In this report we analyze traffic over the broadband access services operated by IIJ every year and present the results.We once again report on changes in traffic trends over the past year based on daily user traffic and usage by port. From this report,we will also report on traffic trends for mobile service traffic in the same way.
We cover big data. Concepts such as IoT and CPS have been in the limelight a lot lately, but in the world of social networking, these make up just one slice of the huge variety of data transmitted.
