Abstract

A new data packet cell control method and apparatus, particularly, though not exclusively, for use with I/O packet cell source and destination resource networks using shared central multi-port internally cached dynamic random access memory (AMPIC DRAM), wherein a separate control path architecture is used, also incorporating AMPIC DRAM technology, to obviate problems with data traffic congestion resulting from significant I/O resource and for bandwidth requirement increases, and doing so while enabling scaling with data path, and retaining quality of service and increased multicast functionality, as well.
