The Optimization And Test Analysis On ASON Transmission Network

With the development of communication technology, voice, data and multimedia services in the rapid growth of network bandwidth, the interface and operation put forward higher request, request for transmission network can provide more flexible network exchange and efficient protection and recovery capability. Automatic switched optical network concept is adapted to transmit network development and put forward, for a change of transmission of optical network.This paper discusses the key technology of ASON, business level and so on, combined with ASON network can be based on customer needs at different levels, with different grade of service business of this advantage, in accordance with the Shandong Unicom related standard, through building a 2 fiber 10G multiplex section shared protection ring, to test the ASON mesh network and traditional SDH ring network collaborative work, as well as the test ASON equipment and its control and management level of SDH loop network structure compatibility. In ASON mesh network (also known as MESH), all the nodes and all nodes in the topological connection and form a mesh structure. The project will be ASON experimental network construction in provincial level line, consciously in the design of the network has a variety of types of service access ability and multiple service access interface, and the key of ASON multiple protection and restoration ability resource automatic discovery, topology and traffic engineering and other aspects of the test. The configuration of the test, the DCN data communication network, interface testing, equipment hardware and a series of experimental test.Through the test result that MESH network can withstand high amounts to 6 network, network security is greatly higher than that of traditional ring network; the network mode can realize the direct route, the effective use of resources; each node, link together, automatic, intelligent realization of whole network resources sharing, so as to enhance the utilization rate of network resource.
