N2 - NFV-MANO has become the de-facto standard for network service orchestrationin future programmable network infrastructures. Relevant standards definean architecture and a data model that allows an orchestration entity todeploy, dynamically configure and monitor virtual and physical networkfunctions across virtualized datacenters. Although the model offersextensive details for network function management and host-level networkconfiguration, end-to-end connectivity management beyond the datacenterremains limited. The responsibility for cross-site connectivity isdelegated to a control abstraction, the WAN Infrastructure Manager (WIM),which is partially defined in relevant standards. The referenceimplementation of the NFV-MANO standards, Open Source MANO (OSM), hasrecently released a reference WIM driver model, but no open-source WIMimplementation is currently available, thus restricting the ability ofresearchers to experiment with multi-site service deployments. In thispaper, we present the DataPlane Broker (DPB), the first open-source WIMimplementation for software-defined networks. Using an extensive datamodel, DPB seamlessly translates NFV-MANO requirements into SDNconfiguration, supporting point-to-point and multipoint connectivity withstrong bandwidth guarantees. DPB is integrated with OSM FIVE via a WIMplugin. Initial experiments highlight that path computation can scale tolarge network topologies and a large number of services, with negligiblecomputational overheads, while DPB increases by less than 10% the overalldeployment delay of an OSM service.
