摘要： PROBLEM TO BE SOLVED: To provide a method for dynamically managing forwarding information with an aggregation on the basis of routing information by sharing, in real time, the routing information collected from nodes in each of all the nodes of a distributed structure router. SOLUTION: The routing information collected from all the nodes of the distributed structure router is shared in real time in each of the nodes and the routing information is utilized to dynamically manage the forwarding information, thereby omitting a packet forwarding process between nodes for sharing the routing information. Besides, the routing information is selectively updated in a forwarding table to efficiently manage forwarding tables by nodes. Further, a binary aggregation tree is utilized to manage the forwarding information of each node and a level of a virtual node for aggregating node information corresponding to the routing information is variably set to reduce a size of the forwarding tables by nodes in the distributed structure router.

摘要： PROBLEM TO BE SOLVED: To prevent data from being discarded at an output port even in the case that traffic is concentrated on a specific port of a specific node and large data signals continuously flow in with respect to one output port speed in a network wherein a plurality of nodes are connected to a ring-shaped communication line.
SOLUTION: A rate measuring section 118 measures inflow excess rate information of output buffers 112 wherein output data is temporarily stored on the tributary side, per port and broadcasts the inflow excess rate information to other nodes. When receiving inflow excess rate information from another node, a band control section 119 sets a transfer rate of output data to ports of this another node on the basis of the received inflow excess rate information. Band control of data to be transmitted is performed while confirming inflow excess rates of output buffers 112, whereby a traffic volume to be discarded can be reduced.

摘要翻译：要解决的问题：为了防止在业务集中在特定节点的特定端口上的情况下在输出端口丢弃数据，并且大量数据信号相对于一个输出端口速度连续流入网络，其中多个节点连接到环形通信线路。解决方案：速率测量部分118测量输出缓冲器112的流入过剩率信息，其中输出数据临时存储在每个端口的支路侧，并将流入过量率信息广播到其他节点。当从另一个节点接收到流量超过率信息时，频带控制部分119根据所接收的流量过剩率信息，将输出数据的传送速率设置为该另一个节点的端口。在确认输出缓冲器112的流入超过率的同时执行要发送的数据的频带控制，从而可以减少要丢弃的业务量。版权所有（C）2011，JPO＆INPIT
