P2P is leveraging the computing, storage, and network resources on the edge of the network. P2P causes us to rethink our assumptions about connectivity, collaboration, and network infrastructure. What started out as simple file sharing has grown to include a wide array of applications and services:
Future Internet platforms and desktop applications will resemble P2P systems such as Jabber and Groove. In addition, corporate infrastructures might be extended to the global network using P2P distributed services. A fascinating view of this environment is already emerging. This chapter showed a variety of P2P applications and the architectural issues that needed to be resolved to build them. Many of these applications make use of the Java technologies introduced next in Chapter 4, "P2P As a Framework for Distributed Computing." |
