Abstract:
A Wide Area Network (WAN) arrangement including a connection fabric and terminal points for accessing said connection fabric, where said terminal points are adapted for connecting LAN Emulation Clients (LECs), where a LEC of said LECs is coupled to an associated LAN that allows at least one device coupled to said LAN to communicate with to other devices coupled to said LAN or to communicate via said connection fabric to a device coupled to a LAN associated with another LEC, said WAN further comprising:a LAN Emulation Server (LES) with memory that maintains binding information about devices coupled to LANs of LECs, where the binding information about a device associates a unique address that identifies said device with an address of the LEC that is associated with the LAN to which said device is coupled, and a controller for updating said binding information of said device in response to a signal sent by a LEC whenever the LEC recognizes that said device coupled to its LAN is not known to the LEC to be coupled to its LAN.
