A method for link aggregation of a plurality of communication links, performed in a communication arrangement, the method comprising;

Link aggregation with data segment fragmentation

The present disclosure relates to a communication arrangement () adapted for link aggregation of a plurality of communication links (). The communication arrangement () is adapted to communicate via the plurality of communication links () and comprises a traffic handling unit () that is adapted to obtain data segments (---) to be transmitted, and to identify one or more data flows () in said data segments. The traffic handling unit is adapted to attach sequence numbers, SEQ, to data segments associated with each identified data flow (), wherein sequence numbers are independent between data flows and to select a communication link for transmission of a data segment associated with a certain data flow (). The selecting comprises selecting a previous communication link that has been used for transmission of a previous data segment from said certain data flow () if possible, and selecting any communication link otherwise.

Link aggregation with receive side buffering

The present disclosure relates to a communication arrangement () adapted for link aggregation of a plurality of communication links (), comprised in an Aggregation Group, AG, (). The communication arrangement () is adapted to communicate via the plurality of communication links () and comprises a traffic handling unit () that is adapted to obtain data segments (-) to be transmitted, and to determine a risk of re-ordering of data segments within a certain data flow () comprising a certain data segment (). Said risk is associated with transmitting said certain data segment via a certain communication link out of the plurality of communication links (). The traffic handling unit () is furthermore adapted to buffer said certain data segment () until the risk of re-ordering satisfies a predetermined criteria, prior to transmitting the said certain data segment () via the selected communication link.
