Vermittlungssystem mit einer Eingangsverteilstufe für zeitmarkierte Pakete und mit einer Ausgangsstufe für die Gewährleistung der richtigen Reihenfolge der Pakete

摘要

In a fast packet switching system, packet distributers are associated respectively with input ports for receiving successive packets therefrom and attaching a timeslot number to each of the received packets, and uniformly distributing the packets to output terminals of each distributer. Packet switches are provided corresponding in number to the output terminals of each packet distributer. Each packet switch has input terminals corresponding in number to the packet distributers and output terminals corresponding in number to the output ports. The input terminals of each packet switch are coupled to respective output terminals of the distributers for switching a packet from one of its input terminals to one of its output terminals in accordance with a destination address contained in the packet. Packet sequencers are associated respectively with the output ports. Each packet sequencer has input terminals coupled to respective output terminals of the packet switches for examining the timeslot numbers attached to packets from its input terminals and delivering the packets to the associated output port in accordance with the examined timeslot numbers.
