Abstract
A method for congestion control in a network node (20) of a communication network utilizing a distributed queue system for transmission of data units is disclosed. Said network node (20) has a priority queue (PQ) (40) for protocol data units (PDUs) (50, 50a-n) in accordance with a persistent retransmission protocol. The method comprises detecting (110) a condition indicative of a congestion and, in response thereto, manipulating (120) the content of a PDU (50, 50a-n) in the PQ (40). A related network node (20), computer program product, and computer readable medium are also disclosed.
