RObust Header Compression (ROHC): A Profile for TCP/IP (ROHC-TCP)
Reviewer: Joel M. Halpern
Review Date: 16-July-2012
IETF LC End Date: Past
IESG Telechat date: 19-July-2012
Summary: This document is ready for publication as a Proposed Standard.
(I am guessing that I am confused about the major issue below.)
Major issues:
In section 5.2.2.2 on negative acknowledgments the text says that
the compress must ... "unless it has confidence that information sent
after the packet being acknowledged already provides a suitable response
..." In the abstract, the sounds great. If you know that you have
solved the problem, don't worry about it. But since this is the
specific response to the NACK, it is very unclear what would constitute
"confidence". (Other places that refer to gaining confidence provide
specific descriptions of how it is gained. The primary methods for
gaining confidence are receiving acks or sufficient transmissions. If
all that is meant here is sufficient transmissions, then saying that
would be helpful.)
Minor issues:
It seems to me that the labeling of entire sections as Informative
or Normative is not particularly helpful. It is unlikely to confuse
anyone, so I don't see any harm in it either. It just seems odd.
