摘要： Provided is a network system, comprising: a plurality of network devices; a network constructed from the plurality of network devices; and a management server managing the network. The plurality of network devices include a first network device in which a filter assigned as a target of reconfiguration is set and a second network device coupled at a lower level of the first network device. The management server obtains topology of the network from the plurality of network devices; reconfigures, by referring to the obtained network topology, the filters of the first and second network device such that a range in which a packet can be forwarded through a reconfiguring filter set in the first network device is made equal to a range in which a packet can be forwarded through the filter set in the second network device; and sets the reconfigured filters into the network devices.

摘要： A network management apparatus and a network management system are provided which are capable of reducing setting workloads required when an initial setting operation of a network communication apparatus is performed, and a network structure is changed. The network management apparatus acquires information as to respective network communication apparatus which belong to the same network when an operation of the network is commenced, or when a structure of the network is changed. Then, the network management apparatus determines a concrete operating content of said network communication apparatus based upon the acquired information and an operation policy so as to set the determined operating content. Also, the network management apparatus is equipped with a GUI (Graphical User Interface) used to set a role of the network communication apparatus by a manner.

摘要： Provided is a management computer which reduces the workload of an administrator of a network in setting node when the normal network is changed to a network with redundancy. The management computer manages a plurality of nodes that constitute a network accommodating VLANs. The plurality of nodes include a first node and a second node which make a redundancy pair and which divides the network into an active path and a standby path. The management computer stores port management information showing connection relations for respective nodes and identifiers of VLANs allocated to ports of the nodes, and creates the redundancy pair by updating the port management information of the first node such that a VLAN allocated to one of ports of a connected node that is connected to the first node is allocated to one of ports of the first node that is connected to the connected node.

摘要： The invention reduces the initial setting cost, the management cost, and reconfiguration cost of QoS guarantee for network devices. A management device has a control unit and the storage unit. The control unit obtains the number of terminals contained in the network system and connection relations of the network system at the time of initial setting for QoS guarantee. A control unit stores an operation policy which an administrator inputs. The control unit creates QoS control configuration for each connection path between adjacent two network devices using the number of terminals in the network system, the connection relations, and the operation policy. And QoS control configuration is the information for controlling the QoS guarantee of network devices. And the control unit sets the QoS control configuration in the network devices.
