Research on the 2M ASON technology in power communication network

Firstly, this paper analyzes the advantages of the traditional ASON technology in the network operation, and introduces a new 2M ASON technology to solve the problems of the traditional ASON application. Secondly, this paper explains the progressiveness of the 2M ASON from the network survivability and bandwidth utilization through the introduction of the principle of 2M ASON channel establishment, the anti-node failure technology, and the "demolition before reconstruction" channel recovery mechanism. Finally, this paper analyzes the properties of the production services in the power system, and proposes a scheme of the power differential protection service based on the characteristic of the 2M ASON.
