Software Defined Network based 5G and Time- Sensitive Network Fusion For Power services with Ultra-low Latency Requirements

The power system has some services that are sensitive to packet loss and delay, such as distribution automation, distribution network differential protection, and intelligent distribution. Even a small increase in response time will affect service performance. With the development and construction of 5G network system technology, the network demand of vertical industries is upgraded to high-performance indicators such as ultra-reliable and low latency communications, and certainty. The integrated deployment of time-sensitive network technology and 5G network system has become a research hotspot. With the help of time-sensitive network (TSN) technology, 5G network can provide defined transmission guarantee capability for power service and meet the ultra-low delay requirements of power service. This paper aims to use software defined network (SDN) to achieve the integration of 5G and TSN, so as to better meet the security, reliability, flexibility requirements of power service, improve differentiated service guarantee ability, and greatly improve the independent and controllable ability of power enterprises for their own service.
