Re: [vpp-dev] VPP - mechanism to drop packets

Thank you Dave, The drop is working perfectly But the other path - to let the packet continue in the 'normal' path is broken. How to set the next0 for the 'normal' path ? The sample plugin (which my plugin is based on) set it to INTERFACE_OUTPUT - which is not suitable for this case. Btw - h

Re: [vpp-dev] TCP Proxy Through-put

Hi Shaun, Glad to see you’re experimenting with the proxy code. Note however that the implementation is literally just a proof of concept. We haven’t spent any time optimizing it. Nonetheless, it would be interesting to understand why this happens. Does the difference between apache and vpp

[vpp-dev] TCP Proxy Through-put

Hi, We are doing some basic testing using the TCP proxy app in stable-18.01 build. When I proxy a single HTTP request for a 20MB file through to an Apache web server I get less than one-tenth of the throughput compared to using a Linux TCP Proxy (Apache Traffic Server) on exactly the same setup

Re: [vpp-dev] VPP As A Router Between Namespaces - 10ms latency

“show run” will probably show a very small vector size. If so, look at src/vlib/unix/input.c:linux_epoll_input(…). 10ms is exactly the epoll_pwait timeout value. D. From: vpp-dev@lists.fd.io On Behalf Of Sara Gittlin Sent: Wednesday, March 7, 2018 2:02 PM To: vpp-dev@lists.fd.io Cc: vpp-dev@li

Could you try again with taps and large rings? create tap rx-ring-size 4096 tx-ring-size 4096 create tap rx-ring-size 4096 tx-ring-size 4096 Configure then the two taps in your namespaces and run iperf again. Hope this helps, Florin > On Mar 7, 2018, at 11:01 AM, Sara Gittlin wrote: > > Th

Thank you Hau i tested w iperf got similar results. I cannot find iperf2. Anyway ns to ns directly without vpp is perfect 50 gbps throughput and 10us latency. Tested w iperf3. This is very bothering since we decided to go w vpp instead of ovs Thanks in advance -Sara בתאריך 6 במרץ 2018 20:00,‏ "H

Looking to confirm worker_thread creation/deletion capabilities. ./src/vpp/conf/startup.conf descriptions suggest we must define the number of worker_threads up front. I am looking to understand if that is correct, or if we can add/remove worker_threads from a live system over time as workloads

Re: [vpp-dev] route creating performance issue because of bucket and memory of adj_nbr_tables

Hi Lollita adj_nbr_tables is the database that stores the adjacencies that represent the peers attached to on a given link. It is sized (perhaps overly) to accommodate a large segment on multi-access link. For your p2p GTPU interfaces, you could scale it down, since there is only ever one peer

Re: [vpp-dev] VPP - mechanism to drop packets

Dear Avi, Yes, if you decide to drop b1, set next1 / error1 in the obvious way. The macros vlib_validate_buffer_enqueue_x[2|4] sort out the various incorrect speculative enqueue / 2 or 4 pkts going to different successor node cases. Simply set (nextN, errorN) as desired and let the boilerplate
