Problem Statement

2015 found SDN in the trough of disillusionment. To date most SDN adoption has been in hyper scale environments and/or large-scale service provider data centers. With production SDN deployments at 4% today, ONF launched Project Atrium with the ambition to accelerate adoption by reducing the barrier to entry into the world of SDN.

Project Atrium Enterprise is Atrium’s Enterprise distribution that tackles SDN adoption in a segment most underserved – the Enterprise. In concert with Microsoft IT it brings SDN to address some fundamental challenges that Enterprise IT organizations face today with a shift in the behavior of a global digital workforce. Round- the-globe, round-the-clock digital collaboration is a given for the increasingly mobile worker whose life is defined by social on or off campus experiences. How does Enterprise IT provide them the best in class campus experience within budget?

Atrium Enterprise addresses these challenges in a multi-phase development effort. In this first phase it addresses the Enterprise Collaboration experience by developing to IMTC specifications – a QoE (Quality of Experience) service and an Automated Diagnostics and Reporting service for real-time sensitive Enterprise Productivity Applications. The solution provides integrated wired-wireless support, a choice of Openflow 1.3 data planes and seamless brownfield migration. For the social experience on campus it brings internet-first connectivity to the Enterprise. At each campus connected by the Enterprise WAN, it drops non time sensitive internet traffic off the high-cost managed WAN onto low-cost local internet connections. This maintains the social experience on campus but frees up WAN resources for real-time sensitive Enterprise Productivity Applications and gives IT an opportunity to reduce WAN budgets, while offering a best in class on-premise experience (eg for meetings) to corporate users.

Atrium Enterprise does this in collaboration with the Enterprise Vendor Community. Vendors can differentiate the Solution either by integrating their data plane and/or by plugging-in their deployment quality software on to a flexible framework that provides the following:

  1. Interoperability on the Southbound: Expands the fundamental construct of flow objectives developed in prior Atrium releases to provide ubiquitous (part of ODL Boron and ONOS) Openflow 1.3 multi table pipeline data plane programming across qualified vendor offerings. To date it has 7 different vendor integrations with many more in the pipeline.
  2. Interoperability on the Northbound: Develops the Network Intent APIs (slated for both ONOS & ODL) as the integration interface for a multitude of Enterprise Unified Communication and Collaboration applications – VLC, Skype-For-Business (SfB) to name a few.
  3. Baseline Open Source Components: Deployment quality software components that are needed to enable the Solution. With reference to Figure 1 these are OpenDaylight components such as – Topology, Inventory, Path Computation, Flow Programming, Statistics etc.

How does this tie into ONF’s mission to accelerate SDN adoption? This distribution rallies the community and channels contributions to address a specific Enterprise use case motivated by Microsoft IT. In the future the distribution will grow to support more reference customers and more use cases. With the influence of reference customers, trial proof points and an architectural model to support vendor differentiation is designed to pave the pathway for accelerated adoption.
