Broadcom Corporation has released its latest OpenFlow Data Plane Abstraction (OF-DPA) version 2.0 reference platform. The OF-DPA 2.0 allows data centres and service providers to quickly deploy next-gen applications and services.

The recently announced OF-DPA 2.0 enables service providers to supply, control and instrument network switch elements through a standardised instruction set, based on the OpenFlow specification, APIs and its extensions. Designed to run on Broadcom's StrataXGS chipset, the reference platform aims to deliver on the flexibility and control requirements of large-scale carrier deployments.

The OF-DPA 2.0 enhances its previously released reference platform with carrier features including MPLS-TP, OAM and QoS and includes support for additional platforms optimised for carrier use cases. Carrier network operators will now have access to the same scalable infrastructure with programming abstractions that can be automated from standard controllers. Examples of these include requirements for a Packet Transport Network (PTN) switch and the semantics of hardware packet flows.

Broadcom's latest reference platform implements the Open Networking Foundation (ONF) OpenFlow 1.3.1 specification. OF-DPA defines and implements a hardware abstraction layer that maps the StrataXGS switch architecture to the OpenFlow v1.3.1 switch and pipeline. The OF-DPA specification and API are openly published and provided with turnkey reference implementation on Original Device Manufacturers (ODM) and Open Compute Project (OCP)-compliant switches to enable a community and academe-based development ecosystem.
