I would like to ask more about eviction policy of OpenFlow Flow's Table
1. If I don't specify the groups field, which entry will be removed?
All flows are put into a single group, and then eviction proceeds in the
manner documented in ovs-vswitchd.conf.db(5).
2. If all flows has the same idle timeout value, is it similar to
LRU ? the least recently used flow (will be expired soonest) will be
remove ? I did an experiment but it seems not true.
Behavior should approximate LRU. What behavior did you see?
I inserted entries that match source IP addresses and generate packet
with various source IP addresses (following Zipf's distribution) However
the entry for popular packets is removed too many times than I expected.
I will double check it.
Thank for your answer.
