    摘要: Provided is a network system including a start device and multiple end devices. A point-to-point (P-to-P) logical path is set to be used for unicast communication between the start device and each of the end devices. A first point-to-multipoint (P-to-M) logical path and a second P-to-M logical path are set to be used for multicast communication from the start device to the multiple end devices. The start device transmits data over the first P-to-M logical path. When one of the end devices detects a defect along the first P-to-M logical path, the end device that has detected the defect transmits a switch request over the P-to-P logical path set between this end device and the start device. The start device receives the switch request and transmits data over the second P-to-M logical path.

    摘要: A packet communication apparatus includes a frame buffer of a linked list method and holds chain information and buffer size information, for structuring a linked list buffer for each user flow, in two areas consisting of an operation area and an update area. While usually in service, the buffer is structured by using the chain information in the operation area and the buffer size information in the same area such that the frame is read/written in the frame buffer. When the chain information in the update area and the buffer size information in the same area have been changed, a queue size is changed by reflecting the updated chain information and the updater buffer size information into the operation area, when both the read pointer and the write pointer respectively have gone around the buffer, or when there is no frame stored in the buffer.

    摘要: Disclosed herewith is a packet transfer apparatus that carries out 1+1 protection switching for traffics to be received variably in both length and cycle. The apparatus enables flows to be multiplexed and the link usage efficiency to be improved without generating any buffer overflow errors. The data transfer apparatus, upon receiving the third sequentially numbered data from the first communication route before receiving the preceding second sequentially numbered data, stores the received third data in a buffer. And upon receiving the second sequentially numbered data from the second communication route, the apparatus sends the second and third data sequentially. Then, upon receiving the third sequentially numbered data from the second communication route before receiving the second sequentially numbered data, the apparatus sends the third data when a predetermined waiting time expires.

    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.
