Abstract: Embodiments reduce overhead in Ethernet Passive Optical Network (EPON) networks by reducing the amount of switching among Optical Network Units (ONUs) done by the Optical Line Terminal (OLT). In one embodiment, Logical Link Identifiers (LLIDs) hosted by the same ONU are linked at the OLT such that the OLT grants same ONU LLIDs consecutively when appropriate. This reduces the optics related delay associated with switching among ONUS. At the same time, the linking of LLIDs hosted by the same ONU allows for data from multiple LLIDs to be grouped together within a single Forward Error Correction (FEC) block at the ONU, when appropriate, reducing FEC overhead.

Abstract: An optical line terminal (OLT) system for a passive optical network (PON) may include a processor, an OLT Medium Access Control (MAC) device communicatively coupled to PON ports, and a switch device communicatively coupled to the OLT MAC device via an Ethernet interface. The processor may map logical identifiers of each PON port to tunnel identifiers, where each tunnel identifier is indicative of a logical identifier and its corresponding PON port. The OLT MAC device may receive upstream data items that include logical identifiers over the PON ports. The OLT MAC device may replace the logical identifier of each upstream data item with the tunnel identifier that is mapped to the logical identifier and the PON port over which the upstream data item was received. The OLT MAC device may transmit, over the Ethernet interface to the switch device, the upstream data items including the tunnel identifiers.

Abstract: A method and system for channelizing a Passive Optical Network (PON) Media Access Controller (MAC) includes increasing a clock rate of each of one or more PON MAC(s) to create communication lanes each comprising a plurality of N channels. The PONs are channelized according to NX, where N equals a number of ports supported by the MAC and X equals a designated operating PON MAC clocking rate allowing for leveraging of existing Passive Optical Network (PON) infrastructures to provide a more power efficient and physically smaller MAC layer for OLTs.

Abstract translation: 无源光网络（PON）媒体接入控制器（MAC）的信道化方法和系统包括增加一个或多个PON MAC中的每一个的时钟速率，以创建每个包括多个N个信道的通信通道。 PON根据NX进行信道化，其中N等于MAC支持的端口数量，X等于指定的操作PON MAC时钟速率，允许利用现有的被动光网络（PON）基础设施提供更高的功率效率和更小的物理 OLT的MAC层。

Abstract: A system and method for Service Interoperability in Ethernet Passive Optical Network (SIEPON) energy saving statistics. Energy saving statistics can be collected from a plurality of subordinate nodes in a point-to-multipoint network through a mechanism that aggregates energy saving statistics as those energy saving statistics are reported upstream. Such aggregation of energy saving statistics can be advantageous in that the aggregated energy saving information can appear uncorrelated to individual subordinate nodes. Privacy concerns are thereby addressed.

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.
