Network node capable of restricting a packet receiving activity during packet congestion and method thereof

摘要

A network communication node for receiving packets through a network. The network communication node comprises a network communication module for receiving a predetermined number of packets from a predetermined corresponding node linked thereto through a network; a memory for storing first information about a predetermined criterion for reception restriction; and a controller for checking a packet receiving condition of the network communication module and determining whether the criterion for reception restriction is satisfied, and according to a result of the determination, controlling the restriction of the reception of the predetermined packets of the network communication module. Accordingly, the reception of packets is restricted in data congestion, and thus the data congestion can be immediately resolved.
