Hi Florin, We are trying to achieve the mechanism, something similar to TAP interface, in VPP.
So, the packets coming out of the TAP interface, will be directed directly to the application. The application will receive the packets, coming via TAP interface, process them and send it down via the Host stack. Possible options, we could think of are:- - Enhance the session layer to provide a L2 transport mechanism and add nodes like tap-input and tap-out which would achieve the same. - Use the existing session layer by doing a IP/UDP encap and send it to the APP, via session layer and use existing mechanism. This introduces an overhead of additional encap/decap. We wanted to check if there is any alternate option to directly transfer the packets from the plugin to the VPP App, without even involving the session layer and have no additional overhead encap/decap, Please let us know your comments on the same.

I meant host stack is session apis. Is there any method to send the data to internal apps?

You want to deliver data to internal applications (supposedly using the session layer) without going through nodes like ip-local? If not, what do you mean by “sending through host stack”?
