RFC 4362 A Link - Layer Assisted ROHC RTP
نویسندگان
چکیده
This document defines a ROHC (Robust Header Compression) profile for compression of IP/UDP/RTP (Internet Protocol/User Datagram Protocol/Real-Time Transport Protocol) packets, utilizing functionality provided by the lower layers to increase compression efficiency by completely eliminating the header for most packets during optimal operation. The profile is built as an extension to the ROHC RTP profile. It defines additional mechanisms needed in ROHC, states requirements on the assisting layer to guarantee transparency, and specifies general logic for compression and decompression related to the usage of the header-free packet format. This document is a replacement for RFC 3242, which it obsoletes.

Zero-byte Support for Bidirectional Reliable Mode (R-mode) in Extended Link-Layer Assisted RObust Header Compression (ROHC) Profile
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 ...

RFC 3095 defines the RObust Header Compression (ROHC) framework and profiles for IP (Internet Protocol), UDP (User Datagram Protocol), RTP (Real-Time Transport Protocol), and ESP (Encapsulating Security Payload). Some parts of the specification are unclear or contain errors that may lead to misinterpretations that may impair interoperability between different implementations. This document prov...

This document describes lower layer guidelines for robust header compression (ROHC) and the requirements ROHC puts on lower layers. The purpose of this document is to support the incorporation of robust header compression algorithms, as specified in the ROHC working group, into different systems such as those specified by Third Generation Partnership Project (3GPP), 3GPP Project 2 (3GPP2), Euro...
متن کاملRObust Header Compression (ROHC): A Compression Profile for IP
The original RObust Header Compression (ROHC) RFC (RFC 3095) defines a framework for header compression, along with compression protocols (profiles) for IP/UDP/RTP, IP/ESP (Encapsulating Security Payload), IP/UDP, and also a profile for uncompressed packet streams. However, no profile was defined for compression of IP only, which has been identified as a missing piece in RFC 3095. This document...

This document specifies ROHC (Robust Header Compression) profiles that efficiently compress RTP/UDP/IP (Real-Time Transport Protocol, User Datagram Protocol, Internet Protocol), RTP/UDP-Lite/IP (User Datagram Protocol Lite), UDP/IP, UDP-Lite/IP, IP and ESP/IP (Encapsulating Security Payload) headers. This specification defines a second version of the profiles found in RFC 3095, RFC 3843 and RFC...
