Developed by ENST's multimedia services and networking department, the ROHC mechanism is capable of up to 95 percent compression of IP headers and 50 percent of packet compression, freeing up bandwidth and improving the efficiency of radio links for better quality voice, audio and video transmissions over IP.
ROHC brings tremendous advantages for network environments where bandwidth is limited or costly, as is the case for cellular or satellite links.
In the course of a joint project sponsored by the European Space Agency, we had the opportunity of experiencing first-hand the benefits of ROHC which made the satellite link more reliable while reducing the cost of transmission.
During recent meetings with operators in Europe it has become evident that demand for ROHC will increase during 2003.
Effnet ROHC is a software implementation based on IETF RFC 3095, delivered as an ANSI C language reference implementation, which runs on Sparc (Solaris), x86 (Linux, Windows, FreeBSD), and ARM7 but can easily be ported to other platforms.
Ericsson (NASDAQ:ERICY) has closed the circle from the initial idea to verification by hosting a successful Robust Header Compression, ROHC, interoperability test recently in Sweden.
ROHC means performance gains of typically 50 percent for IP based services in all 3G systems.
Robust header compression, ROHC, will be used in all 3G cellular systems (WCDMA, EDGE and, CDMA2000), substantially improving spectrum efficiency and service quality for IP services such as voice or video in Mobile Internet.
ROHC has been included in 3GPP specifications and is a new Internet Engineering Task Force (IETF) proposed standard, developed to increase efficiency over wireless links by compressing IP headers.
