A communication method and packet switching system in which packets comprising physical addresses and voice/data information are communicated through the system by packet switching networks which are interconnected by high-speed digital trunks with each of the latter being directly terminated on both ends by trunk controllers. Customer terminals are connected to the switching system by access line controllers which insert the physical addresses into the packets. The line controllers attach to concentrators which are interconnected to the switching networks via high-speed digital trunks. During initial call setup of a particular call, the physical addresses are obtained and stored in the line controllers by the transmission of a cell setup packet and call reply packet between the originating and destination line controllers. Each processor inserts into the call setup packet the necessary addressing information to route packets through the associated network. Each network comprises stages of switching nodes which are responsive to the physical addresses in a packet to communicate this packet to a designated subsequent node.

A communication method and packet switching system in which packets comprising logical addresses and voice/data information are communicated through the system by packet switching networks which are interconnected by high-speed digital trunks with each of the latter being directly terminated on both ends by trunk controllers. During initial call setup of a particular call, central processors associated with each network in the desired route store the necessary logical to physical address information in the controllers which perform all logical to physical address translations on packets of the call. Each network comprises stages of switching nodes which are responsive to the physical address associated with a packet by a controller to communicate this packet to a designated subsequent node. The nodes provide for variable packet buffering, packet address rotation techniques, and intranode and internode signaling protocols. Each packet has a field which is automatically updated by the controllers for accumulating the total time delay incurred by the packet in progressing through the networks.

A trunk controller and processor arrangement for monitoring packet traffic from a high speed trunk through a packet switching network. Within a packet switching system, packets comprising logical addresses and voice/data information are communicated through the system by packet switching networks which are interconnected by high speed digital trunks with each of the latter being directly terminated on both ends by trunk controllers. During initial call setup of a particular call, central processors associated with each network in the desired route store the necessary logical to physical address information in the controllers which perform all logical to physical address translations on subsequent packets of the call. Each network comprises stages of switching nodes which are responsive to the physical address associated with a packet by a controller to communicate that packet to a designated subsequent node. Each trunk controller has a traffic monitoring circuit for measuring the amount of traffic occurring on the attached trunk.

A trunk controller and processor arrangement for measuring packet transmission delay from a first trunk controller through a packet switching network to a second trunk controller. Packets comprising logical addresses and voice/data information are received from high-speed trunks and are communicated through the network to destination trunk controllers which are also attached to high-speed trunks. During initial call setup of a particular call, the central processor associated with the network stores the necessary logical to physical address information in the two controllers associated with that call. The associated controllers then perform all logical to physical address translation on subsequent packets of the call. Each trunk controller comprises a delay monitoring circuit which is responsive to a packet received from the attached trunk to assemble a new switch packet consisting of the arrival time, the physical address, and the received packet for transmission through the network to a destination trunk controller. When a switch packet is received from the switching network by a trunk controller, the delay monitoring circuit of that trunk controller calculates the transmission delay time resulting from the transmission of the packet from the sending trunk controller to the destination trunk controller.

A detection circuit for monitoring the operations of a packet switch node to detect the loss or erroneous creation of packets within the switch node. The switch nodes are interconnected to form a packet switching network, and switching networks are interconnected by trunk controllers to form a packet switching system. A communication path is set up through such a switching system by initially routing a call setup packet from an originating terminal to each central processor controlling a switching network in the route to a destination terminal. Each central processor is responsive to a receipt of the setup packet to store logical to physical address translation information in memories of its associated trunk controllers. The physical address defines a path through the switching network to an output trunk controller in the communication path to the destination terminal. In response to the receipt of each subsequent message packet, each trunk controller utilizes its memory information for translation and the assemblage of a new packet containing the physical address plus the message packet.
