Abstract
In one example, the present disclosure describes a device, computer-readable medium, and method for restoring local access elements in a software defined network (SDN) following service outages. For instance, in one example, a method includes retrieving, by a software defined networking local access element connected to a customer premises, configuration data and customer provisioning data from equipment located at the customer premises and initializing the software defined networking local access element with the configuration data and customer provisioning data to provide service to the customer premises.
Claims15
A method, comprising:
- sending, by a software defined networking local access element connected to a customer premises, configuration data and customer provisioning data to equipment located at the customer premises;
- subsequent to the sending, attempting to restore, by the software defined networking local access element, a connection between the software defined networking local access element and a software defined networking controller in a core network;
- failing to restore, by the software defined networking local access element, the connection between the software defined networking local access element and the software defined networking controller;
- subsequent to the failing to restore, retrieving, by the software defined networking local access element, the configuration data and customer provisioning data from the equipment located at the customer premises;
- and
- initializing, by the software defined networking local access element, the software defined networking local access element with the configuration data and customer provisioning data to provide a service to the customer premises.
A non-transitory computer-readable medium storing instructions which, when executed by a processor of a software defined networking local access element, cause the processor to perform operations, the operations comprising:
- sending configuration data and customer provisioning data to equipment located at a customer premises;
- subsequent to the sending, attempting to restore a connection between the software defined networking local access element and a software defined networking controller in a core network;
- failing to restore the connection between the software defined networking local access element and the software defined networking controller;
- subsequent to the failing to restore, retrieving the configuration data and customer provisioning data for the software defined networking local access element from the equipment located at the customer premises;
- and
- initializing the software defined networking local access element with the configuration data and customer provisioning data to provide a service to the customer premises.
A software defined networking local access element, comprising:
- a processor;
- and
- a computer-readable medium storing instructions which, when executed by the processor, cause the processor to perform operations, the operations comprising:
- sending configuration data and customer provisioning data to equipment located at a customer premises;
- subsequent to the sending, attempting to restore a connection between the software defined networking local access element and a software defined networking controller in a core network;
- failing to restore the connection between the software defined networking local access element and the software defined networking controller;
- subsequent to the failing to restore, retrieving the configuration data and customer provisioning data for the software defined networking local access element from the equipment located at the customer premises;
- and
- initializing the software defined networking local access element with the configuration data and customer provisioning data to provide a service to the customer premises.
