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.
摘要翻译：这里公开了一种PON系统和带宽控制方法，其能够在连接到OLT的网关（GW）中发生拥塞时有效地控制在PON部分中使用上行带宽的拥塞。当从GW接收到指示发生拥塞发生拥塞的拥塞发生通知时，通过无线光网络（PON）连接到多个ONU并通过通信线路连接到网关（GW），识别ONU的标识符正在使用具有拥塞输出端口号的GW输出线，并且以正常模式移动PON部分的带宽控制，以将每个ONU的带宽正常分配给带宽抑制模式中的带宽，以分配拥塞时间允许带宽小于根据其传输队列长度具有所识别的ONU标识符的ONU的当前带宽和对于每个其他ONU的带宽。

摘要： A link aggregation function and maintenance function by MPLS OAM. Identical entry information is stored in plural circuits IF which perform a LA setting. In this way, multiplexing to the same LSP is possible even with different IF. The first network IF is assumed to be OAM ACT, and the second network IF is set to OAM SBY (SBY). OAM frame insertion is performed only by an OAM ACT port. In this way, in an opposite MPLS transmission apparatus, it is possible to prevent CV frame reception above a specified number of frames. Further, a switch forwarding table is set to forward frames from the network side to the first network IF of OAM ACT. The second network IF which was set to OAM SBY does not perform fault detection by CV reception. In this way, incorrect detection of faults due to non-reception of OAM can be prevented.
摘要翻译： MPLS OAM的链路聚合功能和维护功能。相同条目信息存储在执行LA设置的多个电路IF中。以这种方式，即使使用不同的IF，也可以复用到相同的LSP。第一个网络IF被假定为OAM ACT，第二个网络IF设置为OAM SBY（SBY）。 OAM帧插入仅由OAM ACT端口执行。以这种方式，在相反的MPLS传输装置中，可以防止CV帧接收高于指定帧数。此外，设置交换机转发表将帧从网络侧转发到OAM ACT的第一网络IF。设置为OAM SBY的第二个网络IF不通过CV接收执行故障检测。以这种方式，可以防止由于不接收OAM导致的故障的错误检测。

摘要： A packet transfer apparatus connects two networks of different protocols. The packet transfer apparatus, connected to a first communication network and a second communication network, performs the steps of: storing first destination correspondence information; receiving a packet of the first communication protocol; based on the first destination correspondence information, determining destination information of a packet of the second communication protocol corresponding to destination information of the received packet of the first communication protocol; generating the header of the packet of the second communication protocol, based on the determined destination information of the packet of the second communication protocol; converting the received one or more packets of the first communication protocol into one or more packets of the third communication protocol; and adding the generated header of the packet of the second communication protocol to the packets of the third communication protocol.
