Abstract
An address look-up data-base is used to store medial access control addresses for resolution into channel numbers in a system for transmitting data in an asynchronous transfer mode. Static random access memory is used to contain pointer tables, there being a pointer table for each possible priority level in the data packet. Thus a search for the media access control address of a data packet in the content addressable memory yields, among other data, a priority value which when combined with other data points to a location in one of the pointer tables, which accesses the appropriate channel number.
