RADVISION NAT Traversal Toolkit is a STUN (Simple Traversal Underneath NAT) developer solution for STUN Clients and Servers that complies with IETF Standard RFC 3489 and the latest draft-ietf-behave-rfc3489bis-18.
The Toolkit enables support for both existing STUN servers, as well as those under development, and serves as a foundation for ICE (Interactive Connectivity Establishment), which is based on the updated STUN standard.
STUN NAT Traversal Toolkit Highlights
|The STUN NAT Traversal Toolkit is used to develop:
- NAT aware VoIP Clients
- STUN Servers
- ICE-ready network elements
The NAT Traversal Challenges
- Enables development of STUN clients and servers compliant with current STUN servers and ready for future generations of STUN, which are mandatory for ICE.
- for seamless integration with all RADVISION’s protocol stacks, including SIP, MEGACO, DIAMETER, RTSP, and RTP.
With the growing awareness of the advantages of voice and video telephony over the Internet, the need for viable standard-based solutions to traverse NAT are felt by enterprise and home users alike. NAT traversal solutions are necessary to allow transparent communication with anyone, anywhere in the world, while maintaining security and privacy.
The STUN protocol was developed to solve certain NAT shortcomings. While providing many benefits, NATs can break many existing IP applications, making it difficult to deploy new ones.
