1. A method for organizing virtual local area networks, the method comprising the steps of:
- identifying at least one virtual local area network on a network;
organizing the identified virtual local area network into a multicast domain on the network;
designating an organized virtual area network as a multicast virtual local area network of the multicast domain for receiving a multicast message;
assigning an associated station to the multicast domain;
intercepting an Internet Group Management Protocol report targeted for the associated station to identify membership of an IP multicast group;
receiving an IP multicast message for the IP multicast group;
forwarding the IP multicast message to an access point on the multicast virtual local area network; and
transmitting the IP multicast message to the associated station on the multicast domain.

Abstract
A system and method for identifying and grouping multiple virtual local area networks into a single multicast domain is provided. The system and method may be configured to designate a virtual local area network within as a multicast virtual local area network to streamline the delivery of multicast messages via a network. A station may be configured with multiple group keys so that it can receive messages from multiple broadcast or multicast domains.

17. A system for targeting multicast transmission on a network, the system comprising:
-
means for identifying at least one virtual local area network on the network;
means for grouping the identified virtual local area networks into a multicast domain on the network;
means for designating one of the identified virtual local area networks as a multicast virtual local area network for receiving the multicast transmission;
means for assigning an associated station to the multicast domain;
means for identifying membership of the multicast transmission; and
means for transmitting the multicast transmission to the identified members on the multicast virtual local area network. - View Dependent Claims (18, 19, 20, 21)

22. A method for delivering multiple keys, the method comprising:
-
identifying a station associated to at least one domain;
delivering a first encryption key to the station corresponding to a first domain;
delivering a second encryption key to the station corresponding to a second domain;
embedding a key identifier in a header of a message to identify a selected one of the first and second encryption keys;
encrypting the message with the selected one of the first and second encryption keys;
delivering the message and the header; and
selecting a decryption key corresponding to the key identifier. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30, 31)
