Abstract
A communication device is arranged to transmit data segments over an interface, wherein the communication device comprises transmission management logic. In response to receipt of a data segment for transmission over the interface, the transmission management logic is arranged to determine a sequence number of a data segment to be transmitted and compare the sequence number of the data segment to be transmitted with at least one pending sequence number of a previous data segment. Based on the comparison, the transmission management logic either discards the data segment to be transmitted if the sequence number of the data segment to be transmitted matches the at least one pending sequence number of the previous data segment; or adds the sequence number of the data segment to be transmitted to the at least one pending sequence number and transmits the data segment over the interface if the sequence number of the data segment to be transmitted does not match the at least one pending sequence number.
