Test Case: <strong>OpenFlow</strong> Switch Forwarding Test<br />
Test Case: <strong>OpenFlow</strong> Switch Forwarding Test<br />
Overview<br />
Through <strong>OpenFlow</strong> you can program data path by building the flow table in <strong>OpenFlow</strong><br />
switch. In the flow table there are two components: Match and One or more Actions.<br />
<strong>OpenFlow</strong> 1.0 specification covers 12 tuple matches as shown below.<br />
After the match, certain actions can be performed, such as forward packet to zero or<br />
more ports, modify the field, drop the packet or if no match found forward it to<br />
controller.<br />
Objective<br />
The objective of this test is to verify the ability of the <strong>OpenFlow</strong> switch to forward L2<br />
traffic. The DUT should be able to look up the Flow Table when L2 traffic is received and<br />
forward the traffic based on specified actions. In this test, initially controller will push<br />
down L2 flows with certain Match and Action parameters. Then using traffic wizard,<br />
matching traffic will be created and sent. Using the traffic statistics; switch forwarding<br />
performance will be verified.<br />
