The OpenDataPlane (ODP) is an open-source project which defines application programming interfaces (APIs) for the networking data plane.[1]

Networking by functionality can be defined as:

  • Data plane refers to all the functions and processes that forward packets/frames from one interface to another.
  • Control plane refers to all the functions and processes that determine which path to use. Routing protocols, spanning tree, ldp, etc. are examples.
  • Management plane is all the functions you use to control and monitor devices.

And data plane can be:

  • Software
  • Hardware
  • Software defined

OpenDataPlane set of API allows to write effective software defined data plane implementations which describe network hardware System on Chips (network SoCs) capabilities. Application built on top of ODP library are hardware agnostic, portable and use as much hardware accelerators as implementer of ODP can provide.

History

On October 29, 2013 Linaro announced that it was collaborating with members of the Linaro Networking interest Group to develop and host an open standard application programming interface for data plane applications.[2] Initially defined by members of the Linaro Networking Group, this project is open to contributions from all individuals and companies who share an interest in promoting a standard set of APIs to be used across the full range of network processor architectures available.

Technology Overview

The OpenDataPlane project is an open-source, cross-platform set of application programming interfaces (APIs) for the networking data plane.

ODP consists of an API specification and a set of reference implementations that realize these APIs on different platforms.[3] Implementations range from pure software to those that deeply exploit the various hardware acceleration and offload features found on modern networking System-on-Chip (SoC) processors.

ODP's goal is to allow implementers of the API great flexibility to exploit and optimize the implementation. This is intended to enable easy platform portability such that an application written to the API can pick up performance gains without needing significant platform knowledge when ported.

ODP is currently being used to develop reference platform implementations of Open Platform for NFV (OPNFV) [4] and is being promoted [5][6] by companies as part of their data plane support initiatives.

Products were announced by companies such as Kalray with many acronyms.[7] The OpenDataPlane run to completion execution models and framework are also being used by FastPath applications to leverage OpenFastPath functionality. DPDK is supported in the OpenFastPath release through the ODP-DPDK layer. The intent of OpenFastPath is to enable accelerated routing/forwarding for IPv4 and IPv6, tunneling and termination for a variety of protocols.[8]

Implementations

There is a Linux based reference software implementation of the ODP API, intended to be a functional model to establish the API behavior. In conjunction with a validation suite, this gives a base for accelerated implementations to extend. Current ODP implementations exist for several processors, with varying degrees of hardware offload:
