Abstract: A common control unit (141A) acquires a configuration input request to a communication device accommodating a user using a network. An individual control unit (142A) identifies a variable group necessary for a command to execute the configuration input based on request content of the configuration input received by the common control unit (141A) and a type of communication device and transmits the identified variable group to the common control unit (141A). A command execution unit (143A) acquires the variable group identified by the individual control unit (141A) from the common control unit (141A), generates a command based on the acquired variable group, and executes the generated command.

Abstract: A packet communication quality measurement method and system in which two quality measurement devices connected via a packet communication network exchange a probe packet via the network. The packet communication quality is calculated based on the transmission/reception status of the probe packet. Probe packets are intermittently transmitted from one quality measurement device to another via the network at a predetermined interval, and received by the other device. The communication quality of each probe packet is calculated based on the transmission/reception status of the probe packet. The communication quality of user packets is estimated by weighting the communication quality of probe packets in accordance with the number of user packets flowing in a desired measurement direction along the path which connects the quality measurement devices at an interval between transmission of a previous probe packet and transmission of the probe packets.
