A system for identifying a subscriber includes an access server coupled to a number of subscribers using a first communication network and further coupled to a second communication network, a memory coupled to the access server, and a processor coupled to the memory. The access server receives a communication from a particular subscriber using a particular one of a number of virtual circuits associated with the first communication network. The memory stores path information that identifies a virtual circuit assigned to the particular subscriber. The processor identifies the particular subscriber for connection to the second communication network based upon the path information and the particular virtual circuit used to receive the communication from the particular subscriber.

System and method for identifying a subscriber for connection to a communication network

A network management system has a bus and a system controller connected to the bus. The bus has a plurality of fixed ports, where each of the ports is capable of connecting a router card to the system controller. A method of sending a file from the system controller to a router card includes receiving a request packet from the router card where the request packet includes a file type and the port address, identifying the file from the file type and the port address, and sending the file to the router card. The system controller has a memory storing the location of files associated with each of the port addresses, a request receiver for receiving a request for a file of a file type from a router card, an identifier for identifying a file, and a sender for sending the identified file to the router card. The router card has a memory for storing an operating system image and a configuration, and a request sender for sending a request for an operating system image and a configuration to the system controller upon power-up of the router card.

Method and apparatus for network management system

A system in which a single VLAN architecture spans multiple VLAN transport protocols and technologies, including a method and system in which multiple different VLANs may be combined in a single enterprise network. Each LAN-switch in the system identifies each frame with an identifier, and associates that identifier with particular VLAN identifiers for each type of VLAN technology. When a frame is bridged or routed from a first type of VLAN to a second type of VLAN, the first VLAN encapsulation is removed and the second VLAN encapsulation is added, with appropriate change in the VLAN identifier for the frame or packet. The identifier may also be implicit for the frame, such as when a particular set of sender's MAC addresses are identified with a particular VLAN. Individual VLANs, of whatever architecture, may be added, configured or reconfigured, modified, or deleted, using control tools associated with the multiple VLAN architecture system. Individual ports may be associated with particular VLANs, or may be designated &ldquo;dynamic&rdquo; so that frames or packets associated with those ports are associated with particular VLANs in response to source or destination addresses or other information.

Multiple VLAN architecture system

A system in which a single VLAN architecture spans multiple VLAN transport protocols and technologies, including a method and system in which multiple different VLANs may be combined in a single enterprise network. Each LAN-switch in the system identifies each frame with an identifier, and associates that identifier with particular VLAN identifiers for each type of VLAN technology.

The identifier may also be implicit for the frame, such as when a particular set of sender's MAC addresses are identified with a particular VLAN. Individual VLANs, of whatever architecture, may be added, configured or reconfigured, modified, or deleted, using control tools associated with the multiple VLAN architecture system. Individual ports may be associated with particular VLANS, or may be designated &ldquo;dynamic&rdquo; so that frames or packets associated with those ports are associated with particular VLANs in response to source or destination addresses or other information.

Individual VLANs, of whatever architecture, may be added, configured or reconfigured, modified, or deleted, using control tools associated with the multiple VLAN architecture system. Individual ports may be associated with particular VLANs, or may be designated 'dynamic' so that frames or packets associated with those ports are associated with particular VLANs in response to source or destination addresses or other information.
