摘要:
A visualization device is communicable with one or a plurality of host servers for hosting a virtual system, and includes an information acquisition unit for collecting configuration information on the virtual system and the host server, a storage unit for storing the configuration information therein, and a drawing unit for expressing a virtual machine and a virtual network configuring the virtual system with different axes based on the configuration information stored in the storage unit, expressing a connection relationship between a virtual machine and a virtual network by linking the lines extending from the respective axes, and grouping virtual machines in units of server on which the virtual machines operate thereby to generate drawing information for expressing the configuration of the virtual system and the host server.
摘要:
A communication system, includes: a node that requests a processing rule for processing a packet; and a control apparatus that notifies the node of the processing rule in response to the request. The control apparatus, upon being notified of change of a connection relationship between a communication apparatus to which a packet is addressed and the node, determines a forwarding path for a packet addressed to the communication apparatus and notifies the node of a processing rule for realizing the forwarding path.
摘要:
Authentication apparatus authenticates user using host connected to forwarding node. Policy management apparatus holds access control policy for identifying host under access control using identifier of forwarding node or identifier of user, and links identifier of host under access control and identifier of forwarding node to which host is connected, or identifier of host under access control and identifier of user using host. Forwarding node transmits to policy management apparatus identifier of host connected to own forwarding node and identifier of own forwarding node. Authentication apparatus transmits to policy management apparatus identifier of host connected to forwarding node and identifier of user. Policy management apparatus refers to access control policy and, if host connected to forwarding node is under access control, notifies content of access control to control apparatus as access control list. Control apparatus generates processing rule in accordance with access control list and sets generated processing rule in forwarding nodes.

Authentication apparatus authenticates user using host connected to forwarding node. Policy management apparatus holds access control policy for identifying host under access control using identifier of forwarding node or identifier of user, and links identifier of host under access control and identifier of forwarding node to which host is connected, or identifier of host under access control and identifier of user using host. Forwarding node transmits to policy management apparatus identifier of host connected to own forwarding node and identifier of own forwarding node. Authentication apparatus transmits to policy management apparatus identifier of host connected to forwarding node and identifier of user. Policy management apparatus refers to access control policy and, if host connected to forwarding node is under access control, notifies content of access control to control apparatus as access control list. Control apparatus generates processing rule in accordance with access control list and sets generated processing rule in forwarding nodes.
摘要:
A communication system includes: a forwarding node(s) in which a first packet handling operation(s) for processing incoming packets is set and which processes packets in accordance with the packet handling operation(s); a first control apparatus setting the first packet handling operation(s) in the forwarding node(s); a flow control node(s) arranged upstream of the forwarding node(s); and a second control apparatus setting a second packet handling operation(s) in the flow control node(s). The flow control node(s) intercepts forwarding of packets that do not satisfy a predetermined condition(s) to the forwarding node(s) in accordance with the second packet handling operation(s).

摘要:
A communication terminal comprises: first means that communicates with a network system that includes a forwarding apparatus forwarding a packet and a control apparatus informing the forwarding apparatus of a processing rule prescribing a packet processing method; second means that determines a processing operation to be executed by the network system from among packet processing operations to be executed by the communication terminal; and third means that informs the forwarding apparatus of a processing rule corresponding to the determined packet processing operation.
