Re: [rfc 5225] question on reordering ratio

Hi Suneeta,

The reordering ratio will address the reordering between the compressor
and decompressor. Its more closely related to over-the-air ARQ
algorithms.

The parameter "reordering ratio" is dictated by the compressor to give
some indication about its perception about the reordering channel as
seen by the decompressor. So you can see that its located in a number of
context control packets (co_common). 

Thanks & Regards
Biplab
