Together, SDN-Enabled Broadband Access (SEBA™) Reference Design and VIrtual OLT Hardware Abstraction (VOLTHA™) open source stack comprise ONF’s broadband access solution for carrier networks. SEBA is a Reference Design (RD) - an architecture that supports a multitude of virtualized access technologies at the edge of the carrier network, including PON, G-PON, G.Fast, and eventually DOCSIS and more. SEBA supports both residential access and wireless backhaul and is optimized such that traffic can run ‘fastpath’ straight through to the backbone without requiring VNF processing on a server. It's built with Kubernetes, high speed, and operationalized with FCAPS and OSS Integration. It serves as the foundational architecture for VOLTHA.
VOLTHA is an open source project for PON broadband access equipment, supporting the principle of multi-vendor, disaggregated, “any broadband access as a service” for the Central Office. VOLTHA is an open source project for PON broadband access equipment, supporting the principle of multi-vendor, disaggregated, “any broadband access as a service” for the Central Office. VOLTHA provides isolation between an abstract (vendor agnostic) PON management system, and a set of vendor-specific and white-box PON hardware devices. On its north-bound interface, VOLTHA provides a set of abstract APIs that enable the PON network to appear as a programmable Ethernet switch to an SDN controller. On its south-bound side, VOLTHA communicates with PON hardware devices using vendor-specific protocols through OLT and ONU adapters.
SEBA/VOLTHA is being used by Leading Carriers
