A device for pre-emption in passive optical networks may include a first media access control (MAC) module configured to receive a first type of data traffic and transmit the first type of data traffic to a MAC merge module. The device may further include a second media access control (MAC) module configured to receive a second type of data traffic and transmit the second type of data traffic to the MAC merge module. The device may further include the MAC merge module configured to receive the first and second types of data traffic from the first and second MAC modules, respectively, and provide the first and second types of data traffic for transmission over a port. The MAC merge module may be configured to pre-empt the transmission of the first type of data traffic over the port in favor of the second type of data traffic.

Embodiments of the present invention provide a method and an apparatus for service control on an access node, where the access node is divided into at least one access node control protocol ANCP partition, and each ANCP partition corresponds to one network access server NAS. The method includes: obtaining, according to a set rule, a logical identifier of a physical object managed by an ANCP partition, where each logical identifier is used for identifying one physical object, and saving an obtained logical identifier in the ANCP partition; and obtaining, according to the logical identifier in the ANCP partition, an access topology of the physical object managed by the ANCP partition, and reporting the access topology in the ANCP partition to a corresponding NAS, so that the corresponding NAS performs service control according to a reported access topology.

The present disclosure pertains to systems and methods for Ethernet-based management of optical networks using ONT management interface (OMCI). In one exemplary embodiment, an Ethernet-based protocol, such as Active Ethernet, is used to implement an ONT management interface (OMCI) between an optical line terminal (OLT) and a plurality of ONTs of a MON. Further, virtual local area networks (VLANs) are used to separate the traffic carried by the MON. Various techniques are described that permit ONT registration and creation of VLANs for the MON without requiring the use of gigabit PON (GPON) constructs, such as traffic containers (TCONTs) and dedicated GPON encapsulation method (GEM) ports.

A MSO deploying a standard OLT, and installed with ONUs to be used by customers to whom the MSO can connect using optical fiber. For customers that cannot be reached with optical fiber, the MSO deploys a converter between the optical fiber and the coax network so that the MSO can use the same standard OLT, and use CNUs for those customers attached to the coax network.

A video content system includes a head end server module and a content-sharing server coupled to a video content network. Also included is a converged premises gateway module coupled to the video content network at a location remote from the head end server module and the content-sharing server. The converged premises gateway module includes a processor and a video content network interface coupled to the processor and the video content network and configured for communication with the head end server module over the video content network. The gateway module also includes a memory module having a predetermined storage location for content to be shared with the content-sharing server and a local area network configured at least for distribution of video content within the remote location. The system further includes an upload module configured to cause the content in the predetermined storage location to be uploaded to the content-sharing server.

A power supply unit includes a plurality of the interface ports and a plurality of power delivery units, each coupled to one of the interface ports and configured to extract power from data signals communicated over the interface ports by remote devices. A sharing circuit is coupled to each of the power delivery units for generating a power supply voltage from the power extracted from the data signals. A controller is configured to generate a communication line power loss estimate for each of the interface ports and configure the power delivery units to balance amounts of power supplied by each of the remote devices based on the communication line power loss estimates.

The disclosure discloses a Point-to-Point Protocol over Ethernet (PPPOE) configuration method for a Gigabit-Capable Passive Optical Network (GPON) system. The method comprises: an Optical Line Terminal (OLT) instructing an Optical Network Unit (ONU) to create or delete a PPPoE management object instance and associate the PPPoE management object instance with an IP host config data management object instance; and the ONU creating the PPPoE management object instance according to the creation instruction from the OLT, and turning on a PPPoE function switch in the IP host config data management object instance; or the ONU deleting the PPPoE management object instance according to the deletion instruction from the OLT, and turning of the PPPoE function switch in the IP host config data management object instance. The disclosure also discloses a GPON system. With the disclosure, the problem that the existing GPON system cannot support accessing in a manner of PPPoE dial-up is solved, and the PPPoE scenario requirements are met.

A relay switch is connected to the at least one service port and the central office interface. A processor is connected to the switch and relay switch and configured to receive a command message and in response switch into either the central office interface and provide the central office source service or switch into the service port and provide the local source service.
摘要:
A virtual converged cable access platform (CCAP) system and method for hybrid fiber CATV (HFC) cable networks. The system uses a new type of digital optical fiber node configured to receive optical fiber data packets, and reconstitute the optical data packets into RF waveforms suitable for injection into the system's CATV cable. The system replaces the legacy HFC head end with a simplified “virtual head end”. The system's virtual head end operates using a new type of virtual CCAP controller and virtual CCAP software that in turn controls high performance edge routers. Much of the intelligence of running the HFC cable system is managed by the controller software, while the edge router manages the interface between the CATV portion of the system and outside networks. The system can handle even legacy CATV RF signals by appropriate conversion operations, while reducing power and space needs, and improving operational flexibility.
