This document defines an additional mode of the link-layer assisted
RObust Header Compression (ROHC) profile, also known as the zero-byte
profile, beyond the two defined in RFC 3242.  Zero-byte header
compression exists in order to prevent the single-octet ROHC header
from pushing a packet voice stream into the next higher fixed packet
size for the radio.  It is usable in certain widely deployed older
air interfaces.  This document adds the zero-byte operation for ROHC
Bidirectional Reliable mode (R-mode) to the ones specified for
Unidirectional (U-mode) and Bidirectional Optimistic (O-mode) modes
of header compression in RFC 3242.

This document is a product of the Robust Header Compression Working
Group of the IETF.

This is now a Proposed Standard Protocol.

This document specifies an Internet standards track protocol for
the Internet community, and requests discussion and suggestions
for improvements.  Please refer to the current edition of the
"Internet Official Protocol Standards" (STD 1) for the
standardization state and status of this protocol.  Distribution
of this memo is unlimited.
