Collaboration aims to advance embedded ARM/Linux networking

Feb 20, 2013 — by Rick Lehrbaum 165 views

The nonprofit Linaro organization has formed a multi-company group with the goal of advancing the use of ARM-powered Linux devices in cloud and mobile infrastructure applications. Initial members of the Linaro Networking Group (LNG) include AppliedMicro, ARM, Enea, Freescale, LSI, MontaVista, Nokia Siemens Networks, and TI.

According to Linaro, many ARM-based chipsets are at the heart of the transformation currently occurring in cloud and mobile infrastructure applications such as switching, routing, base-stations and security.

“Networking infrastructure is undergoing a transformation driven by the ramp in diverse data being moved through disparate networks to and from billions of diverse devices,” states Linaro. “The industry needs to simplify the management of the network as well as create new applications that will enable cloud service providers, carriers and others to reliably provide a great user experience across expanded mobility use cases and the increasing globally-connected intelligence of devices. Enterprises need to scale their networks and their network management capabilities to cope with these demands and also enable the rapid evolution of applications for new revenue-generating business models. LNG will accelerate this transformation through its initial focus on fundamental optimizations for use across all ARM-based networking infrastructure equipment.”


The LNG will focus on consolidating and optimizing common software for networking equipment applications using ARM SoCs. Initial areas of focus include:

  • Virtualization support with considerations for real-time performance, I/O optimization, robustness and heterogeneous operating environments on multi-core SoCs.
  • Real-time operations and the Linux kernel optimizations for the control and data plane.
  • Packet processing optimizations that maximize performance and minimize latency in data flows through the network.
  • Dealing with legacy software and mixed-endian issues prevalent in the networking space.

Linaro has been developing common core software for ARM-powered, Linux-based mobile devices since June 2010, and has now begun forming special interest groups focused on server and networking applications. First LNG software deliveries are expected 1H 2013, with monthly releases thereafter.
