Research on survivability of multi-layer electric power service

The terminal communication access network of power system is an information channel to guarantee the normal operation of the power grid, the rapid response of the fault, the efficient utilization of resources, the real-time transmission of the business and the sustainable production of electricity. For multi-layer networks, the use of single-layer survivability strategy may lead to the intensification of resource competition and the protection of the business, which requires the multi-layer network survivability strategy for inter-level coordination. In view of the current application status of multilayer communication bearer network, the survivability technology of multilayer network service carrier is researched, and the multi tier survivability network layer coordination is mainly studied.
