User-based binding of network stations to broadcast domains
First Claim
1. A method for binding a first network station to one or more VBDs, wherein the first network station has one or more ports for connection to a physical network, the method comprising:
- the first network station receiving a user identification of a user logging on to the first network station;
the first network station sending to at least one of the one or more ports a request to be bound to one or more VBDs determined based on information comprising the user identification, wherein the request to be bound to the one or more VBDs uses a first logical address as an address of the first network station;
the first network station requesting a release of the first logical address; and
the first network station sending a request for a second logical address for communication over the one or more VBDs.

Abstract
A broadcast or multicast message from a network station is forwarded only to stations in the same virtual broadcast domain (VBD) as the sending station. In some embodiments, a VBD is virtual network (VLAN) or a workgroup (a group of stations, possibly within a VLAN). A membership of a network station in a VBD is determined based on the user who logged on to the station. When the station is first powered up, it is bound to a "default" VBD. When a user logs on, the VBD(s) assigned to the user are determined, and the user'"'"'s station is switched to the VBD(s). When the user logs off, the user'"'"'s station is returned to the default VBD.

1. A method for binding a first network station to one or more VBDs, wherein the first network station has one or more ports for connection to a physical network, the method comprising:
-
the first network station receiving a user identification of a user logging on to the first network station; the first network station sending to at least one of the one or more ports a request to be bound to one or more VBDs determined based on information comprising the user identification, wherein the request to be bound to the one or more VBDs uses a first logical address as an address of the first network station; the first network station requesting a release of the first logical address; and the first network station sending a request for a second logical address for communication over the one or more VBDs. - View Dependent Claims (2, 3, 4, 5)

15. A method for binding network stations to VBDs, the method comprising:
-
receiving a request to bind a network station to one or more VBDs; determining one or more VBDs to which the network station is to be bound, wherein the one or more VBDs are determined using an identification of a user who logged on to the network station; sending a response to the request; waiting for the network station to release the network station'"'"'s logical address used in the request to bind the network station to the one or more VBDs; and after waiting for the network station to release the logical address, issuing a command to bind the network station to the one or more VBDs. - View Dependent Claims (16, 17, 18, 19)
