Abstract

The IRC protocol was developed over the last 4 years since it was

first implemented as a means for users on a BBS to chat amongst

themselves. Now it supports a world-wide network of servers and

clients, and is stringing to cope with growth. Over the past 2 years,

the average number of users connected to the main IRC network has

grown by a factor of 10.

The IRC protocol is a text-based protocol, with the simplest client

being any socket program capable of connecting to the server.
