摘要： One embodiment of the present invention provides a system that facilitates dynamic allocation of upstream bandwidth in a passive optical network which includes a central node and at least one remote node. Each remote node is coupled to at least one logical entity, which corresponds to a device or a user, that transmits upstream data to the central node and receives downstream data from the central node. The central node is coupled to an external network outside of the passive optical network through a shared out-going uplink.

摘要： One embodiment of the present invention provides a system that facilitates dynamic allocation of upstream bandwidth in a passive optical network which includes a central node and at least one remote node. Each remote node is coupled to at least one logical entity and includes a number of queues, each of which is associated with a logical entity and stores upstream data from the logical entity. The central node is coupled to an external network through a shared out-going uplink. During operation, the system receives a request from a remote node for a grant to transmit upstream data from a logical entity, wherein the request reports the state of a queue associated with a logical entity; wherein the size of the data to be transmitted does not exceed a transmission threshold assigned to that logical entity, and wherein a logical entity may not request more than what is allowed by the corresponding transmission threshold. If the request satisfies a bandwidth allocation policy, the system issues a grant to the remote node to transmit upstream data. In response to the grant, the system receives upstream data from the remote node. Next, the system transmits the received upstream data to the out-going uplink according to a set of SLAs.

摘要： Embodiments enable an Ethernet over Coaxial (EoC) Coaxial Media Converter (CMC) that implements only a subset of the functions (e.g., MAC and PHY) of a cable modem termination system (CMTS). The CMC sits between an optical line terminal (OLT) and a plurality of cable modems (CMs) that it serves. From the network management side at the OLT, the CMC appears and can be managed like an optical network unit (ONU). From the subscriber side, the CMC provides the same connectivity functions to the CMs as a CMTS and serves to terminate coaxial connections from the CMs.

摘要： Protection switching methods, systems, and architectures are provided for hybrid Ethernet Passive Optical Network (EPON)-Ethernet Passive Optical Network Over Coaxial (EPOC) networks. Protection switching embodiments enable protection of the EPON portion and/or the EPOC portion of the hybrid network. In embodiments, protection switching may be initiated by an Optical Line Terminal (OLT), a coaxial media converter (CMC), or an optical network unit (ONU)/coaxial network unit (CNU) in the hybrid network.

摘要： Embodiments of a scalable optical network unit (ONU) architecture for multi-dwelling units (MDUs) that has a low initial cost (or first port cost) and a low maintenance cost are provided herein. The ONU architecture is scalable in that a growing number of end users can share a single drop fiber that couples the ONU to a passive optical network. The ONU architecture utilizes a multiplexer module to allow the ONU to be daisy chained with one or more additional ONUs.

摘要： Embodiments enable a network operator to use any (and a single) network management system (NMS) that it desires to manage a network having mixed fiber to the home optical network units (ONUs) and coaxial connected cable modems. For example, embodiments enable a cable company operator to use a DOCSIS (Data Over Cable Service Interface Specification) NMS (which the cable company already uses to manage its DOCSIS network) to manage such mixed network, by a simple addition of a DOCSIS Mediation Layer (DML) module between the NMS and the optical line terminal (OLT). On the other hand, embodiments enable a telephone company operator to use a standard EPON (Ethernet Passive Optical Network) OLT NMS with minor OLT and OAM (Operations, Administration, and Maintenance) protocol modifications to manage the same mixed network.
