Abstract
Elastic capacity management of remote physical layer (R-PHY) nodes with a cloud Cable Modem Termination System (cCMTS) may be provided. First, a cCMTS instance may be spawned by an orchestrator. Next, the cCMTS instance may be synchronized with states of a physical Cable Modem Termination System (pCMTS). Underlay routing may then be configured between a plurality of remote physical layer (R-PHY) nodes and the cCMTS instance. Then a plurality of R-PHY node connections respectively corresponding to the plurality of R-PHY nodes may be switched from the pCMTS to the cCMTS instance.
Claims20
A method comprising:
- spawning, by an orchestrator, a cloud Cable Modem Termination System (cCMTS) instance;
- synchronizing the cCMTS instance with states of a physical Cable Modem Termination System (pCMTS), wherein synchronizing the cCMTS instance comprises:
- synchronizing the cCMTS instance on a second data path different from a first data path between a plurality of remote physical layer (R-PHY) nodes and the pCMTS, and
- shutting down a third data path between the plurality of remote physical layer (R-PHY) nodes and the cCMTS instance;
- configuring underlay routing between the plurality of R-PHY nodes and the cCMTS instance;
- and
- switching on the third data path comprising a plurality of R-PHY node connections respectively corresponding to the plurality of R-PHY nodes from the pCMTS to the cCMTS instance.
A system comprising:
- a memory storage;
- and
- a processing unit coupled to the memory storage, wherein the processing unit is operative to:
- spawn a cloud Cable Modem Termination System (cCMTS) instance;
- synchronize the cCMTS instance with states of a physical Cable Modem Termination System (pCMTS) obtained from a database, wherein the processing unit being operative to synchronize the cCMTS instance comprises the processing unit being operative to:
- synchronize the cCMTS instance on a second data path different from a first data path between a plurality of remote physical layer (R-PHY) nodes and the pCMTS, and
- shut down a third data path between the plurality of R-PHY nodes and the cCMTS instance;
- configure underlay routing between a plurality of R-PHY nodes and the cCMTS instance;
- and
- switch on the third data path comprising a portion of a plurality of R-PHY node connections respectively corresponding to a portion of the plurality of R-PHY nodes from the pCMTS to the cCMTS instance.
A non-transitory computer-readable medium that stores a set of instructions which when executed perform a method executed by the set of instructions comprising:
- spawning a cloud Cable Modem Termination System (cCMTS) instance;
- synchronizing the cCMTS instance with states of a physical Cable Modem Termination System (pCMTS) obtained from a database, wherein synchronizing the cCMTS instance comprises:
- synchronizing the cCMTS instance on a second data path different from a first data path between a plurality of remote physical layer (R-PHY) nodes and the pCMTS, and
- shutting down a third data path between the plurality of R-PHY nodes and the cCMTS instance;
- configuring underlay routing between the plurality of R-PHY nodes and the cCMTS instance;
- and
- switching on the third data path comprising a plurality of R-PHY node connections respectively corresponding to the plurality of R-PHY nodes from the pCMTS to the cCMTS instance.
