  - "In recent years, a variety of different approaches\r\nhave been proposed to tackle
    the problem of scaling and placing\r\nnetwork services, consisting of interconnected
    virtual network\r\nfunctions (VNFs). This paper presents a placement abstraction\r\nlayer
    (PAL) that provides a clear and simple northbound interface\r\nfor using such
    algorithms while hiding their internal\r\nfunctionality and implementation. Through
    its southbound interface,\r\nPAL can connect to different back ends that evaluate\r\nthe
    calculated placements, e.g., using simulations, emulations, or\r\ntestbed approaches.
    As an example for such evaluation back ends,\r\nwe introduce a novel placement
    emulation framework (PEF)\r\nthat allows executing calculated placements using
    real, containerbased\r\nVNFs on real-world network topologies. In a case study,\r\nwe
    show how PAL and PEF facilitate reusing and evaluating\r\nplacement algorithms
    as well as validating their underlying\r\nmodels and performance claims.@eng"
