인터넷의 핵심 설계 철학 및 의사소통 systems, the end-to-end principle states that application-specific functions, like reliability and error checking, should reside in the end hosts of a network rather than in the intermediary nodes. The network itself should be kept simple, focusing only on delivering packets. This places intelligence at the edges and creates a ‘dumb’ network core. IRC follows the same spirit: servers relay text while clients add the features, so the best irc channels can be reached from almost any online irc client.
