The present disclosure relates to a method of controlling a timeout event for a data packet transmission in a wireless communications network, and a node performing the method. In an aspect, a method of controlling a timeout event for a data packet transmission in a wireless communications network is provided, wherein a data packet retransmission timer initially is set to a timeout value indicating the maximum allowed round-trip time (RTT) for the data packet transmission and a timeout event occurs upon the retransmission timer expiring. The method includes observing the RTT for the data packet transmission over a connection in the network, increasing, upon the retransmission timer expiring before a measured value is available for the observed RTT, the timeout value for the retransmission timer, and determining whether a currently set timeout value for the retransmission timer is to be decreased or not.

Controlling timeout events for data packet transmissions

A method and a first network node for managing a Stream Control Transmission Protocol, 'SCTP' is disclosed. The first network node handles a plurality of computational resources for executing procedures of SCTP at least partially simultaneously. The first network node provides a single instance procedure for managing the SCTP association and multi-instance procedures for managing the SCTP association. Furthermore, the first network node provides a control procedure, being the single instance procedure, for managing flow and acknowledgement of SCTP packets at the SCTP association. The first network node provides the following multi-instance procedures an outgoing transmission procedure for managing and transmitting the SCTP packets from the retransmission buffer, an incoming reception procedure for receiving and managing the SCTP packets, and an outgoing reception procedure for managing and transmitting Upper Layer Protocol frames to the upper layer.
