Multi-path data distribution system and multi-path data distribution method

The invention discloses a multi-path data distribution system and a multi-path data distribution method. The distribution system comprises: a keep-alive detection module used for detecting all paths connected with second-level analysis servers by using a keep-alive packet generated by a first-level device, generating keep-alive target path information and sending a keep-alive detection packet to atarget path; a keep-alive analysis module used for analyzing a keep-alive response packet returned by a second-level server and received by the first-level device, wherein the analysis contents comprise a function module for extracting relevant path information for analyzing and maintaining a reachable path state; and a traffic distribution module used for performing homologous and homoclinic load balancing distribution on the traffic in the path after the first-level device determines the keep-alive reachable path. By adoption of the scheme, all connection paths can be detected, the reachable path is maintained, and
