Link aggregation based on estimated time of arrival

A communication arrangement adapted for link aggregation of a plurality of communication links, the plurality of communication links comprised in an Aggregation Group (AG), the communication arrangement configured to communicate via the plurality of communication links, the communication arrangement comprising:

• a traffic handling unit, the traffic handling unit comprising processing circuitry and memory containing instructions executable by the processing circuitry whereby the traffic handling unit is operative to:
• implement link aggregation of the plurality of communication links in the AG for a plurality of data flows, each data flow comprising a succession of data segments, by transmitting each successive data segment of a given data flow via any available link of the aggregated communication links;
• for each of a plurality of data flows, obtain data segments to be transmitted;
• for a certain data segment,
• identify a subset of available communication links, out of the plurality of communication links, which are available for transmission of the certain data segment within a current time period;
• if a communication link used for transmission of a most recently transmitted data segment of a certain data flow comprising the certain data segment is in the subset of available communication links, select that communication link, and otherwise, select any communication link comprised in the subset of available communication links;
• determine a risk of reordering of data segments within the certain data flow, where the risk is associated with transmitting the certain data segment via the selected communication link, based on its link characteristics;
• and
• buffer the certain data segment until the risk of reordering satisfies a predetermined criteria, prior to transmitting the certain data segment via the selected communication link.
