Abstract:
1. A method for dynamically fragmenting packets by a node in a communications network, said method comprising: generating a plurality of fragments by splitting a packet based on a value of a fragment size parameter; sending a first fragment of said plurality of fragments to a receiving node; determining a value of a transmission success parameter for the first fragment, the transmission success parameter indicating whether the first fragment was successfully received; updating a value of a link quality parameter based on the value of the transmission success parameter, the value of the link quality parameter representing a chance a second fragment having the same size as the first fragment will be successfully received; comparing the value of the link quality parameter and a value of a quality threshold parameter; and changing the value of the fragment size parameter based on a result of the comparison, wherein the method further comprises preventing an increase of the value of the fragment size parameter for a predetermined period of time after the link quality parameter falls below the third threshold value.
