Hi Team, I was going through openflow specs 1.4 and as mentioned in section 7.3.4.1. page no. 73 "If the flag OFPTMPEF_IMPORTANCE is the only flag set, eviction will be performed strictly in order of importance, that is flow entry with lower importance will always be evicted before flow entry with higher importance.", I have some queries regarding eviction behaviour.
Considering the case when Eviction is enabled on the basis of IMPORTANCE (i.e. flows of lower importance will be evicted) and the table limit is set to 5. Now suppose there are 5 flows of importance 100,101,102,103,104. Now when the new flow is entered and has IMPORTANCE=10 and as the eviction is enabled, the switch will evict flow having IMPORTANCE=100. Now is'nt this illogical to evict flow of higher importance (in this case importance=100) for the new flow of lower importance (in this case importance=10). Considering the users above importance=50 as PLATINUM user and user with importance < 50 as normal user. So for a normal user a platinum user's service will be disrupted and will suffer loss of packet (although for short period of time). Kindly explain this behaviour of openvswitch ?
