Considered to be a supportive move for Docomo’s eventual unleash of “extra-high-speed LTE services over its emerging IP-based mobile networks”, these two new technologies are dedicated individually to detect and locate the so-called “silent failures” in IP networks. Compared with the usual method of utilizing a dedicated device, these technologies seem to have proved to be far more time-efficient as the conventional method requires continual transmission of data throughout the entire network followed by the analysis of the test results, whereas they analyze not only test transmissions but also loss rates and network delays as well as detecting “warning signs of silent failures that are possibly about to occur”, and “identify the location of silent failures by analyzing data only from routes over which data is actually being transmitted”.

Docomo reports to have already conducted trials on its existing FOMA 3G network with the new technology having identified failure locations by up to 80 percent faster than the conventional method.
