Service interface for QOS-driven HPNA networks
First Claim
1. A method comprising:
- receiving, at a first terminal in a phoneline network, a first message from a second terminal in the phoneline network, the message including an identifier and quality-of-service parameters for a first data flow to be initiated by the second terminal;
in response to the first message, determining scheduling information for the first data flow based on the identifier and the quality-of-service parameters;
sending a second message to indicate a response status for the first message;
receiving a third message including a changed quality-of-service parameter for the first flow; and
updating the scheduling information for the first data flow based on the changed quality-of-service parameter.

Abstract
An in-band signaling model media control (MC) terminal for an HPNA network includes a frame classification entity (FCE) and a frame scheduling entity (FSE) and provides end-to-end Quality of Service (QoS) by passing the QoS requirements from higher layers to the lower layers of the HPNA network. The FCE is located at an LLC sublayer of the MC terminal, and receives a data frame from a higher layer of the MC terminal that is part of a QoS stream. The FCE classifies the received data frame for a MAC sublayer of the MC terminal based on QoS information contained in the received data frame, and associates the classified data frame with a QoS stream queue corresponding to a classification of the data frame. The FSE is located at the MAC sublayer of the MC terminal, and schedules transmission of the data frame to a destination for the data frame based on a QoS requirement associated with the QoS stream.

7. A computer readable memory comprising computer readable instructions which, when executed, cause a first terminal for a phoneline network to perform operations comprising:
-
receiving a first message from a second terminal in the phoneline network, the message including an identifier and quality-of-service parameters for a first data flow to be initiated by the second terminal; in response to the first message, determining scheduling information for the first data flow based on the identifier and the quality-of-service parameters; sending a second message to indicate a response status for the first message; receiving a third message including a changed quality-of-service parameter for the first flow; and updating the scheduling information for the first data flow based on the changed quality-of-service parameter. - View Dependent Claims (8, 9, 10, 11, 12)

13. A first terminal for a phoneline network, the first terminal comprising:
-
memory including computer readable instructions; and a processor to execute the instructions to perform operations including; receiving a first message from a second terminal in the phoneline network, the message including an identifier and quality-of-service parameters for a first data flow to be initiated by the second terminal, wherein the quality-of-service parameters include a maximum delay parameter and a jitter parameter; in response to the first message, determining scheduling information for the first data flow based on the identifier and the quality-of-service parameters; sending a second message to indicate a response status for the first message; receiving a third message including a changed quality-of-service parameter for the first flow; and updating the scheduling information for the first data flow based on the changed quality-of-service parameter. - View Dependent Claims (14, 15, 16, 17)
