Hi Jasvinder,
Yes, I am aware of that. But after applying the patch, assigning hqos-threads
and enabling hqos on interface the CLI commands don’t show.
Another issue I have encountered while using vpp version 19.01 is that VPP
doesn’t start when I assign two corelist-hqos-threads. As shown in the config
file:
unix {
nodaemon
log /var/log/vpp/vpp.log
full-coredump
cli-listen /run/vpp/cli.sock
# gid vpp
}
api-trace {
on
}
# api-segment {
# gid vpp
# }
# socksvr {
# default
# }
cpu {
main-core 2
corelist-workers 4, 20, 6, 22, 8, 24
corelist-hqos-threads 12,18
}
dpdk {
dev 0000:05:00.0 {
num-rx-queues 2
hqos
}
dev 0000:05:00.1 {
num-rx-queues 2
# hqos
}
# igb_uio
# uio_pci_generic
## Disable multi-segment buffers, improves performance but
## disables Jumbo MTU support
# no-multi-seg
## Change hugepages allocation per-socket, needed only if there is need
for
## larger number of mbufs. Default is 256M on each detected CPU socket
socket-mem 16384, 16384
## Disables UDP / TCP TX checksum offload. Typically needed for use
## faster vector PMDs (together with no-multi-seg)
# no-tx-checksum-offload
}
plugins {
path /root/vpp/build-root/install-vpp_debug-native/vpp/lib/vpp_plugins/
plugin default { enable }
}
I have installed vpp version 19.04 on bare-metal server with centos 7 as
Operating System and an Intel 10G 2P X520 NIC. What could be the possible issue?

Hi Abeeha,
In the config file, hqos thread is allocated (cpu section), and hqos is’nt
enabled on interfaces (dpdk section). In the current state, hqos needs separate
thread (other than worker threads) for scheduling function, and also,
enablement on dpdk interfaces.
Thanks,
Jasvinder

Hi Jasvinder,

I tried enabling and disabling hqos but it doesn’t work in both cases.

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

Hi Abeeha,
Looks like HQoS module is disabled in current VPP dpdk plugin (Check
CMakelist.txt). Please trying enabling it first. You should see HQoS related
CLIs on the console.

Hi Hongjun,
I applied the patch submitted to fix the API change on vpp 19.04 using
underlying dpdk 19.02, following the steps:
git clone https://gerrit.fd.io/r/vppHi Hongjun,
cd vpp
make wipe
make install-dep
make install-ext-deps
wget
https://gerrit.fd.io/r/changes/16839/revisions/a62db7f3796ef152d23475ed36ad5f3fbfcab2a8/archive?format=tar
mv archive\?format\=tar a62db7f.tar
tar -xvf a62db7f.tar
make build
./vpp -c /root/go/src/github.com/xFlowResearch/BNG/vpp-startup.conf &
./vppctl
I also tried, git fetch and cherry-pick:
cd vpp
make wipe
make install-dep
make install-ext-deps
git stash
git fetch https://gerrit.fd.io/r/vpp refs/changes/39/16839/3 && git cherry-pick
FETCH_HEAD
make build
./vpp -c /root/go/src/github.com/xFlowResearch/BNG/vpp-startup.conf &
./vppctl
In both cases, the setup builds and starts properly but hqos plugin doesn’t
work. 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.

Hi Hongjun,
I have tested the HQoS Plugin with iperf3. 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)

Hi Abeeha,
For downstream bandwidth limiting, we leveraged HQos plugin in OpenBRAS
solution.
In our previous integration test, it could support 64K subscribers with HQos.

Hi Hongjun,
I have been trying to implement downstream bandwidth limiting using HQoS plugin
in vpp. It works fine for a certain number of clients (less than 5) but doesn’t
assign proper bandwidth for larger number of clients.
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?
