The packet you receive, what do you do with it? If you don’t forward it, you have two choices:
* You could deallocate its buffer. * Or, better, recycle it and use that packets buffer for your outgoing packet. That way you avoid the expense of allocating a new one. Chris.

The application is running fine, but when I send some thousands of packets, at some point vpp starts to give "buffer allocation failure" error. Where do you think could be the problem. Is the node not correctly de-allocating the buffer or there is some specific vpp and/or system configuration that can cause this problem? Best regards, Alessio
