6. OPNFV Brahmaputra Release
Ashok will talk about ONP. ONP is a server reference architecture that brings together key hardware and open software. These ingredients are optimized for network functions virtualization (NFV), and software-defined networking (SDN) in Telecom, Enterprise, and Cloud markets.

9. Packet processing software.intel.com/networking
Packet sanity -> CRC calculation
VLAN tag present ? -> TPID
Ingress/Egress VLAN Filtering -> MAC + Port+ VLAN membership
SRC learning -> MAC + PORT
DEST MAC Learning -> MAC + port
QOS -> PCP

12. Packet rate/Cycle calculations
40gbps -> 80 mpps Or
One packet every 12.5 ns -> pipeline cycle time
If SRAM has 2 ns cycle time
More than 6 memory look ups cannot be done

Keith Wiles will introduce us to what DPDK means, the core APIs, how it is used in NFV space.
Rashmin and Rahul will extensively talk about ho we are enabling Network Resources to be Virtualized in the Network.
They will talk about how technologies like VT-D and SR-IOV enable packets to get faster from the NIC all the way up the VMs.
Irene, Keith, Ashok and Clayne will talk about how software virtualization works. They will talk about what virtual io means and how Open vswitch uses it to switch packets up to the VM in software.
Sangjin and Josh will talk about BESS which is another open source soft switch initiative started by Berkeley.
Each of the sessions will be followed by Hands on sessions or a code walk through to give you a head start on working with these technologies.
We will end the session with performance optimization tips from MJ and how to use open source tools and Vtunes to get a sense of where your performance bottle necks are.
Last but not the least, Georgi will talk about how we at Intel Benchmark dpdk and report the performances in public.
A disclaimer, not everything is shared here because not everyone is under NDA, but we are sharing whatever is public domain knowledge.
