Abstract
A method and apparatus in a network switch port for providing queuing of data frames as they are transferred from a switch port to an external memory. Multiple buffers within the external memory used to store a single data frame are linked together by writing a next buffer location in each buffer header. Storing linking information within each buffer eliminates the need for a separate memory for storing all the buffer locations used to store a data frame, thereby reducing the complexity and cost of the network switch port.
