Extending data over cable service interface specification (DOCSIS) provisioning of ethernet passive optical network (EPON) (DPoE) to EPON over coax (EPoC) multicast key management
Disclosed herein are mechanisms to support the management of multicast keys for a multicast group comprising one or more optical line terminals (OLTs), one or more fiber to coax units (FCUs), and a plurality of coax network units (CNUs). The disclosed embodiments may support the management of multicast keys over optical and coaxial networks. In some embodiments, an FCU may facilitate communication of operations, administration and maintenance (OAM) messages containing multicast keys from one or more OLTs to one or more CNUs (typically a plurality of CNUs). Some embodiments may employ one multicast key over both the optical network and coaxial network. Other embodiments may employ an optical domain multicast key over the optical network and an electrical domain multicast key over the coaxial network. Embodiments may comprise adding a first CNU to a multicast group as well as adding subsequent CNUs to the multicast group.
