Abstract:

PPS (parallel packet switch) can realize high speed switching by using multiple low speed switches. This kind of switch has become a hotspot in high speed switching area. In this paper, we firstly analyzed the current situation of the PPS. Then a new frame based PPS with a new scheduling algorithm was presented. Mathematic analyses showed that this switching architecture can guarantee delay bound and the sequence of the packet.

Key words: delay bound, parallel packet switch, buffered crossbar switches
