The invention provides a cross-platform live broadcast visitor data fusion and routing load balancing method and system, and relates to the technical field of load balancing, and the method comprises the steps: filtering repeated visitor identifiers through a Bloom filter array, calculating the number of independent visitors through a logarithm radix counting algorithm, and dividing the priority of the visitors based on a data flow entropy value; constructing an annular routing structure by using a consistent Hash algorithm, mapping visitors to virtual nodes, and performing fragmentation routing based on priorities; the response time of the virtual nodes is recorded in real time, abnormal nodes are identified, associated visitors are migrated to standby nodes, and dynamic load balancing is achieved; the visitor data processing efficiency and the system stability of the live broadcast platform are effectively improved, the load pressure of the server is reduced, and the fluency of the live broadcast service is guaranteed.
