A network node (100) comprises an optical input and an optical output. It receives one or more complete data packets, at a first data rate, at the input during a time window. If an incomplete data packet is received during the time window, it extends the time window (5970) and receives the complete data packet. It transmits (5990) all the complete data packets received in the original or extended time window from the output at a second data rate, faster than the first data rate, with the data packets and any gaps between adjacent data packets being in the same order as the node received them, and with a substantially uniform time compression factor applied to the data packets and to any gaps between adjacent data packets. |
