Abstract

A method of managing the allocation to TCP connections of memory blocks of a TCP re-assembly buffer in a TCP network device including a TCP Processing unit, comprises computing a function r(t) on a per connection basis, that measures the occupancy rate of the re-assembly buffer for the relevant TCP connection, and that is updated upon reception of any packet belonging to said TCP connection; and allowing the TCP connection to be closed and the corresponding memory blocks to be released based on a decision scheme that includes at least a first trigger set on the corresponding function r(t), which defines two different states for said function r(t).
