Broadcom Delivers Next Generation Open Switch Pipeline Specification

OpenFlow Data Path Abstraction Version 2.0 Supports Carrier Network Applications

IRVINE, Calif., Dec. 9, 2014 — (PRNewswire) —  Broadcom Corporation (NASDAQ: BRCM), a global innovation leader in semiconductor solutions for wired and wireless communications, today announced its next generation OpenFlow Data Plane Abstraction (OF-DPA)  version 2.0 reference platform that includes OpenFlow software, specification and APIs, optimized for use in carrier networks and datacenter applications. With support for new networking protocols, the OF-DPA v2.0 reference platform allows datacenters and service providers to quickly deploy new applications and services. For more news, visit Broadcom's Newsroom.

The OF-DPA v2.0 reference platform enables service providers to provision, control, and instrument network switch elements through a standardized instruction set, based on the OpenFlow specification, APIs and its extensions. Designed to run on Broadcom's industry leading StrataXGS® chipset, the reference platform delivers on the flexibility and control requirements of large-scale carrier deployments.

"Broadcom's OF-DPA v2.0 supports emerging Software Defined Networking (SDN) use cases for service provider networks," said Ram Velaga, Broadcom Senior Vice President & General Manager, Network Switch. "The OF-DPA 2.0 feature set for the widely-deployed StrataXGS-based hardware, coupled with a rich software ecosystem, enables improved efficiency and operational agility for the largest carriers around the globe."

Broadcom's OF-DPA v2.0 reference platform enhances its previously released OF-DPA 1.0 reference platform with new carrier features including MPLS-TP, OAM and QoS and includes support for additional platforms optimized 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 resulting in cost and time efficiencies. Examples of these include requirements for a Packet Transport Network (PTN) switch and the semantics of hardware packet flows.

Broadcom's OF-DPA v2.0 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 feature-rich StrataXGS switch architecture to the OpenFlow v1.3.1 switch and pipeline while providing innovative concepts on how OpenFlow can be implemented in the most efficient way. 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 academia-based development ecosystem.

OF-DPA Version 2.0 Key Features

  • Support for MPLS-TP, MPLS L3 VPN, VLAN Translation, and QoS DiffServ per-hop behavior based on RFC-compliant Meter table extensions
  • Leverages ONF Forwarding Abstractions Working Group Table Type Patterns (TTP)
  • Scalable OpenFlow switch pipeline that efficiently utilizes ASIC resources and that supports multiple platforms
  • Significantly improves latency and throughput of flows at scale using multiple tables and leveraging intrinsic ASIC capabilities such as advanced multipath support
  • Enables popular SDN use cases such as virtual tenant networks, network virtualization, traffic engineering and service chaining

Network Operators:

Dr. Li Han, Vice Director, Network Technology Department, China Mobile Research Institute
"China Mobile has pioneered the design and implementation of packet-based transport networking (PTN) and is actively leading the introduction of SDN controls in our next-generation Super-PTN network. We are looking forward to chip level solutions and the release of OF-DPA 2.0 for transport networking is an important milestone in enabling a wide array of existing switch solutions to be rapidly deployed to meet China Mobile's Super-PTN application requirements and to unleash the full potential of OpenFlow over merchant silicon."

Original Equipment Manufacturers (OEMs):

Philippe Michelet, Director, Products and Networking, Hewlett Packard
"Broadcom's OF-DPA 2.0 software has enabled support for use cases such as MPLS-TP, OAM, and QoS, which is a significant step forward for software-defined networking. The combination of Broadcom software and HP's SDN solutions enables the agility and security that Service Providers need to deploy a distributed infrastructure."

Akio Iijima, Chief Product Architect, Converged Network Division, NEC Corporation
"NEC has worked with Broadcom to enable scalable OpenFlow 1.3-based Programmable Flow solutions on high performance ASICs for our next generation leadership datacenter products."

Nir Halachmi, Director, Strategic Product Management and Innovation, Telco Systems
"Telco Systems' ViNOX, the first carrier SDN operating system with OpenFlow support, builds on OF-DPA 2.0 and enhances it to perfectly match service providers' specific needs. OpenFlow facilitates granular visibility and control of networks while simplifying and expediting the introduction of new services. Leveraging Telco Systems long partnership with Broadcom to embrace the SDN vision of merchant ASIC based data plane with OpenFlow as the control plane, Telco Systems' ViNOX supports smooth migration from CE2.0 networks to next-generation SDN."

Original Device Manufacturers (ODMs):

George Tchaparian, Senior Vice President of R&D and Business Development, Accton Technology Corporation
"Accton is excited to add OF-DPA 2.0 and its rich set of OpenFlow-based programmable network capabilities to our family of bare-metal and OCP-compliant datacenter switches that we develop in close collaboration with Broadcom.  Accton's subsidiary, Edge-Core Networks, will deliver the enhanced programmability, openness, and services enabled by OF-DPA to enterprises, big data and service provider customers as part of Edge-Core datacenter and broadband services infrastructure solutions."

John Muller, Vice President, Sales, Advantech Networks and Communications Group
"To remain competitive, network service providers must respond to evolving traffic types and changing network demand in significantly shorter time frames than before. Broadcom's OF-DPA v2.0 reference platform brings new efficiencies to Advantech's high capacity StrataXGS-based switches enabling customers with not just a leap in performance, but an optimized OpenFlow 1.3.1 implementation for greater flexibility and control over accelerated new service provisioning."

Philippe Chevallier, Director, Product Management, Platform Architecture, Communications BU, Kontron
"As a long-standing Broadcom partner, Kontron is leveraging the OF-DPA 2.0 software package to ensure its StrataXGS-based switches provide carrier network operators the quickest and most versatile path to deploying NFV and SDN environments using the COTS-based SYMKLOUD converged cloud infrastructure platforms."

Oliver Vautrin, Head, Product Line Management, Pica8
"Pica8 is working with Broadcom to improve the capabilities and possibilities of OpenFlow-based SDN applications.
