Abstract :
We have developed a switch access LSI with multiple ports, SAM, which functions as an interface to an ATM switch fabric. It constitutes a switch chipset with another two chips, and it can be used to construct a non-blocking ATM switch. SAM has a unique queueing architecture to achieve remarkable features that include shaping port, per-VC queueing, and flexible multicast. Additionally, SAM provides various ATM layer functions required in most ATM switch systems, i.e., ER mode and EFCI mode of ABR switch behavior with BECN mechanism, frame discarding, EFCI marking, CLP selective discarding, UPC cell tagging and discarding, and automatic OAM cell processing
