of the underlying network devices is achieved through the fabric adaptation layer, which translates forwarding policy into technology-specific configuration.
