[vpp-dev] Query on Inner packet Fragmentation and Reassembly

Hi , We have a use case, where we receive packets in a tunnel, and the inner packet may be fragments. If we want to reassemble the inner fragments and get one single packet, does VPP already have a framework that has this functionality. If it's already there, we can make use of it. I saw MAP pl

Re: [vpp-dev] Query on Inner packet Fragmentation and Reassembly

Hi Murthy, yes it does. Code is in ip4_sv_reass.c or ip4_full_reass.c. First one is shallow reassembly (as in, know 5 tuple for all fragments with having to actually reassemble them), second one is full reassembly. Regards, Klement > On 1 Jul 2020, at 14:41, Satya Murthy wrote: > > Hi , > >

[vpp-dev] Vectors/node and packet size

Greetings, This is my first post to the forum, so if this is not the right place for this post please let me know. I had a question on VPP performance. We are running two testcases, we limit it to single threaded and just using one core in order to reduce as many variables as we can. In the tw

Re: [vpp-dev] Vectors/node and packet size

In order for the statistics to be accurate, please be sure to do the following: Start traffic... “clear run”... wait a while to accumulate data... “show run” Otherwise, the statistics will probably include a huge amount of dead airtime, data from previous runs, etc. HTH... Dave From: vpp-dev@l

Hi, You're seeing this issue because vpp_echo is trying to use the old connection mechanism. The configuration I typically run with is the following [1] And launching vpp_echo with : ./vpp_echo socket-name /var/run/vpp.sock server uri tcp://10.0.1.1/1234 ./vpp_echo socket-name /var/run/vpp.sock cl

Re: [vpp-dev] failed to init shmem: tcp_echo server not working

As replied on the private thread, vpp-echo needs to know about the api prefix you’ve configured (vpp1). Try adding “chroot prefix vpp1” to the list of options. Regards, Florin > On Jul 1, 2020, at 10:46 AM, sadhanakesa...@gmail.com wrote: > > also i tried to get use-svm-api in existing kernel

Hi Team, I realized that memif and corresponding sockets are tightly coupled. Means for example memif1 --> /run/vpp/memif1.sock --> application. We can not have multiple sockets for memif1, is my understanding correct? memif1 --> /run/vpp/memif1.sock if its already mapped, then we can not create m
