Linaro Networking Group - What Has Been Happening?

3 mins read

Linaro Networking Group (LNG) has been very busy.  During the week of Linaro Connect USA (LCU14) the team had many activities that took place.   On the Thursday of Connect there were some surprising demonstrations involving OpenDataPlane (ODP) in the LNG hacking room. Surprising because of the breadth of multiarchitecture platforms (include Arm, MIPS and x86) as well as functional ODP applications that showed bare metal performance running in userspace on Linux. ODP has come a long way since LCA14. If you were not able to attend, here’s a recap of the LNG activities, sessions and demos during the show as well as an interview with the team’s Director discussing the activities the team has been working on and what is coming up.

  • Keynote Title:  “NFV: Empowering the Network”  by Dr. Christos Kolias - Senior Research Scientist at Orange

Keynote Abstract: 

Network Functions Virtualization (NFV) envisions and promises to change the service provider landscape and has emerged as one of one of today’s significant trends. Although less than two years old, NFV has garnered the industry’s full attention and support. Moving swiftly, a number of key accomplishments have already taken place, and a lot more work is currently under way within ETSI NFV while we are embarking on its future phase. Various proofs-of-concepts (ranging from vEPC to vCPE, vIMS and vCDN) are being developed while issues such as open source and SDN are becoming key ingredients as the can play a pivotal role.

Demos at Linaro Connect

In the time leading up to Connect LNG engineers were kept busy in getting their engineering demos ready for LCU14. Demos included APM, Avago, Cavium, Freescale & TI platforms running OpenDataPlane (ODP) with various applications, covering Armv7 & v8, X86, MIPS64 and PowerPC. In addition to Cisco’s own DataPlane & crypto application, Open vSwitch, Wireshark, Open DayLight, and Snort were run to demonstrate its functional capability.
