Ensuring the safety and stability of the power communication system operation at low cost, as well as promoting the development of infrastructure construction, is the most important content in the field of power communication construction. Nowadays, with the increasing number of networks and related business models, the number of broadband users is growing year by year, and users have higher requirements for the efficiency of power communication system operation. Therefore, the backbone power communication business becomes more and more intensive. As OTN system can realize large-capacity transmission and crossover scheduling, it is regarded as the core layer in the power communication system.
Therefore, the integration of OTN technology with the backbone to form the "IP over OTN" carrying mode, resulting in the effective implementation of SNCP protection and similar SDH ring network protection frameworks, has promoted the significant improvement of the efficiency of backbone operation and the overall quality of power communication services.
While playing a role in the national backbone, the OTN optical transmission network also plays an important role in the metropolitan network. Broadband transmission services formed by the metropolitan aggregation router, metropolitan core router, and local network aggregation router at the core level of the metropolitan network can be completed through the application of OTN optical transmission network technology.
In the metropolitan network environment, the use of OTN optical transmission network can also access more types of broadband services on the basis of the original business volume, thus significantly improving the utilization rate of the broadband network. Moreover, the optical virtualization of the OTN system has great advantages, which can effectively enhance the safety and stability of the operation of the entire power communication system.
Due to the excellent transmission performance and "large-granularity" transmission performance of the OTN optical transmission network, it has been widely used by many institutions and organizations in society. With the increasing demand for "large-granularity" power scheduling in large enterprises and institutions, the OTN optical transmission network is playing an increasingly important role in large enterprises and institutions, and the application of the OTN system optical transmission network and other related technologies in practical power network systems can effectively improve the efficiency of network environment operation.
According to the analysis of many years of practice by communication companies, optimizing and integrating the circuit scheduling management of large enterprises and institutions with the OTN optical transmission network and applying it in practical circuit scheduling work can significantly improve the flexibility of "large-granularity" circuit scheduling. Since the cost of the OTN optical transmission network is low and there is no need to lay optical fiber cables repeatedly, the phenomenon of optical fiber resource consumption can be greatly reduced.
