Re: [vpp-dev] [csit-dev] how to know data type mapping between *.api.json with PYTHON API ?

2019-05-07 Thread Ole Troan

Hi Yulong,

Good question. That has been on my list of things to document for a while.
Does 
https://gerrit.fd.io/r/#/c/19389/

answer your question?
Please suggest improvements and improve the text as you notice gaps.

Best regards,
Ole

This is a known issue with how the retry mechanic interacts (badly) with gerrit 
occasionally.  This odds of this happening were a bit higher over the last
couple of days specific to centos retries.   This is tied to the JNLP changes
made to csit and how the initial connection is made.   While the change
has improved JNLP issues across the board there are a couple new nits
that ill have to debug.

At this point though I’m not going to touch/debug further until the csit 
jobs/reports are completed.

Im actually hopeful that ill be able to reduce the number of retries (or 
possibly completely) in the long run with the HAProxy bypass in place.

[vpp-dev] git commit template

2019-05-07 Thread Ole Troan

Hi,

I just uploaded:

 https://gerrit.fd.io/r/19391 make: git commit template  

The proposal is to use a new git commit template that tags commits with a type.
Which can be one of feature, docs, make etc.

The problem this is trying to solve, is how to programmatically figure out what 
features VPP supports.
By marking a commit, that report can (hopefully) be genereated automatically.

Please review and comment.

Best regards,
Ole-=-=-=-=-=-=-=-=-=-=-=-

I put some comments to this commint, but generally, my preference is that we 
don’t abuse subject line with xmass tree decorations.
Can we do something like:

Subject: : brief description

detailed description if any...

Hi Hongjun,

I have tested the HQoS Plugin with iperf3. Below is a simple topology I have 
implemented:
[cid:image001.png@01D5010B.5C565F10]

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 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?

[vpp-dev] VPP Load Balancer with active-standby

2019-05-07 Thread Yusuke Tatsumi

Hi all,

We've already used VPP LB plugin as active-active L3DSR load balancer, and It 
works well in our environment.
In addition to the above, I'm now interested in supporting active-standby load 
balancer for some particular cases, mysql for example which support only single 
active node.
So I plan to enhance LB feature to support active-standby.
In consideration of robustness of feature, adding member-selection-weight 
function is suitable I think.
With this method, VPP will do as follows,
- no weight setting (default): active-active
- weighted setting (ex. 6:4): active-active with 6:4 weighted
- weighted setting (ex. 10:0): active-standby
Do you have any option or much good idea?

Regards,
