A method for on-demand telemetry path planning for mega constellation satellite networks

This invention discloses an on-demand telemetry path planning method for mega-constellation satellite networks. First, an on-demand telemetry mechanism is established based on a programmable data plane, realizing a logical shift from "blind telemetry across the entire network" to "precise target point perception." Second, a projection dimensionality reduction strategy is used to eliminate non-target nodes, significantly reducing the computational complexity in large-scale networks. Next, a Hamiltonian cycle structure is used to unify the start and end points of each telemetry path, ensuring that a single closed path only requires initiating a telemetry process once at the source node, significantly reducing system process maintenance overhead. Finally, based on the capacity limit of a single telemetry message, the initial global Hamiltonian cycle is truncated to obtain a multi-loop planning scheme that satisfies the telemetry message capacity constraint, completing the on-demand telemetry path planning and thus constructing an efficient and low-overhead telemetry path planning scheme.
