Residential CORD (R-CORD) includes services that leverage wireline access technologies like GPON, G.Fast, 10GPON, and DOCSIS. The initial release includes a disaggregated and virtualized OLT device for GPON, called vOLT. R-CORD also includes a virtual Subscriber Gateway (vSG) and leverages a core networking service - virtual Router (vRouter); the former is implemented by a container that is bound to each subscriber and the latter is an ONOS control application. Design notes for each can be found here:
