Abstract
A method of managing transport of packets transmitted over a time division multiplexed, TDM, link in a network. The method performed at a second network node comprises: receiving (102) blocks of data from a first network node. Data from one packet is received in a plurality of blocks and a first block from a packet has a time-stamp indicating arrival time of the packet at the first network node. The blocks are multiplexed for transmission over the TDM link. The method also comprises: queuing (106) the received blocks and if a block from the top of the queue (108, 110) has a time-stamp (110—yes) and a maximum allowed latency has been exceeded (112) the method discards (116) blocks containing data from the same packet as the block with said time-stamp if there is at least one block containing data from another packet in the queue (114—yes). An apparatus is also disclosed.
