System and method for establishing peer to peer connections between PCS and smart phones using networks with obstacles
A method of circumventing network obstacles to provide a peer-to-peer communication channel between peers utilizing hypertext transfer protocol (HTTP) includes communicating a HTTP request from a peer device to a relay through a network including an obstacle where the HTTP request is intended for another peer device. The method further includes communicating a HTTP response from the relay to the peer device and establishing a communication channel between the peer device and the another peer device via the relay. The communication channel permits the peer device and the another peer device to send and receive data.
1. A method comprising:
receiving at a relay server an HTTP request from a first peer device via a network including an obstacle, wherein the HTTP request from the first peer device comprises data intended for a second peer device;
receiving at the relay server an HTTP request from the second peer device, the HTTP request from the second peer device including an indication that the second peer device is listening for connections;
generating at the relay server an HTTP response to the HTTP request received from the second peer device;
copying the data from the HTTP request from the first peer device intended for the second peer device into the HTTP response;
transmitting the HTTP response from the relay server to the second peer device; and
wherein the relay server does not buffer the data received from the first peer device intended for the second peer device.
2. The method of claim 1 , wherein the HTTP response comprises peer specific signaling.
3. The method of claim 1 , wherein at least one of the first peer device and the second peer device comprises software running on a mobile device.
4. The method of claim 1 , wherein the HTTP request received from the first peer device comprises configuration information.
5. The method of claim 1 , wherein at least one of the first peer device and the second peer device comprises a smart phone.
6. The method of claim 1 , wherein the obstacle comprises a firewall configured to restrict network traffic between the first peer device and other entities on the network.
7. The method of claim 1 , wherein the obstacle comprises a network address translation (NAT) server positioned on the network between the first peer device and the relay server.
8. The method of claim 1 , wherein the first peer device and the second peer device are protected by separate firewalls, and wherein the relay server is positioned on the network outside of both of the separate firewalls.
9. One or more computer-readable media, storing computer-executable instructions, that when executed by a computer, cause the computer to perform a method comprising:
receiving at a relay server an HTTP request from a first peer device via a network including an obstacle, wherein the HTTP request from the first peer device comprises data intended for a second peer device;
receiving at the relay server an HTTP request from the second peer device, the HTTP request from the second peer device including an indication that the second peer device is listening for connections;
generating at the relay server an HTTP response to the HTTP request received from the second peer device;
copying the data from the HTTP request from the first peer device intended for the second peer device into the HTTP response;
transmitting the HTTP response from the relay server to the second peer device; and
wherein the relay server does not buffer the data received from the first peer device intended for the second peer device.
10. The computer-readable media of claim 9 , wherein the obstacle comprises a firewall configured to restrict network traffic between the first peer device and other entities on the network.
11. The computer-readable media of claim 9 , wherein the obstacle comprises a network address translation (NAT) server positioned on the network between the first peer device and the relay server.
12. The computer-readable media of claim 9 , wherein at least one of the first peer device and the second peer device comprises a smart phone.
13. The computer-readable media of claim 9 , wherein the first peer device and the second peer device are protected by separate firewalls, and wherein the relay server is positioned on the network outside of both of the separate firewalls.
14. An apparatus comprising:
a processor controlling at least some operations of the apparatus;
a memory storing computer executable instructions that, when executed by the processor, cause the apparatus to perform:
receiving an HTTP request from a first peer device via a network including an obstacle, wherein the HTTP request from the first peer device comprises data intended for a second peer device;
receiving an HTTP request from the second peer device, the HTTP request from the second peer device including an indication that the second peer device is listening for connections;
generating an HTTP response to the HTTP request received from the second peer device;
copying the data from the HTTP request from the first peer device intended for the second peer device into the HTTP response;
transmitting the HTTP response to the second peer device; and
wherein the apparatus is configured to not buffer the data received from the first peer device intended for the second peer device.
15. The apparatus of claim 14 , wherein the obstacle comprises a firewall configured to restrict network traffic between the first peer device and other entities on the network.
16. The apparatus of claim 14 , wherein the obstacle comprises a network address translation (NAT) server positioned on the network between the first peer device and the apparatus.
17. The apparatus of claim 14 , wherein the first peer device and the second peer device are protected by separate firewalls, and wherein the apparatus is configured to operate on the network outside of both of the separate firewalls.
18. The apparatus of claim 14 , wherein the apparatus is part of a system that comprises the first peer device, the second peer device, and the obstacle.
