The World of Peer-to-Peer (P2P)/Networks and Protocols/IM

Instant Messaging Instant messaging can be considered a subtype of P2P, in simple terms it consists on the act of instantly communicating between two or more people over a network (LAN or WAN) mostly using text. This requires the use of a client program so that when a message is sent, where a notification is shown a short time after on the destination application, enabling it's user to reply to the original messages. IM protocols can be centralized or distributed or a mix of the two. Instant messaging allows users to send quick notes or reminders to other users in almost real time. IM can, but may not, include any P2P implementation or support extra P2P services like, file-sharing, VoIP or Video Conference the broad definition is that IM is the almost instantaneous trading of messages, whatever form it takes. Since any P2P network depends on participation, supporting some kind of IM implementations is very important as a way to create a community and sustain the network.
