baseboxd and its OpenStack integrationTobias Jungel – NFV Workshop, 27 October 2015
Agenda
● A glimpse of Hardware acceleration● OpenStack Network 101● Yet another OpenFlow controller
Using OpenStack you get*
● Software router● Software tunneling● Software NAT
● Configure actual network hardware on your own and out of band
*) you can get more...
What you want
● Hardware Accelerated Routing● Hardware Accelerated Tunneling● Hardware Accelerated NAT● Fast Packet IO between VMs
Hardware acceleration
● Generic Purpose Processors (~DPDK)● (Net)FPGA● Network Processors● ASICs

OF-DPA
● Layer 2 Address Management● Layer 3 Management● Port and Flow Events● Port Configuration● Flow Statistics● Packet Transmit and Receive● VLAN Configuration● Tunnel Configuration (VxLAN)● MPLS Configuration (VPN, LER, LSR, TP)● QoS (classification, metering, marking,
shaping)● OAM (ITU G.8113.1 and Ethernet OAM
over MPLS-TP)

baseboxd
● Map physical switch interfaces to Linux as tap interfaces
● Send/receive packets via tap interfaces to/from switch
● Control switching tables via netlink● OF 1.3 is used as control protocol (with BCM
extensions)

What's up next?
● basebox– Finalize ML2 Plugin
– Finalize L3
– Support NAT
– OF-Config for switch configuration
– TTP to select the right driver
● OS integration– Involve nova scheduler for embedding
