A network communications device is arranged to have a fast throughput of data packets. This is achieved by recognising that, in protocols such as Ethernet, the first symbols in a data packet do not carry any data and therefore do not necessarily require to be properly carried through a communications hub. Rather, a known number of symbols J,K are discarded from the start of a packet on receipt and replaced on re-transmission. This discarding reduces the reception delays particularly in 100 Mbps bussed-architecture repeaters where bus arbitration must take place for each received packet. |
