    摘要： Disclosed herewith is a PON system and a bandwidth controlling method capable of controlling congestion with use of an upstream bandwidth in a PON section efficiently when congestion occurs in a gateway (GW) connected to an OLT. An OLT connected to a plurality of ONUs through a passive optical network (PON) and to a gateway (GW) through a communication line, when receiving a congestion occurrence notice indicating a congestion occurred output number from a GW, identifies the identifier of the ONU that is using a GW output line having the congestion output port number and shifts the bandwidth controlling of the PON section in a normal mode for allocating a bandwidth to each ONU normally to that in a bandwidth suppression mode for allocating a congestion time allowable bandwidth that is less than the current bandwidth to the ONU having the identified ONU identifier and a bandwidth to each of other ONUs according to its transmission queue length.

    摘要： The invention realizes defect indication on a multipoint logical path and switching of the logical path using a transfer protocol of configuring a logical path in a ring network. A working path and a backup path are set up where each transmits a frame from a transmitting end node to multicast receiving end nodes, forwards the frame to the transmitting end node and terminates it at the transmitting end node after going around the ring. Any node detecting a defect transmits a forward defect indication frame to a multipoint logical path in which the defect occurs. The transmitting end node receiving the forward defect indication frame halts the use of the notified multipoint logical path, and transmits a frame in another path where the forward defect indication frame is not received. When received from both multipoint logical paths, the transmitting end node copies the frame and forwards them to both paths.

    摘要： The invention realizes defect indication on a multipoint logical path and switching of the logical path when the multipoint logical path is configured using a transfer protocol of configuring a logical path, typified by MPLS etc., in a ring network. Two routes of the multipoint logical paths, a working path and a backup path, are set up. Each of them not only transmits a frame transmitted from a transmitting end node to multicast receiving end nodes but also forwards the frame to the transmitting end node and terminates it also at the transmitting end node after making it go around the ring. Any node that detects a defect transmits a forward defect indication frame to a multipoint logical path in which the defect occurs. The transmitting end node having received the forward defect indication frame halts the use of the notified multipoint logical path, and transmits a frame in another path in which the forward defect indication frame is not received within a fixed time period. Moreover, when the forward defect indication frame is received from the both multipoint logical paths, the transmitting end node copies the frame and forwards them to the both multipoint logical paths.
