The essentials which are indispensable for a plug-and-paly environment used on networkingare presented. Then Jini technology is introduced and some of its limitations are pointed out. This paperextends Jini' s idea to be used in a plug-and-play system for Internet,which is known as I-Jini. The ar-chitecture of I-Jini and a mechanism for its catalog service location are discussed in detail.
Owing to the popularity of Napster and Guntella, the concept of P2P (Peer-to-Peer)is highlighted again.P2P is a mindset and the rethinking of the traditional network computing based on the client/server model. P2Pmeans to decentralize some aspects of a system, in order for the entities to exchange directly, which will explore theresources at the edge of network. The implication of P2P is expounded, and some typical P2P systems are listed.This paper also details the taxonomy of the architecture of P2P computing. Then, we delve into the application ofP2P in enterprise computing.
