Abstract: A service provisioning enabled management in Service Interoperability in Ethernet Passive Optical Network (SIEPON) switching subsystem. The delivery of network services to each of a plurality of subscribers coupled to an optical network unit (ONU) can be defined individually by the service provider. The service-specific functions within the ONU can be configured based on knowledge of the levels of provisioning of network services.

Abstract: A system and method for carrying control data in a preamble. A control-data bearing preamble is defined to facilitate end-to-end labeling and control-data transport. This control-data bearing preamble provides a unified labeling scheme with minimal overhead, which facilitates greater ease in parsing. The control-data bearing preamble can be converted to/from other control/labeling schemes at the edge of the control-data bearing preamble aware portion of the network.

Abstract: Embodiments provide systems and methods for a probabilistic reporting mode, where an Optical Network Unit (ONU) sends a REPORT message only when it has data to transmit. The absence of a REPORT message from an ONU is treated by the Optical Line Terminal (OLT) as indicating absence of data to transmit at the ONU. In another aspect, embodiments include systems and methods for an unsolicited burst mode, where an ONU can be configured to transmit data in the upstream in an unsolicited manner. The unsolicited burst mode includes mechanisms to ensure that no data is lost due to potential collisions between ONUs.

Abstract: Systems and methods are provided to use of out-of-band (OOB) channels for the transport of network-synchronization signals and network control information. These OOB channels transport synchronization and control channels over low-frequency bands outside of the frequency bands used for the data channels. Locating expensive network-synchronization functions in the optical network unit (ONU) and sharing the derived synchronization signals among multiple downstream customer premises equipment (CPE) devices results in cost savings and provides a means for maintaining a continuous, end-to-end synchronization reference, even during periods when the data channels on the copper network segment are in an energy-efficiency mode (e.g., a low-power and/or sleep mode).

Abstract: In general, the 1G-EPON standard specifies its upstream waveband broadly to allow for low cost lasers to be used to transmit upstream. Often, however, the lasers actually used by many 1G-ONUs to transmit upstream only occupy a narrow waveband that does not overlap with the upstream waveband specified by the 10G-EPON standard. The present disclosure is directed to systems and methods that exploit this fact to efficiently provide for the coexistence of 10G-EPON and 1G-EPON over the same set of optical fibers in the upstream direction.

Abstract translation: 一般来说，1G-EPON标准规定了其上游波段，以允许低成本激光器用于向上游传输。 然而，通常，许多1G-ONU实际上用于上行传输的激光器仅占用与10G-EPON标准规定的上行波段不重叠的窄波段。 本公开涉及利用该事实有效地提供10G-EPON和1G-EPON在上游方向上在同一组光纤上共存的系统和方法。

Abstract: One embodiment provides a system for controlling flow rate in an EPON. The system includes an OLT, an ONUs coupled to the OLT via a passive optical splitter, a switch coupled to a port located on the ONU, and a flow-control mechanism. The ONU includes one or more queues corresponding to one or more classes of Services, and one or more ports. The switch includes a plurality of UNI ports, and the switch is configured to switch one or more upstream traffic flows belonging to the one or more classes of services from the plurality of UNI ports. The flow-control mechanism is configured to set a flow rate of an upstream traffic flow of certain class of service originated from a UNI port. The flow-control mechanism sets the flow rate based on status of an ONU queue corresponding to the class of service of the upstream traffic flow.

Abstract: A system is described that improves network function virtualization. The system facilitates an access point, such as a customer premises equipment, to utilize functionality of another access point when providing communication service to a device at a customer premises. The other access point may be a customer premises equipment at a neighboring premises. The access point may utilize the neighboring access point in case the access point is in a power saving state. Alternatively or in addition, the access point may use the other neighboring access point based on bandwidth availability, processing capability, memory capacity, or other attributes, or a combination thereof of the neighboring access point. In yet another example, the access point may utilize the neighboring access point in case of a failure in connection between the access point and a network provider.
