This would allow for chats where anyone in the chat can act like a gateway by publicizing their IP address.

Cut out the server and set up chat entry so that log-in occurs by contacting an existing peer and downloading the active members from that peer.

Improve choking so that it's done on a tit-for-tat basis which would more efficiently distribute sent files across the chat.

Create a way to enable logging to record chats (especially long ones that roll off the top of the terminal and are lost permanently).

Then, the client sends out another round of KEEPALIVE messages to the list of peers. Any that haven't responded thrice are marked dead and removed from the chat. If it has been 20 seconds, the client cycles through the peers and checks if any of them haven't responded to the KEEPALIVE messages with an ALIVE message. Every time a client receives a message, it checks to see if 20 seconds have passed since the last round of KEEPALIVEs. The clients also track which of the peers are still in the group using KEEPALIVE messages. When the last piece of a message, written by, is received from, it is printed out in the format (). An unchoked peer can send a REQUEST, causing DATA to be returned (see ControlPacket.java). Peers express interest with INTERESTED packets, at which point they are either CHOKE'd or UNCHOKE'd, based on the available unchoke slots. Message/file data is broken into 5-byte 'pieces.' The piece is advertized with HAVE messages. The mechanism which distributes chat messages and files to all peers is modeled after the Bittorrent protocol. The path above can be either relative to current working directory, or absolute. Each line will be distributed to everyone else in the chat. Then start typing in the clients' standard inputs. username identifies a user when the other clients print out messages sent from this client.chat-name identifies which chat to join (can be any string but will determine which clients talk to each other).server-port is the port from the server command.server-ip is the IP address of the server (you can run a client on the same machine as the server using localhost).Then run any number of clients with the command java Client server-ip server-port chat-name username, with these arguments: Start by running a server with java Server port

InstallationĬreate documentation with make docs, which will place html documentation in the documentation directory. This reduces the number of copies the sender must deliver by distributing the load over the whole group.

It sends messages in a distributed manner, sending out each message in pieces and allowing recipients to download different pieces from other members of the chat. P2p-messenger is a groupchat application that allows users to message each other without having to talk to a central server after the initial connection occurs.
