Abstract
Performing distributed Remote PHY scheduling operations. A low latency scheduler is disposed within or in proximity to a Remote PHY node. Upon identifying that a particular data flow qualifies for processing by the low latency scheduler, the low latency scheduler performs upstream Remote PHY scheduling operations for the particular data flow using a one or more dedicated channels that are designated as low latency channels. The Remote PHY upstream scheduling operations define when data may be transmitted by a Cable Modem (CM) to a Converged Cable Access Platform (CCAP) Core. A centralized scheduler is also located at the CCAP Core. The centralized scheduler performs Remote PHY upstream scheduling operations for all data flows which have not been identified as qualifying for processing by the low latency scheduler.
Claims20
One or more non-transitory computer-readable storage mediums storing one or more sequences of instructions for performing distributed Remote PHY scheduling operations, which when executed, cause:
- upon identifying that a particular data flow qualifies for processing by a low latency scheduler, employing the low latency scheduler, disposed within a Remote PHY node, to perform upstream Remote PHY scheduling operations for the particular data flow using a one or more dedicated channels that are designated as low latency channels;
- and
- employing a centralized scheduler, located at a Converged Cable Access Platform (CCAP) Core, to perform Remote PHY upstream scheduling operations for all data flows which have not been identified as qualifying for processing by the low latency scheduler,
- wherein said Remote PHY upstream scheduling operations define when data may be transmitted by a Cable Modem (CM) to the CCAP Core.
One or more non-transitory computer-readable storage mediums storing one or more sequences of instructions for performing distributed Remote PHY scheduling operations, which when executed, cause:
- upon identifying that a particular data flow qualifies for processing by a low latency scheduler, employing the low latency scheduler, disposed within an entity in close proximity to a Remote PHY node and southbound to a Converged Cable Access Platform (CCAP) Core, to perform upstream Remote PHY scheduling operations for the particular data flow using a one or more dedicated channels that are designated as low latency channels;
- and
- employing a centralized scheduler, located at the CCAP Core, to perform Remote PHY upstream scheduling operations for all data flows which have not been identified as qualifying for processing by the low latency scheduler,
- wherein said Remote PHY upstream scheduling operations define when data may be transmitted by a Cable Modem (CM) to the CCAP Core.
A system for performing distributed Remote PHY scheduling operations, comprising:
- one or more processors;
- and
- one or more non-transitory computer-readable storage mediums storing one or more sequences of instructions, which when executed, cause:
- upon identifying that a particular data flow qualifies for processing by a low latency scheduler, employing the low latency scheduler, disposed within a Remote PHY node, to perform upstream Remote PHY scheduling operations for the particular data flow using a one or more dedicated channels that are designated as low latency channels;
- and
- employing a centralized scheduler, located at a Converged Cable Access Platform (CCAP) Core, to perform Remote PHY upstream scheduling operations for all data flows which have not been identified as qualifying for processing by the low latency scheduler,
- wherein said Remote PHY upstream scheduling operations define when data may be transmitted by a Cable Modem (CM) to the CCAP Core.
