NetVirt, NETCONF NB, NETCONF scale, OVSDB, BGP, PCEP...
OpenFlow NB Rate
OPENFLOW NB RATE
Program OF flow rules in OVSs as quickly as possible
OPENFLOW NB RATE
Tools: Bulk-o-Matic, Mininet
OPENFLOW NB RATE
Program 100k flows via ODL NB REST API
OPENFLOW NB RATE
Spread across 100 OVS via Mininet
OPENFLOW NB RATE
Wait until all stats returned, flows verified
OPENFLOW NB RATE
Results: 17k flows/s
OPENFLOW NB RATE
OpenFlow NB Scale
OPENFLOW NB SCALE
Program OF flows to OVSs via ODL NB until ODL breaks
OPENFLOW NB SCALE
Tools: Bulk-o-matic, Multinet or MT-CBench
OPENFLOW NB SCALE
Results: 5k OVSs, 1M flows
OPENFLOW NB SCALE
OpenFlow SB RAte
OPENFLOW SB RATE
Add OF rules to ODL data store, restart OVS net, re-program
OPENFLOW SB RATE
Similar to "OpenFlow NB Rate" tests, +restart
OPENFLOW SB RATE
Removes NB REST API from test, focus on OpenFlow Plugin
OPENFLOW SB RATE
Tools: Bulk-o-matic, Mininet
OPENFLOW SB RATE
Program 32 OVSs with 100k flows total via ODL NB, restart net
OPENFLOW SB RATE
Results: Re-program and verify in 4 seconds, 25k flows/s
OPENFLOW SB RATE
OpenFlow SB Stability
OPENFLOW SB STABILITY
OVSs connected to ODL and sending pkts for 12 hours
OPENFLOW SB STABILITY
Tools: NSTAT, Multinet or MT-CBench
OPENFLOW SB STABILITY
Connect 16 networks of 200 OVSs to ODL = 3200 OVSs
OPENFLOW SB STABILITY
Send OF PKT_INs in latency mode
OPENFLOW SB STABILITY
Early versions of this test found bug 1395
OPENFLOW SB STABILITY
Results: Stable at 100k flows/s with 3200 OVSs for 12 hours
OPENFLOW SB STABILITY
OpenFlow Switch Scale
OPENFLOW SWITCH SCALE
Connect OVSs to ODL until ODL breaks
OPENFLOW SWITCH SCALE
OPENFLOW SWITCH SCALE
Results: 16 Mininets * 400 OVSs = 6400 OVSs
OPENFLOW SWITCH SCALE
OVS Add/remove Longevity
OVS ADD/REMOVE LONGEVITY
Connect OVSs to ODL, remove them, repeat
OVS ADD/REMOVE LONGEVITY
Add 200, verify, remove 200, verify
OVS ADD/REMOVE LONGEVITY
Results: Stable for at least 2 days
OVS ADD/REMOVE LONGEVITY
Conclusions
CONCLUSIONS
There are many types of performance tests
CONCLUSIONS
Big community of people running in labs and CI
CONCLUSIONS
ODL's perf/scale/longevity is quite good
CONCLUSIONS
Primary take-away: Likely good enough for your usecase
