Abstract
A management server that includes a signal control unit for controlling a signal for a packet for measuring communication quality, and a signal communication quality measurement unit that measures communication quality of a signal based on a result of signal control by the signal control unit; and a communication quality measurement device includes a payload control unit for controlling payload of packets for communication quality measurement and a payload communication quality measurement unit that measures communication quality of payload based on a result of payload control by payload control unit.
Claims13
A communication quality measurement system that manages communication quality between opposing communication quality measurement devices based on a result of transmitting and receiving packets for measuring communication quality between the opposing communication quality measurement devices installed at plural measurement bases in a communication network, comprising:
- a management server that includes a signal control unit for controlling a signal for one or more of said packets for measuring communication quality, and a signal communication quality measurement unit that measures communication quality of a signal based on a result of signal control by said signal control unit;
- and
- at least one of the communication quality measurement devices includes a payload control unit for controlling payload of said packets for communication quality measurement and a payload communication quality measurement unit that measures communication quality of payload based on a result of payload control by said payload control unit.
A communication quality measurement device installed in a measurement base in a network so as to be able to communicate with a management server and measure communication quality with an opposing communication quality measurement device based on a result of transmitting and receiving packets for measuring communication quality, comprising:
- a payload control unit that controls payload of said packets for measuring communication quality;
- and
- a payload communication quality measurement unit that measures communication quality of payload based on a result of payload control by said payload control unit.
A communication quality measurement agent implemented in a communication device installed at a measurement base in a network so as to be able to communicate with a management server and to cause a control device of said communication device to measure communication quality with an opposing communication device or communication quality measurement device based on a result of transmitting and receiving packets for measuring communication quality with the opposing communication device or communication quality measurement device;
- wherein, said agent causing said control device to execute:
- a payload control procedure that controls payload of said packets for measuring communication quality;
- and
- a payload communication quality measurement procedure that measures communication quality of payload based on a result of payload control by said payload control procedure.
A management server installed in a measurement base in a network that manages a communication quality measurement device for measuring communication quality between opposing communication quality measurement devices based on a result of transmitting and receiving packets for measuring communication quality between the opposing communication quality measurement devices comprising:
- a signal control unit that controls a signal for said packets for measuring communication quality, and
- a signal communication quality measurement unit that measures communication quality of a signal based on the result of signal control by said signal control unit.
A communication quality measurement method in which a management server manages communication quality between opposing communication quality measurement devices based on a result of transmitting and receiving packets for measuring communication quality between the opposing communication quality measurement devices installed at plural measurement bases in a communication network, comprising:
- said management server
- controlling a signal for measuring communication quality, and transmitting the signal to one of the communication quality measurement devices in response to a notification of starting communication quality measurement from said communication quality measurement device;
- and
- measuring communication quality of the signal based on a result of signal control by said signal controlling;
- and
- said communication quality measurement device
- transmitting a notification of starting communication quality measurement to said management server;
- controlling payload of said packets for measuring communication quality;
- measuring communication quality of payload based on a result of payload control by said payload controlling;
- and
- relaying said signal received from the management server to another of said opposing communication quality measurement devices and relaying a response result to the signal received from the other of said opposing communication quality measurement devices to the management server.
