Learning Network Programming with Java

Applications-based P2P networks

There are many applications that are based on a P2P network. They can be used for the following:

• Content distribution: This is file sharing (files, music, videos, images)
• Distributed computing: This is when a problem is divided into smaller tasks and executed in a parallel fashion
• Collaboration: This is when users work together to solve a common problem
• Platforms: These are systems on which P2P applications are built, such as JXTA, and Pastry

Distributed computing leverages the power of larger numbers of smaller computers to perform a task. The problems amenable to this approach require that they be broken down into smaller units and then executed concurrently on multiple machines. The results of these smaller tasks ...
