摘要： A communication equipment notifies a server equipment of a communication port to which a communication cable is connected. If another communication port as a connection partner of the notified communication port is not yet connected to the communication cable, the server equipment transmits a first notification instruction to another communication equipment having the said another communication port. The said another communication equipment indicates, in a viewable manner, a communication port corresponding to the first notification instruction as a communication port to which the communication cable is required to be connected.

摘要： Provided is an MRA (multi-root aware) PCI express switch accommodating a plurality of root complexes. The MRA PCI express switch includes: a setting register storing necessary information to set a PCI tree based on a switch connection topology and a physical connection state; and a virtual switch bridge controller storing necessary information to establish a virtual PCI tree, irrespective of a status of the setting register. The root complexes can be booted based on the information in the virtual switch bridge controller.

摘要： A TCP 2003 is terminated in an intermediate driver 2006 within a gateway device 20, a TCP 3003 is terminated in an intermediate driver 3006 within a gateway device 30, and a frame is transferred between the intermediate drivers with a method not causing a congestion control such as a UDP. Besides, an SSL session is constructed between an SSL 2002 and an SSL 3002, and upon completing construction of the session, a public key and a secret key are sent by means of an Ethernet frame from a processing speed acceleration engine control to a processing speed acceleration engine. Thus, the gateway device transfers the frame not through a CPU but by employing the processing speed acceleration engine within an NIC in later communication between a terminal 21 and a server 31.

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： In a switching node, a low-load and high-speed control is performed without using a CPU and a network protocol, such as TCP/IP, which have been conventionally used for control from a remote control server, to realize a high-end and high-speed network service by making use of the high-speed CPU processing capacity of a remote control server. Specifically, a forwarding engine incorporates a PCI express, a PCI express LAN conversion bridge and a circuit which can access to a local bus control interface from the PCI express on the switching node. The external control server incorporates an extended network service interface driver for managing a plurality of switching nodes.
