OpenDataPlane is a framework for developing cross-platform user space dataplane applications, like it is the case with Open vSwitch. For this we have written a "netdev provider" based on ODP to make OVS capable to work on a variety of platforms through the abstractions provided by the ODP API. The OpenDaylight Controller's role is to manage virtual OVS switches/bridges running on top of ODP, both through a GUI web interface as well as through a series of scripts that take advantage of the REST northbound API of the OpenDaylight Controller. The video also shows how to control OVS switches through the ovs-ofctl command line tool of OVS, that is equivalent to using an externally connected controller implementing the OpenFlow specification (like the OpenDaylight Controller).
Right now the ODP netdev layer for OVS runs on linux-generic using basic socket transport, and it is scheduled to be running on linux-dpdk and linux-keystone2 ODP platforms. For the purpose of the demo the ODP netdev layer doesn't take advantage of ODP's packet scheduler, it only sends and receives packets in burst mode. For that it might be necessary to implement a dpif provider, which is one layer upper in the design of Open vSwitch.

Bob Monkman, Networking Segment Marketing Manager for ARM, shares his view on some of the essential value propositions of the ARM ecosystem that are driving the adoption of the ARM architecture in networking infrastructure. In addition, Bob speaks about trends such as Software-defined networking (SDN) and Network Functions Virtualization (NFV) that driving significant change in the sector and how the Linaro Networking Group is contributing important work, including the proposed standard data plane programming API project, OpenDataPlane, in the space.
The Linaro Networking Group marked its first anniversary at the Linaro Connect Asia. Here Bob Monkman, ARM Enterprise Segment Marketing Manager, interviews Pradeep Kathail, Cisco Chief Software Architect, Network Operating System Group, to reflect on the year's accomplishments and current activity within LNG. In addition to delivering Big Endian support in the Linux kernel, LNG launched the OpenDataPlane (ODP) project to enable data plane applications to easily port across different hardware platforms and architectures while retaining the ability to exploit hardware acceleration features unique to each platform. Pradeep discusses the importance of ODP and its relationship to other open source initiatives like OpenDaylight (ODL) as part of the larger industry trends of Software Defined Networks (SDN) and Network Functions Virtualization (NFV).

Here's the 16-core ARM Cortex-A15 processor from HiSilicon Huawei on a development board for ARM Powered Networking and Servers coming up. Hacked on in this video by Linaro Toolchain Engineer Rob Savoye (2), who now is climbing the Mount Everest. Linux kernel v3.13 is running on this board, with three SATA ports and two Gigabit ethernet ports driver ready. The BSP code will soon be upgraded to kernel v3.14 and be upstreamed in parallel. Source code and binaries are released through Linaro website. Ubuntu Server is verified on this board. In this demo, it runs a GCC toolchain native build. Linaro Toolchain Working Group plans to use this board to run multiple builds per board, to maximally saturate D01's computing and storage capability.

The BSC9132 is a highly integrated device that targets evolving microcell, picocell, and enterprise-femto base station applications. The BSC9132 device combines two e500 cores, built on Power Architecture technology, and two StarCore SC3850 cores with MAPLE-B2P baseband acceleration processing elements to address the need for a high-performance, low-cost, integrated solution that handles all required processing layers without the need for an external device except for an RF transceiver or, in a micro base station configuration, a host device that handles the L3/L4 and handover between sectors.
With primary target air interfaces for LTE-FDD/TDD and WCDMA (HSPA+), the BSC9132 programmable device supports the performance and cost requirements of up to 20 MHz single sector LTE-FDD/TDD by handling 150 Mbps downlink and 75 Mbps uplink rates, 5 MHz HSPA+ by handling 42 Mbps downlink and 11.5 Mbps uplink rates for up to 64 simultaneous users, or WiMAX at 10 MHz. The BSC9132 supports multimode operation that enables it to process LTE-FDD/TDD and HSPA+ users simultaneously.

Mark Powell, Executive Director of the Bluetooth Special Interest Group, answers my questions on Bluetooth LE (also known as BLE, also known as Bluetooth 4.0 and 4.1). Bluetooth Smart is Bluetooth LE with an application framework making it easy for applications developers to add support for the more advanced Bluetooth features. Bluetooth.com says it as "Bluetooth Smart products represent a quantum leap for Bluetooth technology, allowing billions of previously disconnected devices to join the connected world." at http://www.bluetooth.com/Pages/Bluetooth-Smart-Devices.aspx
