Performance Test of Power Service Based on Slicing Packet Network

With the development of large-bandwidth and IP-based bearer services in the power communication network, the existing SDH+PTN transmission system has been unable to meet the business development requirements during the “14th Five-Year Plan” period. SPN technology has evolved from PTN technology, which not only can provide ultra-large bandwidth, but also has highly reliable hard isolation (FlexE), which can carry low-delay scheduling data networks and other control services in areas I and II, as well as Carrying large-bandwidth data communication networks and other management services in areas III and IV. This paper proposes a test plan for the SPN analog networking, and tests the service isolation capability, transmission delay, and hybrid networking capabilities of the SPN networking. The analysis and comparison of the test results can provide support for the introduction of SPN technology by Shandong Electric Power during the “Fourteenth Five-Year Plan” period, and at the same time lay the foundation for the development of the transmission system of the electric power communication network.
