STOCKHOLM, Sweden, Jan. 14, 2002 (PRIMEZONE) -- Effnet, a leading developer of Internet Protocol (IP) header compression technologies, announced the release of its new Effnet CRTP(tm) software today. The software, ready to begin shipping this quarter, reduces bandwidth requirements for wireline Voice-over-IP (VoIP) by as much as 60% for IPv4, and 75% for IPv6 networks. Media gateways, routers, firewalls, modems and customer premise equipment can deliver significant bandwidth savings by incorporating EffnetEdge(tm) Header Compression technology into their products. These savings can translate to more VoIP channels and improved voice quality at a given bandwidth. This is especially important for Wide Area Network (WAN) access links, where bandwidth consumption is most critical.
In VoIP applications such as IP Telephony and audio and video conferencing, IP transmissions frequently wrap 40-byte packet headers around 15-35 bytes data payloads, creating a massive "header overhead" for VoIP applications. Effnet CRTP implements the Internet Engineering Task Force (IETF) RFC 2508, an industry standard developed to minimize header overhead for Real-time Transport Protocol (RTP) packets used for interactive multimedia applications on wired links. IETF 2508 header compression, also known by the acronym CRTP, is currently incorporated into a large installed base of VoIP-capable access equipment in both ISPs and enterprises. The addition of this technology to customer premise equipment and enterprise media gateways will significantly reduce the VoIP bandwidth costs over last-mile Internet access infrastructure, increasing the available VoIP channel capacity of a WAN access link by as much as 250%.
By using Effnet CRTP, the size of IPv4 IP/UDP/RTP headers are reduced from 40 bytes to as few as 2 bytes, leaving the packet's data payload unchanged. Header compression can be used effectively in conjunction with other bandwidth minimizing technologies, like voice compression and voice activity detection.
"Companies that develop VoIP equipment and software have a need for an efficient implementation of the CRTP header compression protocols," says Orjan Grinndal, Effnet CEO. "Now for the first time VoIP equipment manufacturers can purchase a product that enables them to compress the headers of these packets which delivers better performance and higher voice quality."
Founded by technologists who play a leading role in the IETF header compression working groups, Effnet is the first company to offer a complete line of header compression products with an integrated, comprehensive test and validation environment: HC-Sim. HC-Sim facilitates integration of Effnet's header compression software into the customer's target architecture. The validation functions allow designers to exercise their header compression implementation with numerous test cases that represent statistically common channel conditions.
