Abstract
A high quality network is provided that eliminates the sorting time for sorting through registering look-up conditions, such as source and destination MAC addresses, in a content addressable memory, by generating a routing or flow control look-up key, and then selectively activating some of the physical banks in the content addressable memory with the look-up key during look-up for the look-up conditions. The look-up key is generated by extracting a part or all of the data contained in a packet header.
