VOLTHA (Virtual OLT Hardware Abstraction is an open source project to create a hardware abstraction for broadband access equipment. It supports the principle of multi-vendor, disaggregated, “any broadband access as a service” for the Telco Central Office.
Key concepts in VOLTHA:
Network as a Switch: It makes a set of connected access network devices to look like a SDN programmable switch.
Evolution to virtualization: it can work with a variety of access network technologies and devices
Unified OAM abstraction: it provides unified, vendor- and technology agnostic handling of device management tasks, such as service lifecycle, device lifecycle (including discovery, upgrade), system monitoring, alarms, troubleshooting, security, etc.
Cloud/DevOps bridge to modernization: it does all above while using a microservices architecture running on top of Docker and/or Kubernetes.
