HPE SDN Roundtable Insights
HPE recently organized two series of roundtable discussions at the OpenDaylight Summit in Seattle and at the SDN and OpenFlow World Congress 2016 in The Hague, Netherlands. At both events, a diverse set of network operators, open source developers and integrators, NFV and SDN experts, leading analysts, and vendor representatives came together to discuss key industry topics.
The conversations at OpenDaylight Summit focused on today’s software-defined networking (SDN) and network functions virtualization (NFV) deployments—specifically, the overlay/underlay problem, brownfield vs. greenfield deployment, skill set and recruiting, and SDN monetization. At SDN OpenFlow World Congress, key themes included experiences in recent NFV deployments, the limits of virtualization, complexity management, and MANO and OSS integration—all timely and pertinent topics for those in the community evaluating NFV or deploying NFV.
As a service to the community and to spark further discussions, SDxCentral has published reports on both series of roundtable discussions. These reports include anonymized viewpoints of leaders in the SDN and NFV ecosystem, as well as examples of successful or unsuccessful deployments in the community. They do not endorse the products, services, or companies by HPE, the Linux Foundation, the OpenDaylight Project, or SDxCentral.
The thrust of the OpenDaylight Summit document is SDN operations, deployment, orchestration, and pricing and monetization of open source. In the operations realm, SDN is seeing traction in SD-WAN and SGi/Gi-LAN, although skills and training continue to be a challenge to SDN’s uptake. As for SDN deployment, the problem of overlay/underlay coordination or non-coordination will continue to be an issue. Further, best practices for a tiered controller and federated controllers will take significant discussion and time to resolve. On the topic of orchestration, VMware and proprietary systems will dominate when deployment timeframes are short, although that mindset is changing as open source solutions mature, and the challenge will be to coordinate between the two. Finally, many monetization schemes are still being explored for open source, but there’s no consistency in monetization methods yet. Read the specifics:
The focus of the SDN World Congress document is NFV use cases and SDN-enabled NFV use cases. The NFV use cases find many CSPs looking at building the next generation of NFV infrastructure for larger-scale deployments. Challenges that CSPs face include managing between PNFs and VNFs, workload sizing, placement and optimization, and process and cultural barriers. As for the SDN factor, SD-WAN and vCPE are popular enterprise use cases with clear business value, with SD-WAN offering CSPs the promise of value-added services as a managed service for the enterprise.
