A method of preventing network denial of service attacks by early discard of out-of-order segments comprises creating a reassembly queue for a connection between a first network node and a second network node, wherein the connection has been established based on a transport-layer network protocol, the reassembly queue having a size based on a buffer size of an input interface with which the connection is associated. As out-of-order data segments arrive on the connection, and before other processing of the segments, whether the reassembly queue is full is determined, and the out-of-order segments are discarded if the reassembly queue is full. The size of the reassembly queue is automatically changed in response to one or more changes in any of network conditions and device resources.
