ABSTRACT:
Multiple network switches are configured having memory interfaces that transfer segmented frame data to each other via a data path having multiple rings connecting the network switches. The memory interfaces are also configured for transferring the segmented frame data to respective local buffer memories for temporary storage. The data path transfers the data units between the switches according to a prescribed sequence protocol, optimizing memory bandwidth by requiring only one read and one write operation to and from a local buffer memory for each segmented frame data being received and transmitted through the switches.
