NAT Traversal Technology

Eyeball has developed AnyFirewall Technology to ensure seamless traversal of media across different NATs, firewalls, UPnP gateways, & web proxies. This comprises of two products:

1. AnyFirewall Engine (AFE) - the industry's leading firewall and NAT traversal SDK offering the most comprehensive implementation of STUN, TURN and ICE.
    

2. AnyFirewall Server (AFS) - a carrier-grade STUN and TURN server ready for licensing and mass deployment.

Here are a few highlights about Eyeball’s NAT traversal solution:

• Developed using industry standard protocols: IETF standards of STUN RFC5389, TURN RFC5766, ICE RFC5245, ICE-TCP [07], nat-behaviour-discovery and UPNP.
   

• 100% call completion: In addition to implementing ICE for NAT/Firewall traversal, UPnP and HTTP Proxy tunneling are provided to ensure 100% call completion.
   

• High peer-to-peer call completion rate: More than 95% of calls are completed peer-to-peer in UDP-enabled networks.
   

• Small SDK footprint: The standard footprint is less than 300kB, but smaller footprints are available for embedded devices and other environments where available memory is limited.
   

• Multiple platforms: AFE is available on Microsoft Windows, Linux, Android, iPhone/iOS, Neutrino, J2ME, and Windows 7, with other platform support available upon request.
   

• Easy to integrate: The AFE socket API is based on the standard Berkeley socket API, which is used in most operating systems. This allows AFE to be integrated quickly into existing products.
   

• Complete solution: TheSTUN TURN Server - AnyFirewall Server(a standards-based STUN/TURN relay server) and the AnyFirewall Engine (a standards-based ICE client) provide a complete solution for NAT traversal.
   

• Service scalability: A singleSTUN TURN Server - AnyFirewall Serversupports more than 10,000 concurrent calls at one time, with more calls supported by simply adding another server.
   

• Product maturity: Eyeball has been a leader in NAT traversal solutions for over 5 years. Our products are field tested by millions of end-users all over the world.

Sections ‎5.1 and 5.2 presents AnyFirewall Engine and Server solutions respectively and section ‎5.3 provides a typical call completion scenario using the solution.
