    multiple administrative domain (aka multi-domain) orchestration
    models. Based on a new broker-plane approach on top of per-domain
    management and orchestration functions, we present a Multi-domain
    orchestration prototype capable to coordinate the delivery of a
    multi-operator End-to-End Network Service (E2ENS) that combines
    per-domain paths and network functions for a given service request.
    Our prototype implementation retrieves local information about
    topology and resources from each Multi-domain Orchestrator (MdO) to
    offer after inter-domain added value services in the form of abstract
    Map Services. These map abstractions are easily consumable through
    developer-friendly REST APIs based on the Application-Layer Traffic
    Optimization (ALTO) standard protocol.",
