  2. Multicast Group Management (Method 1) • Multicast groups are managed by IEEE 802.1D defined GMRP. • GMRP is an extensive bridge protocol, but can be used in a simplified mode. • The usage of the GARP frames ensures interoperability. • The AP shall have the GMRP registrar. • The source shall have the GARP application entity running as a full applicant. • The source assigns the multicast address and registers them with the Registrar in the AP . • AP propagates the registration information through broadcast. • The receivers may implement “Applicant only” or “Simple Applicant” participants.

  3. Multicast Group Management (Method 2) • The source generates the multicast address. • Maintains a register for all the addresses it has generated. • Adds a receiver to the multicast address when a request for data is received and updates its register. • The multicast address would be propagated by a periodic broadcast message (AP may need to act as a repeater). • Deletes a receiver from the address table if there is no acknowledgement from the receiver (ACK or the delayed ACK) for a certain duration. • May also delete a receiver upon a request from the ESTA to stop sending the data. • Distributed maintenance. • If delayed ACK is desired, a FILTER_SPEC would be needed to allow the HC to merge all requests.
