[1] "Characterization and Measurement of TCP Traversal through NATs and Firewalls", S. Guha and P. Francis. IMC 2005. http://nutss.net/pub/imc05-tcpnat.pdf The key result of the paper is: TCP NAT Traversal can work 85%-90% of the time today (without any special assumptions on NATs), and 100% of the time between pairs of certain well-behaved NATs. See [1] for more details. An open-source Java library for TCP NAT Traversal is now available: binaries: http://nutss.net/stunt.jar source: http://nutss.net/jstunt_cvs.php documentation for library users: http://nutss.net/jstunt/doc documentation for library developers: http://nutss.net/jstunt/devdoc The above library has been tested for pair-wise connectivity across 11 brands of NATs from Windows and Linux hosts. NATs tested were Linksys, DLink, Netgear, Belkin, 3Com, Netopia, Allied Telesyn, SMC, Trendnet, USR. Out of the 121 possible pair-wise combinations, 113 connections are successful. The only ones that failed are when both the endpoints are behind the _same_ NAT that does not support TCP hairpin-behavior yet (see [1]). The java library is released under LGPL; contact me if this does not meet your needs. Feel free to extend it/port it etc. For P2P developers and users of the library -------------------------------------------- The JAR file above includes a sample echo-server/client program. The source code for the sample applications is at http://nutss.net/EchoServer.java and http://nutss.net/EchoClient.java respectively. To start the server, on a host behind a NAT, execute: java -cp stunt.jar EchoServer you@your.domain.com To connect to your echoserver from a client, execute: java -cp stunt.jar EchoClient you@your.domain.com (if you cannot run your own echo server, try pointing the client to the one I am running at echo@nutss.net) If everything goes well, you'll see something along the lines of: On Server: Accepted saikat930@ed.u.cs.cornell.edu On Client: Greetings saikat930@ed.u.cs.cornell.edu, this is the EchoServer at echo@nutss.net. Now you say something. On the client, you'll be able to type lines and have it be echoed by the server when you press enter. The library takes between 200ms to 1 second to connect, but slow DNS (sometimes due to the NAT) can increase the connection time by a bit. For people who want to develop the library further -------------------------------------------------- Anonymous CVS access is at: cvs -d :pserver:anonymous@gforge.cis.cornell.edu:/cvsroot/nutss checkout stunt_java The TCP hole-punching code and state machine are in the file STUNTCont.java. Extensive online documentation of all internal functions is provided. Things to do: - Wrap a java Sockets or Channels api around the existing API - Port to C, Python etc (may require writing a separate STUNT server) - Implement SIP backend for signaling messages (framework glue in place) - Implement some ICE-type negotiations for stacks of NATs - Integrate UDP hole-punching If you have any questions, comments, suggestions, or problems, do not hesitate to contact me. Cheers and have fun. -- Saikat _______________________________________________ midcom mailing list midcom@ietf.org https://www1.ietf.org/mailman/listinfo/midcom
