RTP / UDP / IP Header Compression
نویسنده
چکیده
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), European Technical Standards Institute (ETSI), etc. This document covers only lower layer guidelines for compression of RTP/UDP/IP and UDP/IP headers as specified in [RFC3095]. Both general guidelines and guidelines specific for cellular systems are discussed in this document.

RObust 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...
متن کاملPerformance of RTP/UDP/IP header compression in cellular networks
A number of real-time multimedia services are being designed to operate over mobile end-to-end IP networks. Such services require the use of the Real Time Transport protocol (RTP) in order to provide acceptable Quality of Service at the receiver. The resulting RTP/UDP/IP headers however constitute a significant overhead, particularly at low-bitrate speech applications. This paper examines curre...
متن کاملRFC 4247 Requirements for Header Compression over MPLS
Voice over IP (VoIP) typically uses the encapsulation voice/RTP/UDP/IP. When MPLS labels are added, this becomes voice/RTP/UDP/IP/MPLS-labels. For an MPLS VPN, the packet header is typically 48 bytes, while the voice payload is often no more than 30 bytes, for example. Header compression can significantly reduce the overhead through various compression mechanisms, such as enhanced compressed RT...
متن کاملEffects of Interleaving on RTP Header Compression
We discuss the use of interleaving as a bandwidth efficient means of protecting audio streams from the effects of packet loss in the Internet. The adverse effects of interleaving on IP/UDP/RTP header compression are noted and a number of schemes which remedy this problem are discussed. Keywords— RTP, Interleaving, Voice-over-IP, header compression.
متن کاملRFC 5225 ROHCv 2 Profiles April
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...
