Abstract
A network switch which can perform in respect of addressed data packets source address and destination address look-ups in a forwarding database includes a control which inhibits the performance of source address look-ups if the length of a respective receive queue of packets is greater than a threshold. The inhibition may endure until the length of the receive queue falls below a second threshold lower than the first. The inhibition may not be applied if the respective receive queue is subject to head of line blocking
