NEC has announced that it has developed a technology that can be estimated instantaneously the communication speed of the mobile network and the Internet, such as 3G/LTE.

It is to ensure the stability of the communication of the mobile network and the Internet, the control to match the transmission rate, and adjusting the amount of communication can be valid. However, in the method of measuring the communication speed general, there is a problem it is necessary to transfer large amounts of data, long time, a large communication load and according to the measurement.

the transfer of a small amount of data, communication speed estimation technique this time, NEC has developed, that can be estimated within one second communication speed.

Accuracy more than 80%

Mechanism is intended to be to transmit at regular intervals in order of size, the packets of the plurality of packet sizes are different, to determine the position where the reception intervals of each packet starts spreading at the receiver, and estimates the communication speed.

In NEC, it was demonstrated that the evaluation experiments using mobile network, it is possible to estimate the baud rate with an accuracy of more than 80% within one second.

The time required for the estimation, "can be estimated immediately before the service providing the communication speed of the latest possible and parameter setting of the content distribution control" and corresponds to 1/40 of the measurement process according to the data transfer generic.

Communication load is 1/180 of a conventional

Packet size to be used for the estimated tens of K bytes. Compared with the measurement general method, reduced to 1/180 the communication load "because it does not burden most network can be estimated repeatedly communication speed" (NEC).

The use of the technology developed in the NEC, makes it possible to monitor at low loads the variation of the communication speed of the terminal, "Carriers provides Web services and.

Video distribution leading to improved quality such as IP telephony services By allowed to follow the changes in communication speed and image quality of video distribution, to optimize and provide video stable uninterrupted, the size of the data to be delivered in accordance with the communication speed, content distribution businesses that is, the response performance it provides high Web service is "possible.
