Method and system of communication

Provided is a method of communication. The method of the communication comprises the following steps: step S101, receiving a connection request signal sent by a client terminal; step S102, detecting whether the connection request signal with two types of frequency is received, and hardware addresses of the connection request signal with the two types of the frequency are uniform, and when the connection request signal with the two types of the frequency is received, and the hardware addresses of the connection request signal with the two types of the frequency are uniform, carrying out step S103; the step S103, detecting whether only one of workloads under two present types of frequency reaches a preset threshold value, and when only one of the workloads under the two present types of the frequency reaches the preset threshold value, carrying out step S104; the step S104, adding the hardware addresses in the connection request into a blacklist which corresponds to frequency , wherein the workload of the frequ
