[vpp-dev] Developing application on top of VPP

[Shashi Kant Singh]

Hi

There is a need to port AI kind of application on top of VPP. This could > 20k 
lines of code with fair complexity.
Would it make sense to put this as plugin in VPP or have an independent 
application and connect to VPP using VCL?
Does it mean that AI app need to be broken down in 10 of nodes if plugin is the 
option?

Performance required from AI app is like that of a typical data path.

Regards
Shashi

[Ray Kinsella]

Would be good if you could provide some additional information.

What kind of application is it - UDP/TCP/RAW socket based?
How is it typically deployed - Cloud Based, Virtualized Appliance or 
Discrete Appliance?

SKS: Would be a mix of UDP/GTP and TCP/SCTP. UDP/GTP over IPSEC.

How is it typically deployed - Cloud Based, Virtualized Appliance or Discrete 
Appliance?
SKS: Cloud Based in a VM.

[vpp-dev] stats mess

[Klement Sekera]

Hi,

While doing some testing I noticed that vpp ends in a strange state when doing 
a specific stats dance:

1. want_interface_simple_stats
2. disconnect
3. connect
4. want_stats
5. disconnect
6. connect
7. want_interface_simple_stats

Now what happens is that vpp sends combined interface counters, though only 
simple were requested. It seems that using ~0 as item in various stats 
registration contexts, while reusing code for simple/combined counters doesn't 
play well if combined. If after 5.) you put a breakpoint on 
do_combined_interface_counters(), you'll see that it's called regularly even 
though the client is gone now...

This was seen with VAPI unit test and doing an explicit want_stats with 
enable_disable=0 workarounds the issue. I've added such fix, but I still think 
this should be fixed.

Regards,
Klement

I do not see this second issue.

This might be specific to the deb packaging.


Please try build or build-release targets first.

Hi John,
I have Downgraded Qemu and Libvirt to atleast make VM UP.
ubuntu@ubuntu:~$ virsh -c qemu:///system version --daemon
setlocale: No such file or directory
Compiled against library: libvirt 1.3.1
Using library: libvirt 1.3.1
Using API: QEMU 1.3.1
Running hypervisor: QEMU 2.5.0
Running against daemon: 1.3.1

ubuntu@ubuntu:~$ 

Commented "nodaemon" and added "interactive" in startup.conf but gid vpp were 
in 2 places unix and api-segment.
When only in unix its commented then vpp starts but interface does'nt come up 
And when i comment either in api-segment or both then vpp will fail to start,
I am attaching both the Logs below, pls go through and let us know about this 
issue.

Also using Qemu and Libvirt to latest is failing to bring up VM itself.
I am using Latest Qemu 2.11 and since i am using Virsh i updated Libvirt to 
latest 3.6.0 (Ubuntu 16.04)ubuntu@ubuntu:~$  virsh -c qemu:///system version

Both versions were ideally not having an official release for ubuntu 16.04.


But when i try and do virsh-install it'll get stuck after boot maybe crash same

Hi Adarsh,
 
  
 
Would you be able to try the following?
 
  
 
In startup config for now, could you add the following change in the unix 
section of the vpp startup.
 
  
 
  # nodaemon
 
  interactive
 
  
 
Also, I see you have the line gid vpp. I am not sure what that does. Most of 
the configs I see do not have that. You could try removing that line.
 
  
 
Then run VPP manually like this so we might get more error information.
 
  
 
# cat /proc/meminfo – Be sure you still have some hugepages, sometimes if dpdk 
crashes it doesn’t return them.
 
# service vpp stop
 
# ps -eaf | grep vpp – Make sure there are no other VPP processes still running
 
# /usr/bin/vpp -c /etc/vpp/startup.conf
 
  
 
Then send us the results from the entire startup.
 
  
 
Thanks,
 
  
 
John

Re: [vpp-dev] Error when trying to add interface to vpp on ARM server.

[John DeNisco]

Can you do the same, but as root.

sudo /usr/bin/vpp -c /etc/vpp/startup.conf

Also, gid vpp can be in the api-segment.

I have attached my startup.conf for reference. You don’t need the dpdk section.

[vpp-dev] vpp_main with iperf3 not working #vpp

[swathins079]

Hi all,

Had anyone tried the newer version of vpp with iperf3?

When I tried the latest release of VPP, I am getting some weird result. The 
vpp_main is using 100% CPU(suspecting that it is going into a never-ending 
loop). I tried the router namespace example just to check the VPP performance 
with namespaces. Link: namespace with vpp ( 
https://wiki.fd.io/view/VPP/Configure_VPP_As_A_Router_Between_Namespaces )

OS: centos 7
CPU: intel's i5 4cores
Ram: 32GB

Tried the same with an older version of VPP in Ubuntu, this time the iperf3 
client gets timed out.

Whats wrong with VPP? Is this a known issue? JIRA for this issue is created?

Regards,
Swathin

Hello All,
I'm a vpp newbei.
I want to activate some existing plugins - i see that many of them are
loaded (e.g, acl, flowprob )  but I cannot  activate them.
another question is - I understand that i can customize  the code of
these plugins examples - correct ?

