The ARM® 64-bit architecture is rapidly emerging as a standard ISA spanning all segments of the networking space, bringing the industry closer to having a single standard platform for networking and network function virtualization (NFV). The Linaro engineering organization is dedicated to the consolidation of open source software and tools for the ARM ISA, focused on building a robust ecosystem around a single runtime software platform. The primary activities of the networking working group of Linaro will be examined, including the role, objectives and activities of Open Dataplane -- an effort to create a platform independent and vendor-neutral standard API for optimized packet processing for NFV and traditional networking services, and its relationship to activities such as the Open Platform for NFV (OPNFV) initiative.
