The Research Of Otn Technology Applied To The International Business Transferplatform Of The China Unicom

With the IP network and the bearing of the trend of development, the traditional flat is gradually to the transmission network bearing layer infiltration. This requires the next generation of transmission network must also have the advantage of bearing nets and transmission network. In order to meet the characteristics, must develop new technology to make up for the deficiency of the transmission network. For instance, the use of OTN technology or all optical technology to provide large particles bandwidth crossover and large capacity of bandwidth, high-speed long distance transmission, with PTN technology to provide has the characteristics of the multiplexing bandwidth security, grouping, transmitted, at the same time provide OAM and protection, the last, by using intelligent network technology to control the link of a flexible. In the existing MSTP equipment and WDM, based on the seismic equipment business advantages in data OTN technology will become the next generation of transmission network, the evolution of direction. In this paper, the international Internet penetration in the construction business platform introducing OTN technology were discussed and studied. Specific content including some aspects:(1) to introduce unicom business development trend and international Internet penetration business platform construction background. At the same time, according to the needs of the business, in the analysis of the present situation of the network based on the summary of the limitation of network, and the development trend. Meanwhile, discussions on the existing transmission network OTN introduced the advantage of technology.(2) OTN technology of this system structure, key technology, combined with the application of the technology at home and abroad ASON case, analyzes the feasibility of the technology OTN introduced.(3) In Beijing unicom present situation and the technical characteristics OTN transmission network, from the needs of the business, network structure, professional design, equipment selection, bearing network protection specific analysis, design the network routing demand solutions. According to the risk analysis, network ASON structure, control plane requirements, protect recovery plan, the inter-communication, etc, this paper give specific research in our country’s construction ASON of network transmission network solutions.(4) Introduced this OTN technology needs to pay attention to OTN problems, and the development trends are also prospected.Through the analysis and research, and prove the transmission network in Beijing and the development based on the introduction of the new transmission network OTN technology is feasible, is necessary. Overall, introduced in OTN, duty to stage introduced gradually OTN interface support function, OTN networking and protection function, the OTN intelligent function. The OTN or OTN+PON combination of transmission is a good choice, it will enhance the access layer (bandwidth resources manageability and operation ability, and the transfer of data services to provide more efficient transmission network solutions.
