High availability of a passive optical network (pon)
A recently granted patent (Publication Number: US11775402B2) describes a technology for ensuring the high availability of a Passive Optical Network (PON). The patent outlines a broadband network architecture that includes optical fiber communication paths to individual subscriber premises, software-implemented Optical Line Terminal (OLT) Controllers, Service Provisioning Applications (SPAs), and Broadband Network Gateways (BNGs). These components execute on Commercial Off-the-Shelf (COTS) computer systems and operate within protection groups consisting of multiple pods.
The patent claims that the technology enables dynamic adjustment of active pods within a protection group. This adjustment can be made in response to failures within the protection group or notifications from a high availability agent monitoring entities within a specific pod. The dynamic adjustment of active pods helps ensure the high availability of the PON.
The protection groups in the broadband network architecture provide services for different sets of end users. Membership in each set of end users can be based on limiting the failure domain of the end users, the tier of service for the PON, or a set of obligated services. This allows for tailored service provision and efficient management of the network.
Additionally, the patent describes a method for dynamically adjusting the active pods within a protection group. This method involves selecting a particular service group from a plurality of service groups serviced by the broadband network architecture and upgrading the software associated with supporting that specific service group without affecting the remainder of the service groups.
Overall, this granted patent presents a technology that ensures the high availability of a Passive Optical Network through dynamic adjustment of active pods within protection groups. The technology allows for tailored service provision and efficient management of the network, enhancing the reliability and performance of the PON.
