摘要： In the case of a system where a communication device is remote-controlled from a control server, depending on timing when an entry is written into a forwarding table of the communication device from the control server, there is a possibility that a loop and discard of the traffic occur. Therefore, for registration, rewriting and deletion of the entry of the forwarding table which are performed on the communication device 102 by the control server 101; the communication device 102 verifies contents of control instructions from the control server 101; the communication device 102 holds the result of this verification; the control server 101 acquires the result of the verification; the control server 101 judges whether or not a series of controls can be executed based on the results of the verification from the plurality of communication devices 102; and then the control server 101 invokes the execution at the plurality of communication devices 102.

摘要： A VPN connection method and a communication system are provided, each which can omit the setting of a firewall and the installation of a relay server and can establish communications from the outside of a firewall to the inside thereof. The internal network 2 is connected to the external network 1 via the firewall 13. The internal network 2 enables communications by an e-mail from the external network 1 (outside the firewall) to the mail server 21 in the internal network 2 (inside the firewall) or communications by telephone or radio, which is not via the firewall 3. The feature of the firewall 3 is utilized that access from the outside to the inside of the firewall through VPN connection is very difficult but the access in the reverse stream can be simply performed. Using the mail server, telephone line or radio line, the internal network 2 receives an e-mail, which requires for VPN connection from the external network 1, or control information through the telephone line. Thus, the internal network 2 sends callback for VPN connection to the e-mail transmission source. As a result, the callback allows the external network 1 to pass through the firewall 3.

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： A trouble analysis apparatus is provided which includes: a system topology storing portion; an error detection information receiving portion which collects error detection information; and a trouble source determination portion which, based on both the error detection information collected by the error detection information receiving portion and system topology information stored in the system topology information storing portion, determines a trouble source functional element that is presumed as a functional element which is a source of a system trouble. Links included in the system topology information have information indicating spreading directions of error operations between the functional elements when trouble occurs. When the trouble source detection portion receives the error detection information with regard to multiple error functional elements, the trouble source determination portion sequentially selects one of the multiple error functional elements. The trouble source detection portion determines whether or not directions from the selected error functional element to other error functional elements conform to the spreading directions included in the system topology information. The trouble source determination portion determines the selected error functional element as the trouble source functional element when the spreading directions are conformable.
