Dear tacker project members,

Hello. I am Hosung Baek and Ph.D.student at Korea Univ.

I am interested in the VNFFG feature in Tacker project, and I want to
develop the "Redundancy VNFFG module" in tacker.

As far as I know. it is difficult to apply the VNFFG configuration where
there is low loss requirement such as DetNet and URLLC.

Because there is no module for reliable VNFFG.

The module to be developed is described as follows.

It is a function to construct a disjoint VNFFG by adding redundancy VNFFG
module to the tacker VNFFG feature and to transmit the data to two disjoint

To implement this module, two VNFFGs must be configured for one network
service and the function to remove redundant packets in two different paths
is required.

I want to develop this module and contribute this to tacker project.

So could you tell me the contribution process in OpenStack tacker project
if possible?

Yours sincerely,

Hosung Baek.
