A method for using a node in a home communications network, the home communications network including a plurality of nodes and a coaxial cable, the method comprising:

• receiving, from an entry node, a confirmation message in at least one of the TLV TYPE, TLV LENGTH and TLV VALUE fields of a Device Attribute Information Element in L2ME protocol, the confirmation message comprising an indication to confirm a node of the plurality of nodes selected by the entry node to support an audio/video bridging (AVB) service on the home communications network, wherein the entry node and a network controller node are each one of the plurality of nodes and said TLV TYPE, TLV LENGTH and TLV VALUE fields include vendor specific fields;
• distributing, from a network controller (NC) node, the confirmation message to the plurality of nodes;
• in response to the confirmation message, receiving an acknowledgment message from the plurality of nodes,
• wherein the plurality of nodes that can be selected for supporting the AVB service on the network are Multiple Stream Reservation Protocol (“MRSP”) nodes;
• and
• wherein the network controller node cannot be selected to support the AVB service.

A method for using a node in a home communications network, the home communications network including a plurality of nodes and a coaxial cable, the method comprising:

• receiving, from an entry node, a confirmation message in vendor specific fields of a protocol, the protocol for use in conjunction with the home communications network, the confirmation message providing an indication to confirm a node of the plurality of nodes selected by the entry node to support an audio/video bridging (AVB) service on the home communications network;
• distributing the confirmation message to the plurality of nodes;
• and
• in response to the confirmation message, receiving an acknowledgment message from the plurality of nodes.

A network controller node in a home communications network, the home communications network including a plurality of other nodes and a coaxial cable, the network controller node configured to:

• receive a confirmation message from an entry node regarding an audio/video bridging (“AVB”) service on the home communications network, the confirmation message containing at least one of a plurality of vendor specific fields of a protocol, the protocol for use in conjunction with the home communications network, the confirmation message comprising an indication to confirm a node of the plurality of other nodes selected by the entry node to support the AVB service on the home communications network;
• distribute the confirmation message to the plurality of other nodes;
• and
• in response to the distribution of the confirmation message, receive an acknowledgment message from the plurality of other nodes;
• wherein the plurality of other nodes that can be selected for supporting the AVB service on the network are Multiple Stream Reservation Protocol (“MSRP”) nodes, and
• wherein the network controller node cannot be selected to support the AVB service.

An entry node for use in a home communications network, the home communications network including a plurality of nodes and a coaxial cable, the entry node configured to:

• submit a query message in at least one of selected fields of a Device Attribute Information Element in L2ME protocol, the entry node being a node that requires an audio/visual bridging (“AVB”) service, the entry node not possessing information regarding as to which node of the plurality of nodes is capable of supporting the AVB service on the home communications network, wherein the entry node and a network controller node are each one of the plurality of nodes and said selected fields include a plurality of vendor specific fields, wherein the query message is distributed to the plurality of nodes by the home communications network,
