[rohc] ROHC-v2

["Mallikarjuna.H.B" <mallikarjuna.boralingegowda at lntinfotech.com>]

Hi,
This message is in response to the rohc-v2 draft given below:
       draft-ietf-rohc-rfc3095bis-rohcv2-profiles-01

outer headers and the ipv6  extension headers are to be sent to the decompressor through the IR packet as the static and the dynamic chains and in the CO_repair packet as the irregular chain.
After studying RFC 4996, it is written that irregular chain to be defined analagous to the static chain.i am not understanding what is the meaning of it?
if anybody asks me i shall say that the irregular chain is not clearly defined.any body who knew this please plz reply to this.i am eagerly waiting to know how the irregular chain is defined.


for eg, say to compress packets with 2 ip ext headers. Initially i shall send these headers through the IR packet. later if the second header changes and that needs to sent through the irregular chain. even if i send the 2nd header how the decompressor could know?


if the outer ip also present what should be the order of sending these headers in the irregular chain.


regards,
Mallikarjuna
