Abstract
There is disclosed a system for monitoring a packet data flow, comprising: a data flow source element including: determining means adapted to determine a quality of service identifier for the data flow; first generating means adapted to generate an encoded value in dependence on the quality of service identifier; allocating means adapted to allocate the quality of service identifier and the encoded value to the flow label for each data packet of the data flow; and transmitting means for forwarding data packets including flow labels to a routing domain; and a routing domain interface element including: receiving means for receiving data packets from the data flow source; second generating means adapted to generate a further encoded value in dependence on the quality of service identifier in a flow label of a data packet; comparing means adapted to compare the further encoded value to the encoded value in the flow label; and routing means adapted to selectively route the data packets in dependence on the comparing step.
