Basics of ODL

Highlighted results

Other results

Conclusions

Open Source SDN Controller

Modular architecture

No time for all, highlight selected

Openflow NB/SB perf, scale, longevity

And some we will not have time to cover

NetVirt, NETCONF NB, NETCONF scale, OVSDB, BGP, PCEP...

Program OF flow rules in OVSs as quickly as possible

Tools: Bulk-o-Matic, Mininet

Program 100k flows via ODL NB REST API

Spread across 100 OVS via Mininet

Wait until all stats returned, flows verified

Results: 17k flows/s

Similar test in CI

Program OF flows to OVSs via ODL NB until ODL breaks

Tools: Bulk-o-matic, Multinet or MT-CBench

Results: 5k OVSs, 1M flows

Add OF rules to ODL data store, restart OVS net, re-program

Similar to "OpenFlow NB Rate" tests, +restart

Removes NB REST API from test, focus on OpenFlow Plugin

Tools: Bulk-o-matic, Mininet

Program 32 OVSs with 100k flows total via ODL NB, restart net

Results: Re-program and verify in 4 seconds, 25k flows/s

OVSs connected to ODL and sending pkts for 12 hours

Tools: NSTAT, Multinet or MT-CBench

Connect 16 networks of 200 OVSs to ODL = 3200 OVSs

Send OF PKT_INs in latency mode

Early versions of this test found bug 1395

Results: Stable at 100k flows/s with 3200 OVSs for 12 hours

Connect OVSs to ODL until ODL breaks

Tools: NSTAT, Multinet or MT-CBench

Results: 16 Mininets * 400 OVSs = 6400 OVSs

Connect OVSs to ODL, remove them, repeat

Add 200, verify, remove 200, verify

Results: Stable for at least 2 days

There are many types of performance tests

Big community of people running in labs and CI

ODL's perf/scale/longevity is quite good

Primary take-away: Likely good enough for your usecase
