    摘要： A multi-source data multiplexing system that accepts information packets from a plurality of signal sources, evaluates the relative efficiencies of data transmission, and transmits the information packets in provided grant regions for maximum efficiency. The multi-source data multiplexing system may accept any form of information packet from any form of signal source. The system receives a grant region, typically comprising a transmission time on a data channel, and inserts a information packet into the grant region. The actual information packet placed in the grant region may be one other than the packet for which the grant region was intended. Further, the multi-source data multiplexing system may fragment an information packet and transmit only a portion of the information packet in the grant region. Alternately, the multi-source data multiplexing system may concatenate multiple information packets, or information packet fragments, from any combination of signal sources and transmit the concatenated result in the grant region. As long as any signal source is active, the composite flow of information packets remains active, and the composite flow then serves as the primary mechanism for requesting and transmitting additional bandwidth on the network.

    摘要： A system, method, and computer program product for synchronizing time between a centralized controller device and at least one subscriber device on a fiber access network. The control layer of a network device is expanded, and additional messaging control is added via the transmission of data frames. The expansion prevents reliance on a physical layer signal. The time synchronization also allows a time stamp to be incorporated into a message. Thus, bandwidth is not wasted by simply transmitting a time stamp by itself. In an embodiment, the centralized controller device measures the time difference between the time at which a particular ranging request is transmitted and the time at which the particular ranging request is received. The time difference represents the time adjustment value for the particular subscriber device and allows the device to synchronize its time with that of the centralized controller device.

    摘要： An optical line terminal (OLT) monitors and controls communications with a plurality of optical nodes (ONs), such as optical network units (ONUs) and/or optical network terminators (ONTs), within a passive optical network (PON), such as, but not exclusively, an Ethernet-based passive optical node (EPON). A tagging mechanism is implemented to identify an origin ON that introduces a frame into the PON segment linking the origin ON with the OLT. The origin ON produces a PON tag to associate its identifier (ON_ID) to the frame. The PON tag facilitates filtering and forwarding operations, and enables the physical layer interface (PHY) to the PON segment to emulate a point-to-point and/or shared communications link. The PON tag allows a MAC control layer to create virtual ports to traffic incoming and outgoing optical signals, and supply the virtual ports to a forwarding entity for frame filtering and forwarding. The PON tag also allows an OLT and ON to track the origination and/or destination of a frame within the PON segment, and accept or reject the frame based on the contents of the PON tag.
