Sparse mode system

A computer-implemented method of operating a stream reservation protocol stack of a listener system connected with an Ethernet Audio-Video Bridging (“AVB”) network, the method comprising:

• receiving, through the use of at least one processor, a plurality of stream advertisements from the Ethernet AVB network with a stream reservation protocol stack included in the listener system;
• transmitting, through the use of the at least one processor, the plurality of stream advertisements to an upper layer application included in the listener system when the listener system is functioning in a full mode;
• transmitting, through the use of the at least one processor, a first subset of the received stream advertisements to the upper layer application and not transmitting a second subset of the received stream advertisements to the upper layer application when the listener system is operating in a sparse mode;
• receiving a query from the upper layer application, the query including at least one stream identifier for a data stream of interest to the listener system;
• comparing the plurality of stream advertisements to the at least one stream identifier included in the query when operating in the sparse mode;
• adding each stream advertisement of the plurality of stream advertisements that matches at least one of the at least one stream identifier for the data stream of interest to the first subset of the received stream advertisements based on the comparison;
• and
• adding all stream advertisements of the plurality of stream advertisements that do not match the at least one stream identifier for the data stream interest to the second subset of the received stream advertisements based on the comparison.

A network communication system, comprising:

• an Ethernet Audio-Video Bridging (“AVB”) network;
• a talker in communication with the Ethernet AVB network and configured to advertise a data stream on the Ethernet AVB network with a stream advertisement;
• and
• a plurality of listeners in communication with the Ethernet AVB network and configured to operate in a sparse mode and in a full mode;
• and
• where the plurality of listeners are further configured to compare the stream advertisement to one or more stream identifiers associated with one or more data streams of interest to the listener when operating in the sparse mode, where each of the plurality of listeners comprises:
• a processor;
• an upper layer application executable by the processor, and when executed by the processor, is configured to transmit the one or more stream identifiers associated with the one or more data streams of interest to the listener;
• and
• a stream reservation protocol stack executable by the processor, and when executed by the processor, is configured to:
• receive the one or more stream identifiers associated with the one or more data streams of interest to the listener;
• receive the stream advertisement on the Ethernet AVB network from the talker, the stream advertisement comprising a stream identifier identifying the data stream being advertised by the talker;
• and
• operate in a sparse mode and a full mode;
• where the stream reservation protocol stack, when operating in the sparse mode, is further configured to:
• transmit the stream advertisement received on the Ethernet AVB network to the upper layer application in response to the stream identifier identifying the data stream advertised by the talker included in the stream advertisement matching at least one of the one or more stream identifiers received by the stream reservation protocol stack, and
• not transmit the stream advertisement received on the Ethernet AVB network to the upper layer application in response to the stream identifier identifying the data stream advertised by the talker included in the stream advertisement not matching the one or more stream identifiers received by the stream reservation protocol stack;
• and
• where the stream reservation protocol stack, when operating in the full mode, is further configured not to compare the received stream advertisements with the one or more stream identifiers received by the stream reservation protocol stack.

One or more non-transitory computer readable media tangibly embodying computer executable code for operating a stream reservation protocol stack of a listener system connected with an Ethernet Audio-Video Bridging (“AVB”) network, said media comprising:

• code for receiving a plurality of stream advertisements from the Ethernet AVB network with a stream reservation protocol stack included in the listener system;
• code for transmitting the plurality of stream advertisements to an upper layer application included in the listener system when the listener system is functioning in a full mode;
• code for transmitting a first subset of the received stream advertisements to the upper layer application and not transmitting a second subset of the received stream advertisements to the upper layer application when the listener system is operating in a sparse mode;
• code for receiving a query from the upper layer application identifying a data stream of interest to the listener system;
• code for comparing, when operating in the sparse mode, the plurality of stream advertisements to a stream identifier included in the query, the stream identifier uniquely identifying the data stream of interest;
• code for adding, when operating in the sparse mode, each stream advertisement of the plurality of stream advertisements that matches the stream identifier to the first subset of the received stream advertisements based on the comparison;
• and
• code for adding, when operating in the sparse mode, all stream advertisements of the plurality of stream advertisements that do not match the stream identifier to the second subset of the received stream advertisements based on the comparison.
