Abstract: The present invention provides a method and device of load-sharing in an IRF stack. The method includes: the Master device checking a congestion state of the main path, obtaining a path for forwarding service flow according the congestion state of the main path, where the path is the main path or a backup path, and forwarding the service flow to the egress device through the main path or the backup bath to implement the load-sharing in the IRF stack. In the embodiments of the present invention, by checking the congestion states of main path and the backup path in real-time, the load-sharing of the IRF stack is implemented. When new service flow is added, the data may be forwarded through another path, which can improve the efficiency of member devices in the IRF stack and solve the problem of forwarding bottleneck to which the member devices face.
