A New Type of PPS Switches
一种新型的PPS交换机

Parallel Packet Switch (PPS) can realize high speed switching by using low speed switches, which is a hot spot in switching area. So, this paper analyzes the current situation, and presented the PPS_RR scheduling algorithm by using the concept of flow index. The math analyzing validates that the system can guarantee packet sequence in a data flow. Finally, computer simulation shows the type of PPS has good performance on average delay.