Thank you in advance
- Sara

Re: [vpp-dev] stats mess

[Dave Wallace]

Hi Klement,

Thanks for the bug report.  Could you please submit a Jira for this so 
it doesn't get lost?


Thanks,

Hi,

While doing some testing I noticed that vpp ends in a strange state when doing 
a specific stats dance:

1. want_interface_simple_stats
2. disconnect
3. connect
4. want_stats
5. disconnect
6. connect
7. want_interface_simple_stats

Now what happens is that vpp sends combined interface counters, though only 
simple were requested. It seems that using ~0 as item in various stats 
registration contexts, while reusing code for simple/combined counters doesn't 
play well if combined. If after 5.) you put a breakpoint on 
do_combined_interface_counters(), you'll see that it's called regularly even 
though the client is gone now...

This was seen with VAPI unit test and doing an explicit want_stats with 
enable_disable=0 workarounds the issue. I've added such fix, but I still think 
this should be fixed.

Klement

Hi Kawshik,

VPP is supported in ODL through Netconf/Yang.
See the Honeycomb subproject for more information.

Re: [vpp-dev] Developing application on top of VPP

[Ray Kinsella]

Really it depends on the kind of application you want to develop?

If your intention is to do something monolithic like a tightly 
integrated VNF application. A VNF with L2, L3, L4 and app as an 
integrated appliance. Then the plugin _might_ make the sense for you, 
however I suspect that VCL library might still be easier to maintain and 
integrate with in this instance


However if you intend to use a vSwitch on the system or you anticipate 
that a vSwitch will be used in the system. You can integrate the L2, L3 
and L4 with the (VPP) vSwitch and have your App sit on VCL. This ends up 
being simplier and more lightweight, but you need to know that VPP can 
be your vSwitch.


Thanks,


Ray K

Would be good if you could provide some additional information.

What kind of application is it - UDP/TCP/RAW socket based?
SKS: Would be a mix of UDP/GTP and TCP/SCTP. UDP/GTP over IPSEC.

How is it typically deployed - Cloud Based, Virtualized Appliance or Discrete 
Appliance?
SKS: Cloud Based in a VM.

Hi

There is a need to port AI kind of application on top of VPP. This

Would it make sense to put this as plugin in VPP or have an
independent application and connect to VPP using VCL?

Does it mean that AI app need to be broken down in 10 of nodes if
plugin is the option?

Performance required from AI app is like that of a typical data path.

If you also dump the memif socket table you should see
that socket-id 0 is the default socket filename.

Which means ...

 you can neither create nor delete that socket-id 0.

That might be an issue...  And it might be localized to VAT because:

vpp# create memif socket id 1 filename /tmp/foo.sock
vpp# show memif
sockets
  id  listenerfilename
  0   no  /run/vpp/memif.sock
  1   no  /tmp/foo.sock

I'll peer at VAT unless John Lo beats me to it. :-)

Re: [vpp-dev] Developing application on top of VPP

[Shashi Kant Singh]

Thanks Ray

I could see that at VPP, I could receive at line rate of 10G, process and send 
out the traffic (macswap)

When I tried to use the test_server / test_client (vcl_test_client), I could 
not go beyond 3.5G rate in stream test mode. It is probably because of VCL 
sockets being used to send and receive SINGLE packets at the vcl_test_client . 
It does not do multiple packet processing like VPP does.

How would  I get near line of packet send /receive using VCL in my application ?
I see recvmmsg kind of function in VCL but it is still not implemented using 
vpp library.

Regards
Shashi

Really it depends on the kind of application you want to develop?

If your intention is to do something monolithic like a tightly integrated VNF 
application. A VNF with L2, L3, L4 and app as an integrated appliance. Then the 
plugin _might_ make the sense for you, however I suspect that VCL library might 
still be easier to maintain and integrate with in this instance

However if you intend to use a vSwitch on the system or you anticipate that a 
vSwitch will be used in the system. You can integrate the L2, L3 and L4 with 
the (VPP) vSwitch and have your App sit on VCL. This ends up being simplier and 
more lightweight, but you need to know that VPP can be your vSwitch.

Thanks,


Ray K

[vpp-dev] Building gtpu plugin alone

[Shashi Kant Singh]

Hi

I usually use make build / build-release to build the VPP. I just need to 
modify gtpu plugin directory. How do I build that alone?

Regards
Shashi

[vpp-dev] How to activate the sample plugins

[Sara Gittlin]

Hello All,
Resending this -my last mail was broken by other  issues
I'm a vpp newbei.
I want to activate some existing plugins - i see that many of them are
loaded (e.g, acl, flowprob )  but I cannot  activate them.
another question is - I understand that i can customize  the code of
these plugins examples - correct ?

Thank you in advance
- Sara

Re: [vpp-dev] Developing application on top of VPP

[Florin Coras]

Shashi, 

You can’t really compare macswap with a full fledged host stack. As you 
delegate more work to vpp, you should expect a drop in throughput.

Also worth noting is that the stack sends/receives byte streams, not single 
packets and up to transport layer, it does make use of vectorization. The 
amount of bytes transferred per call depends on the size of the fifos and app 
buffers used. Depending on your hardware, the builtin echo client/server can 
push more than 10Gbps/connection. If you use more connections in parallel, you 
should be able to go over 20Gbps.
