Abstract


Distributed Service Network (DSN) is available for the new generation of telecom services and mobile Internet business operators, and manageable distributed core network architecture. DSN core network based on P2P architecture, there is no central node is composed of a large number of peer-to-peer nodes. Compared with traditional centralized core network, DSN will need to manage a greater number of nodes, DSN is usually set up a self-organized manner, allowing nodes dynamically join and leave. In this case, the network management becomes more complex, but single-center structure of the traditional centralized network management system, not only a single point of failure-prone, and prone to a single point of performance bottleneck in the DSN, the distribution of network management type of imperative. The first DSN architecture, hierarchical model of distributed network management system. Distributed network management system is divided into three layers: center management, domain management, management. Center management prepared by the master management control node, is mainly responsible for a summary of the data and manage user access. The manage user can complete the required network management operations through management control node. Domain management by the of multiple management capacity nodes, all management nodes together constitute the P2P network. The management capacity nodes mainly responsible for the polling managed devices, the data reported and command issued. Through the introduction of P2P technology in the domain management, NMS network management functions load balanced distributed to multiple management capacity nodes, each managed device access to the network service management capabilities node . When some node fails, the network management system can quickly automatic topology adjustment. By management through real-time monitoring agents deployed in the network element equipment. Layered network management structure proposed in this article, on the one hand, you can reduce the transmission of network data, eliminating bottlenecks, increasing overall system reliability and scalability, on the other hand is easier to manage user access. Finally, a series of tests to verify the functional completeness of the design and implementation of this article NMS also further evidence of the introduction of P2P technology can solve the traditional NMS facing massive node access, network congestion and single point of failure problems.
