Hi Jasvinder, The CMakelist.txt files before and after applying the patch are exactly the same and hqos plugin is already enabled but the CLI commands are still not showing. Below is the screenshot of the CMakelist.text file located at /root/vpp/src/plugins/dpdk:

Please trying enabling it first. You should see HQoS related CLIs on the console.

Nor does the vpp debug CLI have the hqos commands, e.g. in this case it should have show dpdk interface hqos placement etc. I am working on Centos 7 and have assigned 1024 2MB hugepages. I have also attached my vpp configuration file with this email. Please suggest what could be wrong and why the plugin is not loading properly.

Below is a simple topology I have implemented: First, I tested the default profile (profile 0) provided by VPP and assigned it to all 4096 pipes (users) which should give approximately 2MB (10G/4096) to each user. It worked fine for 5 users i.e. each user was assigned 2MB but for an increased number of users it didn’t work the same way. I changed the token bucket rate, token bucket size and tc_period parameters in the hqos.c code which didn’t give me any concrete results. I have attached results for 10 clients with different combinations of token bucket size, token bucket rate and tc_period. Any ideas what the problem might be ? Also, in what proportion should the tb_rate, tb_size , tc_rate and tc_period be assigned? S# Rate (Bytes per second) Token Bucket Size (Bytes) TC Period (ms) Total no of PPPoE sessions Expected Result (Cumulative average bandwidth in Mbps) Actual Result (Cumulative average bandwidth in Mbps) Comments Subport Pipe Subport Pipe Subport Pipe 1 1250000000 305175 1000000 1000000 10 40 10 24.4 8.1 vpp remains stable 2 1250000000 305175 1000000 1000000 10 60 10 24.4 12.72 vpp remains stable 3 1250000000 305175 1000000 1000000 10 100 10 24.4 11.4 vpp remains stable 4 1250000000 305175 1000000 10000000 10 40 10 24.4 12.1 vpp remains stable 5 1250000000 305175 10000000 10000000 10 40 10 24.4 12.03 vpp remains stable 6 1250000000 305175 10000000 10000000 10 100 10 24.4 2.21 vpp crashes after a few seconds 7 1250000000 305175 1000000 1000000 10 60 10 24.4 12.1 vpp remains stable Regards, Abeeha Aqeel Network Design Engineer Xflow Research Inc. +923245062309 (GMT+5) abeeha.aq...@xflowresearch.com www.xflowresearch.com From: Ni, Hongjun Sent: Monday, May 6, 2019 12:52 PM Subject: RE: [vpp-dev] HQoS Hi Abeeha, For downstream bandwidth limiting, we leveraged HQos plugin in OpenBRAS solution.

Can you please elaborate which method is being used in the OpenBRAS solution for band limiting traffic? Are you using the token-bucket algorithm as well?
