The invention relates to the technical field of computer communication. In order to solve a problem that mobile scoring terminal equipment in sports competition causes a communication failure when a communication system is used for data transmission, the invention discloses a sports competition data communication and message distribution method based on positive feedback. The method mainly comprises the following steps: carrying out address planning of a transmitting side and a receiving side, and planning the addresses of the transmitting side and the receiving side into the same subnetwork or the same virtual network; employing token-type communication in a mode of UDP broadcast or multicast, processing messages according to a rule, and achieving in-net one-to-many or many-to-many communication. The method sacrifices certain bandwidth to a certain degree, but greatly improves the reliability and stability of a system, and reduces the complexity of the system.
