[RoHCv1.2.0] RoHC Ext-03 Encoder & Decoder

Asked by Orville Andrade on 2009-10-23

Hi All,

I find in RoHCv1.2.0 while 'packing or unpacking' the 'IP-ID' field in the Ext-03 header the absolute value of 'IP-ID' is being used and not compressed 'IP-ID' bits (using Offset IP-ID encoding) as specified in Section 5.7 (beginning) of RFC3095.

Is this understanding correct??

Hi !

Not sure of what is really specified in the RFC. The ext3 extension format described in the §5.7 describes a 2 bytes long field for the IP-ID, and thus I understand that this field is not compressed. However, the RFC refers to the beginning of the section where IP-ID coding is described...

Someone expressed the same opinion in bug #761955. I finally take some time on the problem. This is now confirmed: the library was not RFC-compliant on that specific point. Correction is in progress.

Can you help with this problem?
