The method includes: receiving a punted-to-control-plane bandwidth rate value currently required by at least one protocol, the control plane traffic bandwidth rate value currently required by the at least one protocol being obtained from current status information of the at least one protocol; and assigning a bandwidth for the at least one protocol in accordance with the punted-to-control-plane bandwidth rate value currently required by the at least one protocol. The method ensures that the bandwidth assigned by the forwarding engine module for each protocol conforms to the practical circumstance of the protocol, and makes it possible that normal operation of the protocol is not only satisfied, but the bandwidth of the CPU channel is also not wasted due to excessive assignment. ## Claims ### Claim 1 A method for dynamic correlation of control plane traffic rate, comprising: receiving a punted-to-control-plane bandwidth rate value currently required by at least one protocol, the punted-to-control-plane bandwidth rate value currently required by the at least one protocol being obtained from current status information of the at least one protocol;
