Digital Organisms Auxiliary Node

Because of fast development of Internet and computer technologies。But the server performance and network bandwidth backbone bottles existence。Led to the traditional client / server (C / S) model of network applications has been greatly constrained, can not meet the increasingly demanding needs of users。P2P system is the current research focus is the large-scale network applications。And the traditional C / S patterns are different, P2P systems, each node is both a client may also be a server, so each node can provide services outside。To a large number of distributed nodes in the system to find a resource, not an easy thing。Now some of the P2P system uses super-node approach to management of resources。In essence, in a certain region, according to certain rules one or more of the nodes selected to manage the computer nodes in the region of resource information, address information。Teaching and research in distributed parallel systems for many years based on the research and development, combined with the characteristics of P2P application mode to develop a system of digital organisms。At present, the Digital Organism System has been achieved and development of an organism of traditional P2P system, the main function of resource management。If the super-node in that time period, the node does not receive regular heartbeat messages. Then the super-node that the ordinary node failures。The inadequacies of the system lies in the time scale, super-nodes to handle large amounts of information, easily become the bottleneck of the system。This paper designs and implements a class for the service of information resources, support management system. It is through a three layered logical structure, the service source node organized into dynamic adaptive zone, from each district within select one or more managed nodes, is responsible for other customers within the area managed nodes, these nodes are Digital organisms auxiliary node。Been tested: digital organism auxiliary node system designed to meet the functional requirements, be able to a certain extent to decrease server load and improve system usage.
