The Application Study About ASON In The Transmission Network Transition And Mergence

SDH transmission network is the based transmission technique currently, from the main technological development, the transmission network develop to three directions, namely intelligent, large capacity and high rate of professional ability. Facing the bandwidth consumption and dynamic characteristic growing with the broadband, video and 3G, the telecom competition environment is worsening, at the end, the segmentation of user,the continuously improveing reference of SLA,the serious safety and reliability problems brought by inevitable disconnection events, the traditional optical transmission network technology and annular seemed so hard.In this paper, eaplains the development tendency in the ASON technique, illustrates the technical advantage, characteristics and functions of ASON in the fixed-line and mobile network. Through the description of the reconstruction in local transmission network of Taiyuan unicom, passingly, explain the principle and the functional characteristics of ASON. Ultimately, expounds ASON technology playes a very important role in the communication network transformation and fusion.
