Abstract: 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.

Abstract: A system and method for bandwidth-delay-product (BDP) decoupler. A BDP decoupler mechanism is provided that enables an intermediate network device to facilitate an efficient transfer of traffic from a server to a client. In one embodiment, the intermediate network device can be configured to buffer received data and control the transmission of the buffered data to the client device based on acknowledgment messaging received by the intermediate network device from the client device.

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 of the present disclosure provide efficient solutions for detecting and transmitting heartbeat frames at an optical line terminal (OLT) of an Ethernet passive optical network (EPON). The processing burden of a host CPU is reduced by shifting some of the processing responsibilities of the host CPU to an embedded CPU. An OAM capture FIFO buffer stores frames for later processing by the embedded CPU, and fields of an OAM vector register are changed whenever a heartbeat frame is detected for an LLID. Embedded CPU polls the OAM vector at a predetermined rate sufficient to maintain link status, so heartbeat messages are not missed even when the OAM capture FIFO buffer overflows. Additionally, an OAM generation buffer efficiently creates new heartbeat messages to be sent to ONUs for each supported LLID by modifying previously transmitted OAM frames with new information specific to the LLIDs.

Abstract translation: 本公开的实施例提供了用于在以太网无源光网络（EPON）的光线路终端（OLT）处检测和发送心跳帧的有效解决方案。 主机CPU的处理负担通过将主机CPU的一些处理职责转移到嵌入式CPU来减少。 OAM捕获FIFO缓冲器存储帧以供嵌入式CPU稍后处理，并且每当为LLID检测到心跳帧时，OAM向量寄存器的字段将被更改。 嵌入式CPU以足以维持链路状态的预定速率轮询OAM向量，因此即使OAM捕获FIFO缓冲区溢出也不会丢失心跳消息。 另外，OAM生成缓冲器通过使用特定于LLID的新信息修改先前发送的OAM帧，有效地创建新的心跳消息，以将其发送到每个支持的LLID的ONU。
