<br>
I hope this is the correct mailing list for my questions, otherwise <br>
please excuse me and let me know where my questions should be posted.<br>
<br>
I was looking for a data structure capable to manage O-RAN Fronthaul <br>
CUS-U headers (attached a screenshot of the header structure form a <br>
packet analyzed with Wireshark)<br>
but I couldn't find one.<br>
<br>
I would like to be capable to identify the different port ids but also <br>
the number of PRBs in the section part.<br>
<br>
I wrote my own implementation for a simple use case (I don't take in <br>
consideration different versions and or data directions)<br>
but it's enough for me at the moment.<br>
<br>
What I wanted to ask is the following:<br>
- Does a data structure for this kind of header already exists?<br>
- If it doesn't exists is it planned?<br>
- If it's not planned could it be of some interest?<br>
<br>
If there is interest I would be happy to share what I developed up to <br>
now to receive comments and/or assistance on how to make it fully <br>
functioning.<br>
<br>
Best regards,<br>
Mattia<br>
