Abstract

A method performed by a network element in a communication network comprises inspecting traffic between a radio device and the communication network. The method also comprises, based on said inspecting, determining that the traffic is part of a TCP subflow of an MPTCP connection. The method also comprises, based on said inspecting, calculating a ratio of how much data is transmitted in the subflow in relation to the total amount of data transmitted in the MPTCP connection over a predetermined time period. The method also comprises observing that the calculated ratio is below a reference ratio. The method also comprises, based on said observing, performing an action for preventing congestion in the communication network.
