[0012] The notification of OSPF link information adopts a diffusion mechanism, that is, when receiving link status update information from a neighbor, it will perform a diffusion operation to other interfaces, and at the same time install newer link information in the local database. SPF calculation needs to be arranged, refer to figure 2 , according to the number of current retransmission lists, dynamically adjust the scheduled reception rate of the message. The adjustment algorithm here adopts the principle of negative feedback, that is, if the current number of retransmission lists is large, a smaller scheduled reception rate is determined, and vice versa , then determine a larger receiving rate, of course, the determination of the specific rate is also related to the processing power of the CPU and the size of the memory. If the receiving rate of the message is greater than the predetermined receiving rate, the update message is discarded; otherwise, the update message is...
