It is possible. I see at least 2 parts to your question. (It is not going to be HTTP packet. It is a lot more complex than that.) First off, I believe you might be talking about a concept called decentralized P2P network. The main idea behind a decentralized peer-to-peer network is the fact that … Read more
You should try libtorrent (rasterbar). http://libtorrent.org If you want to write your client in python, on linux, install it with: sudo apt-get install python-libtorrent A very simple example of python code to use it to download a torrent: import libtorrent as lt import time import sys ses = lt.session({‘listen_interfaces’: ‘0.0.0.0:6881’}) info = lt.torrent_info(sys.argv[1]) h = … Read more
I wouldn’t say that something uses a wire-level protocol or doesn’t – I’d talk about which wire-level protocol it uses. Basically, if something’s communicating with a remote machine (even conceptually) then there’s some data going across the network connection (the wire). The description of that data is the “wire-level protocol”. Even within that, you would … Read more
I know google just came out with a cross platform api for ios and android devices to communicate with each other. I don’t know what you’re exactly looking for but this one lets you pass small binary payloads between Android and IOS devices. they don’t have to be on the same network at all either … Read more
P2P connectivity in a nutshell. Assume we’re talking about UDP here. The steps below can also be applied to TCP with some adjustments. Enumerate all your local IP addresses (usually only 1). Create a UDP socket on a given port number** for each adapter with an IP address. For each socket created in step 1, … Read more
This is what Freenet basically is, Freenet is free software which lets you publish and obtain information on the Internet without fear of censorship. To achieve this freedom, the network is entirely decentralized and publishers and consumers of information are anonymous. Without anonymity there can never be true freedom of speech, and without decentralization the … Read more
Try enabling these services on the server: Peer Name Resolution Server (Install through Server Management) Peer Discovery Server (Install through Server Management) Simple Service Discovery Protocol Service (SSDP Service) Then simply ensure that the Firewall Rules are modified; by default they block IPv4 / IPv6 Teredo Tunneling driver. IPv6 needs to be supported as it … Read more
Another interesting question that arises is of BitTorrent because they can work on any device and even behind a NAT. I am not able to get any explanation of how BitTorrent works. This statement looks like you assume that bittorrent needs full connectivity to operate. That is incorrect. Behind a NAT device you will still … Read more
No Already answered here for more details: Do websockets allow for p2p (browser to browser) communication? Update: The WebRTC protocol and API is making rapid progress and allows a Data Channel to be established between two peers (you still may need a STUN/TURN server for the initial NAT traversal and setup).
There’s no way around having to know at least one initial peer to discover more. Fully P2P protocols, such as Gnutella or Gnutella2, or the simpler Overnet (made famous by Storm Worm), are based on each client having a start-up list of a few peers. These can come off a web-based automated tracker for example. … Read more
