摘要： In a switching node, high-speed and advanced service protocol processing function is achieved by utilizing an external control server without affecting performance of conventional service protocol processing. Specifically, a forwarding engine has PCI express and an LAN interface. Depending on a type of an input packet, destination of the packet is switched to the PCI express side for conventional network service and to the LAN interface side for extended network service that cooperates with the external control server. A CPU having the PCI express and the LAN interface is provided ahead of the LAN interface. The CPU performs communication of service inquiry with the external control server at high speed via the LAN interface. After response from the control server is obtained, setting of the forwarding engine is performed through the PCI express.

摘要： In a network system in which a switch forwarding packets and a control server determining route information are separated, it is desired to achieve a redundancy of the control channel by an out-of-band control channel and an in-band control channel, when the switch receives a control message regarding the flow entry registration and the like based on the route information from the control server. Specifically, the separated switch and control server are connected by a control channel for sending and receiving the control message. The switch is not only connected to a control server via an out-of-band control channel by a route dedicated to the control message, but also connected to another control server via an in-band control channel by a route which is common with a normal data communication for determining the route information, to achieve a redundancy of the control channel.

摘要： A packet forwarding device that maintains packet sequence before and after packet forwarding is provided. A cache stores forwarding information. A forwarding unit refers to the forwarding information to attempt to determine a forwarding destination of a received packet, sends the packet to a control unit irrespective of whether or not the forwarding destination of the packet could be determined, and in cases in which the forwarding destination of the packet could not be determined, requests the control unit to determine the forwarding destination of the packet. The control unit receives the packet from the forwarding unit, and in cases in which the control unit has been requested by the forwarding unit to determine the forwarding destination of the packet, determines the forwarding destination of the packet, sends the packet to the forwarding destination and stores the forwarding destination as forwarding information in the cache, and in other cases, sends the packet to the forwarding destination determined by the forwarding unit.
摘要翻译：提供了在分组转发之前和之后维护分组序列的分组转发设备。缓存存储转发信息。转发单元参考转发信息，尝试确定接收到的分组的转发目的地，将分组发送到控制单元，而不管可否确定分组的转发目的地，并且在转发目的地不能确定分组的请求，请求控制单元确定分组的转发目的地。控制单元从转发单元接收分组，并且在转发单元请求了控制单元以确定分组的转发目的地的情况下，确定分组的转发目的地，将分组发送到转发目的地并将转发目的地作为转发信息存储在高速缓存中，在其他情况下，将分组发送到由转发单元确定的转发目的地。
