If you don't know about TCP, UDP hole punching, don't bid. If You have not done any P2P application then it is less likely you can not do it successfully.
I need a proof of concept or working code for TCP and UDP hole punching.
Here is the scenerio.
(1) I have a central server X with public IP address.
(2) 2 clients (A, B) connect with central server from two different countries with private IP address which are behind firewall or router.
(3) Central server will pass the public IP of AB, public IP of B to A.
(3) Server A will connect directly to Server B with the information it received from central server.
(4) A and B are connected and without any more help from they can communicate using TCP or UDP protocol.
(5) Able to send simple "hello message" and get a reply from other end.
Implements both protocol or at least TCP protocol.
Before any payment project should be successfully tested using clients which is behind firewall and located in different network.
Implementation should have two component.
(A) Central server component, where Client first connected. It should be able to get and pass the public address of connected client to any other connected client
(B) Client component: Code to connect to central server. Receive connection detail for other client from central server. Able to initiate or negotiate connection with other client to get connected and start communicating.
After establish communication using UDP and TCP successfully you can extend to add voice functionality using G729 or Speex codec. (P2P, client to client) using UDP protocol.
with voice budget upto 400$, without voice upto 200$.
Any of the following language is acceptable in order.
C#
VB
C/C++
Java
