Abstract
In one example, a resource manager for an edge device is configured to intelligently distribute streams over the RF channel interface of the edge device. As a result of this intelligent stream distribution by the resource manager, the likelihood that the edge device can power down inactive internal components is significant, especially during periods of low activity.
Claims20
A processor readable medium encoded with instructions that, if executed, result in:
- generating a table of Radio Frequency (RF) channels extending from an Edge Quadrature Amplitude Modulator (EQAM);
- identifying in the table at least a first subset of the RF channels and a second different subset of the RF channels, wherein all the RF channels of the first subset are operationally dependent on the power state of a common hardware component of the EQAM, and wherein none of the RF channels of the second subset are operationally dependent on the power state of such hardware component of the EQAM;
- communicating the associations between the RF channels to an Edge Resource Manager (ERM);
- and
- placing streams on the RF channels according to control signaling from the ERM.

A processor readable medium encoded with instructions that, if executed, result in:
- generating a table mapping service groups to hardware domains, wherein each hardware domain includes a different subset of Radio Frequency (RF) channels of an Edge Quadrature Amplitude Modulator (EQAM);
- in response to receiving a request for a data stream, comparing a service group indicated by the data stream request to the generated table to identify corresponding ones of the hardware domains;
- selecting one of the identified hardware domains;
- and
- causing the EQAM to process the requested data stream using an RF channel of the selected hardware domain.

A method, comprising:
- generating a table mapping groups of receivers to domains representing different hardware portions of an edge device;
- in response to receiving a request for a data stream, comparing a receiver group indicated by the data stream request to the generated table to identify corresponding ones of the domains;
- selecting one of the identified hardware domains;
- and
- causing the edge device to process the requested data stream using an RF channel corresponding to the selected domain.
