Hello people, I apologise for my stupid questions. I am learning to my best.
Let me re frame my question in a better way. I want to know about the granularity of flow matching in the EMC. Here I have observed and read some facts about the matching flow. Can you please help me correct if I am wrong. *1. The below packet arrived, from these header field's miniflow will be extracted, right?* * |dpif_netdev(pmd8)|DBG|packet: tcp,vlan_tci=0x0000,dl_src=00:00:00:00:00:01,dl_dst=00:00:00:00:00:02,nw_src=10.0.0.3,nw_dst=10.0.0.4,nw_tos=0,nw_ecn=0,nw_ttl=64,tp_src=35963, tp_dst=45629,tcp_flags=ack tcp_csum:f470* *2. I am confused a bit on this point, miniflow_extract() will output a map by setting 1s for the fields extracted. Fields extracted in this case will be which fields? Are those dl_src,dl_dst, nw_src, nw_dst, nw_ttl, tp_src, tp_dst,tcp_flags tcp_csum , omitting nw_tos and nw_ecn? If yes, EMC Cache has an entry which is referencing to the flows containing all these fields?* Please help me with this, I want to confirm and clear this before I share my knowledge with anyone else as I don't wanna provide my wrong input to anyone and this mailing list is the only hope. Thank you so much. ------ Forwarded message ---------- From: Krish <attkillro...@gmail.com> Date: Mon, Apr 16, 2018 at 1:05 PM Subject: Regarding Matching Flows in EMC Cache To: ovs-discuss@openvswitch.org Hi Everyone >From Debug information of EMC Processing , I can see the packets have IPs as well as Ports. Packet information is below : *|dpif_netdev(pmd8)|DBG|packet: tcp,vlan_tci=0x0000,dl_src=00:00:00:00:00:01,dl_dst=00:00:00:00:00:02,nw_src=10.0.0.3,nw_dst=10.0.0.4,nw_tos=0,nw_ecn=0,nw_ttl=64,tp_src=35963,tp_dst=45629,tcp_flags=ack tcp_csum:f470* >From the above packet, are all the fields that are displayed will be used to search in EMC Cache including checksum? Please correct my knowledge. Regards and Thanks
