  • Patent number: 11909649
    Abstract: Described herein is a system and method for a microservices architecture for dynamic channel migration based on real time traffic load. Traffic loads on a first and second radio frequency (RF) channels used by a transceiver to communicate with a plurality of modem devices may be monitored, where the first RF channel is transmitted at a higher frequency than the second RF channel. Based on the monitored traffic loads of the RF channels, data traffic may be migrated from the first RF channel to the second RF channel. Finally, the plurality of modem devices may be notified of the migration.

  • Patent number: 11775402
    Abstract: Ensuring the high availability of a Passive Optical Network (PON). A broadband network architecture comprises (a) at least a portion of optical fiber in a communication path to individual subscriber premises, (b) one or more software-implemented Optical Line Terminal (OLT) Controllers, (c) one or more software-implemented Service Provisioning Applications (SPAs), and (d) one or more software-implemented Broadband Network Gateways (BNGs). Each of the one or more OLT Controllers, one or more SPAs, and one or more BNGs execute on Commercial Off-the-Shelf (COTS) computer systems and entirely upon a plurality of protection groups. Each of the plurality of protection groups consists of a plurality of pods. The pods in a particular protection group which are active are dynamically adjusted to ensure the high availability of the broadband network architecture.

  • Patent number: 11321200
    Abstract: A Cable Modem Termination System (CMTS) providing high speed data services to one or more remote physical devices (RPDs). The CMTS executes entirely upon a plurality of protection groups. Each of the plurality of protection groups consists of a plurality of pods. A dynamic adjustment may be made as to which pods in a particular protection group are active. The dynamic adjustment is made response to determining that a particular protection group is experiencing a failure. This determination may be made by a high availability agent executing within a pod, of the particular protection group, that is experiencing the failure. Software associated with supporting a particular service group of the CMTS may be upgraded without upgrading the software associated with supporting the remainder of the plurality of service groups serviced by the CMTS.

  • Publication number: 20200343988
    Abstract: Systems, apparatuses, and methods are described for synchronization based on time differentials in an access network. A time domain may be established for a virtual service and a remote node. The virtual service may synchronize to a clock associated with the remote node based on a time differential. Various virtual services may maintain their own time domains with remote nodes.

  • Publication number: 20170272979
    Abstract: Systems for network based control of wireless gateway communications are described. Each network wireless gateway and secondary network device may collect parameters and data regarding communications with connected wireless devices. The collected data may be aggregated at a Network Traffic Scheduler (“NTS”), which may use the data to identify conflicts in communications with wireless devices. If the NTS determines there are conflicts in the communications with particular wireless devices, the NTS may communicate instructions for adjusting the operations of the network so as to avoid or mitigate continued conflicting communications. In response to user requests for a particular level or quality of service, the NTS may communicate instructions for adjusting the operations of the network so as to satisfy the requested level of service.
