Monitoring Mechanism Of P2p Applications In The Computing Platform

P2P is new model which carries distributed process on Internet. This kind of technique makes most use of the idle resources of Internet to attain the biggest resources sharing and integrated service. Now enterprise information system with the P2P as the basis has been carried on. However because of complete dispersion of P2P there are so much wasting-time and unpractical operation used to create and close connection. And these operations make system capability descend. The next in order, in P2P network each peer can get the service and provide the service at the same time. We can guarantee capability and quality of these services by the control on the central peer in traditional calculation mode. However in P2P each peer is equal quality and capability can't be guaranteed. To lots of enterprises key business application depend on system capability greatly so capability descent usually results in the huge loss. So capability insurance is the most important in new kind of business enterprise information system. Facing these problems a series of theories is needed to supervise the whole system and handle the imaginable problem in time and exactly.A bran-new capability insurance mechanism on JXTA with four tiers is put forward on this text according to six basal protocol of JXTA. The interface tier provides the system monitors with an unitive interface to operate the software. The logic ties includes logic construction. According to different function request different peer groups and EJB/ JavaBean should be set up. The data tier: the database keeps two kinds of data: one is used as the standard to value the capability and it is input by operator. The other supervising history data saving as various kinds of form: planar data, charts and report forms. JXTA P2P virtual tier is a virtual network made up of peers. It provides a safe mechanism to guarantees the basic safety.Then how to institute appropriate strategy depending on system situation and alarm distinctly with different extent problems are discussed on this text laterNow the business application about P2P is popular in the enterprise. 4-tier capability insurance mechanism mentioned on this text provides academic function and shows a safety, easy going and steady solution.
