基于国干网MSTP网络传输4K超高清信号的仿真测试

Simulation Testing of 4K UHD Signal Transmission Based on MSTP Network of National Backbone Network

本文首先提出了国干网业务传输形式升级的必要性,而后对4K(UHD)超高清信号、MSTP网络的理论进行了简要介绍。结合现有业务及网络情况,开展了基于国干网MSTP网络传输4K超高清信号的探索与仿真测试,测试结果将为国干网未来发展4K超高清等业务提供一定依据和实践参考。

This paper first puts forword the necessity of upgrading service transmission form of national trunk network,then briefly introduces 4K(UHD)signal and MSTP network theory.Combined with existing business and network situation,the paper carries out exploration and simulation test of transmitting 4K UHD signal based on MSTP network.Test results will provide certain basis and practical reference for 4K ultra-high-definition development and other services by national backbone network in the future.
