Title: Integrated packetized voice and data switching system
Inventor: HEMMADY JAYANT G
IPC: H04L12/56
Filed: 1989-03-29
Granted: 1992-12-29
Abstract: INTEGRATED PACKETIZED VOICE AND DATA SWITCHING SYSTEM Abstract A high capacity metropolitan area network (MAN) is described. Data traffic from users is connected to data concentrators at the edge of the network, and is transmitted over fiber optic data links to a hub where the data is switched. The hub includes a plurality of data switching modules, each having a control means, and each connected to a distributed control space division switch. Advantageously, the data switching modules, whose inputs are connected to the concentrators, perform all checking and routing functions, while the 1024x1024 maximum size space division switch, whose outputs are connected to the concentrators, provides a large fan-out distribution network for reaching many concentrators from each data switching module. Distributed control of the space division switch permits several million connection and disconnection actions to be performed each second, while the pipelined and parallel operation within the control means permits each of the 256 switching modules to process at least 50,000 transactions per second. The data switching modules chain groups of incoming packets destined for a common outlet of the space division switch so that only one connection in that switch is required for transmitting each group of chained packets from a data switching module to a concentrator. MAN provides security features including a port identification supplied by the data concentrators, and a check that each packet is from an authorized source user, transmitting on a port associated with that user, to an authorized destination user that is in the same group (virtual network) as the source user. This arrangement can also be used to switch voice packets, using a voice interface such as a digital switch and a digital voice signal to voice packet converter. In accordance with one embodiment of the invention, a packet switch is used for switching voice packet outputs of the data switching modules and a circuit switch, such as the space division switch, is used for switching data packet outputs. In accordance with another embodiment, voice packets are switched from the data switching modules through the space division switch to a small group ofdata switching modules, which further switch the voice packets through the circuit switch to a destination concentrator.
