Abstract

A method (400) for optimizing bandwidth utilization in a communications network (100). The communications network can include a data source (105) and a data client (110). Responsive to a measurement of at least one communication parameter (120) of a commutated bitstream (115) which is transmitted to the client, the data source can change a commutation format of the commutated bitstream. The communication parameters can include a data receive time (TRX), a data latency and/or an effective receive data rate (DEff) of the commutated bitstream. The communication parameters can be transmitted to the data source as telemetry. The change of commutation format can occur in an open systems interconnection (OSI) layer such as a session layer and/or a transport layer.

Claims (10)

responsive to a measurement of at least one communication parameter of a commutated bitstream which is transmitted to a data client, changing a commutation format of the commutated bitstream.
2. The method according to claim 1, further comprising selecting the at least one communication parameter to comprise at least one parameter selected from the group consisting of a data receive time (T Rx), a data latency, and an effective receive data rate (D Eff) of the commutated bitstream.
3. The method according to claim 2, wherein the changing a commutation format step further comprises:
comparing the data receive time (T Rx) to a data transmit time (T Tx) to determine the data latency;
based on the data latency, selecting a new commutation format definition; and formatting the commutated bitstream with the new commutation format definition.
4. The method according to claim 2, wherein the changing a commutation format step further comprises:
comparing the effective receive data rate (D Eff) to a transmit data rate (D Tx) to determine a data rate difference;
based on the data rate difference, selecting a new commutation format definition; and formatting the commutated bitstream with the new commutation format definition.
5. The method according to claim 2, wherein the changing a commutation format step further comprises:
comparing the data receive time (T Rx) to a data transmit time (T Tx) to determine a data latency;
comparing the effective receive data rate (D Eff) to a transmit data rate (D Tx) to determine a data rate difference;
based on the data latency and the data rate difference, selecting a new commutation format definition; and formatting the commutated bitstream with the new commutation format definition.
6. The method according to claim 1, further comprising defining the changing a format step to occur in at least one open systems interconnection (OSI) layer selected from the group consisting of a session layer and a transport layer.
7. A data source comprising:
a commutation engine that changes a commutation format of a commutated bitstream being transmitted to a data client responsive to a measurement of at least one communication parameter of the commutated bitstream.

9. The data source of claim 8, wherein a data source process for changing the commutation format operates in at least one open systems interconnection (OSI) layer selected from the group consisting of a session layer and a transport layer.
10. A communications network comprising:
a data source comprising a commutation engine; and a data client comprising a decommutation engine;
wherein the data client measures at least one communication parameter of a commutated bitstream received from the data source and transmits the at least one communication parameter to the data source; and wherein the data source changes a commutation format of the commutated bitstream responsive to receiving the at least one communication parameter.
