SSN is an ultra high radix single switch fabric targeted towards ultra high throughput computing systems. It features a single cycle least recently granted arbitration technique that re-uses data buses and switching logic. It also integrates 4-level message based priority arbitration for quality of service and unique bidirectional bit-line repeaters for improved scalability. 

Details on circuit techniques and measurement results from our test prototype will be disclosed at ISSCC 2012 in the paper entitled "A 4.5Tb/s 3.4Tb/s/W 64×64 switch fabric with self-updating least recently granted priority and quality of service arbitration in 45nm CMOS".
