HKG15-301: OVS implemented via ODP & vendor SDKs --------------------------------------------------- Speaker: Ciprian Barbu, Zoltan Kiss Date: February 11, 2015 --------------------------------------------------- ★ Session Summary ★ Comparison of OVS implemented via ODP & vendor SDKs. Contrasting ODP linux-generic with the native Intel DPDK SDK and ODP implemented using the DPDK SDK on X86.

2. Agenda
● Objective
● Background
● How we did it?
● The Results
○ On Keystone 2
○ On DPDK
● Future plans

3. Objective
● Last Connect you have seen Open vSwitch
running on ODP with the linux-generic
platform
● Now we measured how it performs on real
hardware
● Two platforms were close enough to be
performance tested: Keystone 2 and Intel
DPDK

4. Open vSwitch overview

5. ● Simple netdev layer similar to netdev-dpdk
● netdev port <==> ODP pktio
● odp_pktio_recv odp_pktio_send
● no scheduling, no classification (requires
ofproto provider)
Open vSwitch

6. ● The generator (netmap-pktgen) sends 64
bytes UDP packets near line rate
● Ports and addresses are constant
● OVS forwards them to another port
● There is a sink on the other side to count the
received packets (netmap-pktgen again)
The testcase

7. ● TI Keystone 2 (66AK2H12)
● 4x ARM Cortex-A15
● 2x 1 Gbps ports on board
● ODP Keystone implementation was
done by Taras Kondratiuk
● ODP-KS2 is at v0.9, linux-generic
were made on v0.3
Keystone 2 test environment
Keystone II x86
1G
OVS Pktgen

8. Keystone 2 results

9. ● Intel 82599ES 2-port 10 Gbps NIC
● Intel i5-4570 @ 3.20GHz
● ODP-DPDK platform developed
originally by Venkatesh
Vivekanandan
● ODP API: v0.6
● ODP and OVS were tweaked up for
a week or two
Intel DPDK test environment

10. DPDK results

11. ● More thorough tests (RFC 2544-like)
● Run these tests in LAVA
● Utilize as much as possible from OPNFV’s similar project
● Optimize further OVS-ODP and ODP platforms to achieve
a near line rate performance
Future plans
