> In the above what does stream_instance_id does? In CTF documentation [1] it looks like packet.header can contain three values(magic, uuid, stream_id) then what is stream_instance_id?<br>
<br>
This is the ID of the stream itself, whereas `stream_id` is in fact the<br>
ID of the class or type of stream. Many streams (one per CPU, for<br>
example) can share the same stream class ID (`stream_id`), but have<br>
different stream IDs (`stream_instance_id`).</blockquote><div> </div><div>Okay. This was very helpful.

Was that turnaround time good enough for you?<br></blockquote><div>Thanks for helping me out. I am GSoC 2019 student at RTEMS.
