I have an check that I run before I run performance tests which sends a ping along all of the paths that I run perf testing on. It runs `ping -q -c 1 -s 1472 -M do ` from every source to every destination running an iperf server It passes. I've set the MTU on all our network devices to Just for ki

MTU? Big drops in performance numbers are usually because of packet fragmentation. Keep the MTU of your packet origin to, say 1450 and retry? On 31 July 2018 at 12:01, Carl Baldwin wrote: > My apologies. I failed to include the ovs version number that I'm using. It > is 2.7.3. Is there anything

[ovs-dev] MPLS performance question

2018-07-30 Thread Carl Baldwin
I recently tried pushing MPLS labels using OVS in a lab. Before adding MPLS push to the mix, I had four hosts: two pairs, each connected to a different set of TOR switches running VRRP. OVS (using kernel datapath) had a flow to write the VRRP mac address and output to a bond port. The bond is a Li
