    摘要: A network node comprises at least one data plane processor (101) for handling data packets of a first type (144) and for redirecting and rate-limiting data packets of α second type (142). A control plane processor (102) in the network node handles the data packets of α second type (142) redirected by the data plane processor (101). In order to protect the control plane processor (102) against overload, e.g. caused by Denial of Service (DoS) attacks, individual flows of data packets of the second type are identified for enhanced rate-limiting by the data plane processor (101).
