摘要： A configuration of a communication system that is able to effect packet forwarding in accordance with an intended forwarding path even in an environment where a node represented by a Layer-2 switch (L2SW) and a node represented by an OpenFlow switch exist together, is provided. The communication system includes a first node, such as a Layer-2 switch, a plurality of second nodes, equivalent to the OpenFlow switches, and a controller. The controller causes the first node to receive a destination learning packet from one of the second nodes lying on the downstream side of the first node on a preset packet forwarding path. The destination learning packet has a node lying on the downstream side of the first node as a transmission source, so that the controller causes the first node to perform a packet forwarding operation in accordance with the packet forwarding path.

摘要： A routing device includes a memory for storing routing entries in a routing table and a cache memory for storing some of routing entries present in the memory together with a mask length of a destination address as a cache entry. A high-speed retrieval section retrieves the cache entry corresponding to the destination address by referencing the cache memory based on the destination address of an input packet. An ordinary retrieval section retrieves the routing entry corresponding to the destination address by referencing the memory. A processing section writes the cache entry into the cache memory based on the routing entry retrieved by the ordinary retrieval section. The router device enables routing without using a routing entry that should not be used in the routing originally even when part of the routing table is cached.
摘要翻译：路由设备包括用于存储路由表中的路由条目的存储器和用于存储存在于存储器中的一些路由条目以及目的地地址的掩码长度作为高速缓存条目的高速缓存存储器。高速检索部分通过基于输入分组的目的地地址引用高速缓冲存储器来检索对应于目的地址的高速缓存条目。普通检索部分通过引用存储器检索与目的地地址对应的路由条目。处理部分基于由普通检索部分检索到的路由条目将高速缓存条目写入高速缓冲存储器。路由器设备启用路由，而不使用最初不应该在路由中使用的路由条目，即使部分路由表被缓存。

摘要： A communication system includes a plurality of first nodes that, in accordance with processing rules (packet handling operations) prescribing processing contents for a packet belonging to a pre-set flow, processes a packet received, which matches to the processing rules, and a second node that forwards the received packet via its ports without referencing the processing rules. The communication system also includes a control apparatus that sets, for the first nodes situated on a forwarding path for the packet belonging to the pre-set flow, processing rules to forward the packet belonging to the pre-set flow to each next hop. The control apparatus also sets, for the first node not situated on the forwarding path, processing rules to instruct dropping the packet that is forwarded from the second node and that is deviated from the forwarding path.
