Estimating the term…
The switch fabric of the ATM switch, i.e., the ATM switch backplane bus, switches a cell based on routing information provided by the source LAN or ATM module to an output port on a destination LAN or ATM module of the switching hub. In the described system, the ATM switch is preconfigured to provide a fully connected topology between ports of all modules. In one embodiment, ATM cells transmitted across the ATM switch fabric between a source LAN or ATM module and a destination LAN module, e.g., Token Ring, FDDI or Ethernet, is accomplished by way of a routing tag prepended on the ATM cells. The routing tag provides both unicast and multicast group destination information such that the ATM cells are routed to the appropriate port on a given destination module without the need to establish a virtual circuit between the source module and the destination module using VPI/VCIs.
An apparatus having stored therein a tag coupled to a data cell for specifying a destination of said data cell transmitted on a data bus, said tag comprising:
An asynchronous transfer mode switch, hereafter referred to as an ATM switch, having stored therein a tag coupled to a cell for identifying a port on said ATM switch to which said cell is transmitted, said tag comprising:
An asynchronous transfer mode switch, hereafter referred to as an ATM switch, having a backplane bus, a plurality of modules coupled thereto, each one of said plurality of modules having a plurality of ports, said ATM switch for processing a tag associated with a data cell transmitted on said backplane bus, wherein said tag comprises:
In an asynchronous transfer mode switch, hereafter referred to as an ATM switch, a method of transmitting a data cell between a first module and a port on a second module, said first module and said second module coupled to a data bus comprising the steps of said first module:
An apparatus associated with a data communication network, said apparatus to store a tag associated with a data cell, said tag for indicating routing of said data cell in said data communication network, said apparatus comprising:
