Hi All, 

 

In the Linux Suse 10.1 machine, the value of the IP-ID in the IPv4
header is always zero (i.e., constant) in the entire IP datagrams.

The IP-ID Encoding, as per RFC 3095, of the RTP profile doesn't handle
this case (constant IP-ID).

 

Also this issue had been discussed in the mailing list.

http://www1.ietf.org/mail-archive/web/rohc/current/msg01502.html

 

When I searched in the Internet, I found few proposed solutions (yet to
read them). 

            (draft-ietf-rohc-rfc3095bis-improvements-03.txt,
draft-kapoor-rohc-rtp-new-requirements-00.txt
<http://www.potaroo.net/ietf/idref/draft-kapoor-rohc-rtp-new-requirement
s/rfcmarkup?repository=/away/ietf&url=/away/ietf/all-ids/draft-kapoor-ro
hc-rtp-new-requirements-00.txt> , 

 RFC 3643 -- A Compression Profile for IP)

 

Please let me know the solution/standard that everyone is following for
this issue in the RTP Profile.

 

Thanks,

Gangadharan
