OK. We haven't characterized OVS latency in such fine detail. I encourage you to investigate, but I will not look into this myself. On Sat, Mar 16, 2019 at 02:48:37AM +, sunquanying wrote: > “Delay shaking” means that ping6 delay is between 0.05ms and 0.1ms most of > the time. A few

[ovs-discuss] 答复: ping6 delay shaking with nd_target

2019-03-15 Thread sunquanying
“Delay shaking” means that ping6 delay is between 0.05ms and 0.1ms most of the time. A few minutes later, ping6 delay suddenly bigger than 0.3ms, and after one or two packets, ping6 delay is between 0.05ms and 0.1ms again. The time interval of ping6 delay suddenly increase has no rules.

You should not need to match on both labels to pop a single label. If you use ofproto/trace for this packet (see ovs-vswitchd(8)), what does it say? On Tue, Mar 12, 2019 at 08:34:38AM -0400, Thomas Crowley wrote: > I am attempting to pop the outer MPLS label on a packet that has two MPLS >

Hi, On my Fedora 29 when ever I run all the ovs tests with "-j5", I see few core dumps generated for ovsdb-server and python2. Here's the back trace [root@nusiddiq ovsdb]# gdb ./ovsdb-server /opt/core_dumps/core.ovsdb-server.24604 GNU gdb (GDB) Fedora 8.2-6.fc29 ... ... Core was

Sounds like a great plan, Ben! Thanks for that. It'd be great if people could chime in this thread to help identify those gaps. As about the anecdotes, we had just been involved in a case where OVN was used and packets were dropped at conntrack: Two VMs on different Logical Switches (externally

Hi What I know is EMC need more memory space. EMC has 8k entries by default, this memory can store 1000K SMC entries. EMC should perform better with the same cache entries, but SMC is better with the same memory space. Best Regards, Wei Yanqin -Original Message- From: txfh2007 Sent:

Hi Yanqin && all: I have studied this ppt && vedio, and tried in my own environment. The result is in 100K mac-ip PVP test scenario, when EM_FLOW_HASH_SHIFT == 17(emc entry num is 130K+), the performance can still maintain(a little decline than 10K mac-ip scenario). My formal conclusion is
