[ovs-discuss] ovs-dpdk: How to achieve predictable throughput?

Hi, I've been doing throughput measurements of OVS DPDK version 2.4 using two PMD threads for the datapath and I'm facing a behavior that I would like to discuss. Two blades are involved in the test setup. One blade is the traffic generator and the other one has the OVS and the VM to be tested

[ovs-discuss] What LISP-related features are supported by OVS?

Hello,I read README-lisp.md and it states that 'A LISP "map-cache" can be implemented using flows'. I wonder does this mean that the whole lisp control planeis replaced by openflow messages and flow table in OVS, and lisp control messages like map-request and map-reply  not supported by OVS. I w

Yep, we stumbled into that and it worked like a charm. We couldn't quite tell from the document if in-band is enabled or disabled by default when you install and bring up a bridge for the first time. Do you happen to know? We have machines of our own at Clemson and Utah and in CloudLab and GENI. W

So, we've found a document on in-band control for OVS. The hidden flows we see installed are exactly what the in-band control document states will be installed, including ARP flows to/from the LOCAL port's MAC a

Hi, I have a very simple topology as follows: network[Dell S4810]-24---link---1-[host w/OVS br0]-LOCAL The host with OVS has IP 192.168.1.3/24 with a route into the br0 (i.e. LOCAL) interface. We try to ping another host on the network from host 192.168.1.3, but the ping confuses our control
