p2p

I'm working on writing a Python client for Direct Connect P2P networks. Essentially, it works by connecting to a central server, and responding to other users who are searching for files. Occasionally, another client will ask us to connect to them, and they might begin downloading a file from us. This is a direct connection to the other client, and doesn't go through the central server. What is the best way to handle these connections to other clients? I'm currently using one Twisted reactor to connect to the server, but is it better have multiple reactors, one per client, with each one

I am currently experimenting with WiFi-Direct (WiFiP2p) for a project I'm working on and wanted to know if one can create bridge between groups, thus joining them together? Based upon the white paper released by the WiFi Alliance, it should be possible (though "The P2P Specification does not describe the mechanism for this capability – implementation is specific to the vendor"). I have looked through the internet and have found some answers ( this , this , etc.) but I feel that none are particularly conclusive. Looking at Andoid's API hasn't helped much either. The scenario I'm trying to

My knowledge about network programming is limited, so, all the comments are more than welcome. Essentially my question boils down to the following question: Q1. Is there really such a thing as decentralized asynchronous cross-platform peer-to-peer communication ? Let me explain myself. If we have two http servers running on computers with actual IP addresses, then clearly the answer is yes, assuming one writes a protocol for the interaction. To go one step further, if one of them (or both) is (are) behind a router, then, with port forwarding the communication can still be established. However,

I am looking for a way to transmit data when two phones are close by. This needs to be cross platform so I cannot use NFC or iBeacon. I plan on using allJoyn to send information. I would only like to send data to others that are within a few feet of me. Is there any way that I could get an accurate reading of distance on other phones? Or can I get an accurate distance on a master device that could be placed in the room? Shot in the dark answer: If both devices are on the same wireless WiFi network (same subnet), then any devices on same network are "close enough". When on the celluar network

I'm start to develop/prototype a Peer-to-Peer video chat application for iOS and Android. I'm trying to create a similar experience to FaceTime or Tango -- ie good quality video, works across the internet/3G (not just on the same LAN). I'm just getting started in the research phase. I've done a bunch of Googling, but haven't found much (since this is a new area for me, I'm probably looking in the wrong places). Can you suggest any pit falls that I should expect to run into? What protocols should I use (from the reading I've done it looks like people use SIP or XMPP, are these the best options?

How does one PC connect to another over the internet to another PC? An example would be a program listening for connections on PC 1. PC 1 sits behind Router 1. PC 2 has a client program trying to connect to PC 1. What is the correct technology/technique to use as the listening program in this situation? This article by Brian Ford explains how peer to peer communication across NATs work. Most routers also expose a Universal Plug and Play interface (uPnP) which can be used for port forwarding and NAT traversal. You should also check out the STUNT library which is an easy to use NAT traversal

G'Day programmers...I am planning to make an application which will be using peer to peer bluetooth connection between two different iOS device. So my question is, is there any good tutorials which can guide me through? Purpose is to send a stream of strings, like in chat application. I want to learn so you may give me a direction something like, "Hey check this, XYZ API they intent to do what you are looking for..." Or "There is a tutorial ..." Thank you for any kind of help! Research So far : Below link is about networking through wifi but not bluetooth http://jens.mooseyard.com/2009/05/a
