I would be able to do a comparative analysis of two methods as soon as I understand the mechanism described in draft-bormann-6lowpan-ghc. I have already spent a couple of hours trying to understand draft-bormann. At the moment, I cant figure out how the compression mechanism (Section 2) works and how was it applied to the examples listed in the draft. I suspect the draft does not have sufficient level of explanatory text at the moment.

Thanks
Mukul

How does this compare to draft-bormann-6lowpan-ghc?  It seems most of the gain will be from compressing out prefixes and zeros, which ghc should handle quite well.

The submitted draft specifies a compression mechanism for RPL control messages. We have currently specified compression formats for DIO messages and some of the options that sit inside a DIO. Future versions of this draft may include compression formats for other DIO options as well as other RPL control messages. The mechanism can even be extended to ICMPv6 messages in general.
