US Patent 10318335 Self-managed virtual networks and services

Systems and methods described herein include high-availability layers for virtualized systems and services. Virtual network elements include an infrastructure layer that automatically detects and repairs failures in hardware and an operating system for one of the virtual network elements; a virtualization layer that automatically detects and repairs failures in a hypervisor executing on the hardware and the operating system; a virtual machine layer that automatically detects and repairs failures in virtual machines managed by the hypervisor; a virtual network function layer that automatically detects and repairs failures in virtual network functions executed on the virtual machines; and a connection layer that automatically detects and repairs failures in connections between the virtual network elements. Each layer includes a fix agent, which uses artificial intelligence rules to automatically provide an estimated fix time interval for a local failure and to repair the local failure, and a fault management agent, which diagnoses failures within the corresponding layer.
