• Periodic Observation Report "Broadband Traffic Report:Traffic in a Stable Uptrend Post-COVID"[1.77MB]

  In this report, we analyze traffic over the broadband access services operated by IIJ and present the results each year. Here, we again report on changes in traffic trends over the past year, based on daily user traffic and usage by port. Traffic has continued to grow steadily since the COVID-19 pandemic fell into the rearview mirror, and at present we see no noticeable changes in that overall trend.

• Focused Research(1) "A Review of Research in System Software Communications Since 2010"[4.33MB]

  Network interface cards (NICs) supporting speeds above 10 Gbps became commonplace in the early 2010s and are now widely used in data-center and other applications.
  With the performance of NICs rising, the efficiency of the system software that controls this hardware, particularly its data communications, has become increasingly important, and the research community has pursued many avenues to improve this performance. In Section 2.2, I start by looking at the behavior of system software when processing communications. Section 2.3 then summarizes past research aimed at speeding this up. With that background in place, Section 2.4 then looks at IIJ Research Laboratory's efforts in this area in recent years.

• Focused Research(2) "Evolution of the IIJ Cloud-Commemorating 30 Years"[412KB]

  Over IIJ's history, we have provided Internet connectivity alongside a range of related services with a focus on communications. We have continued to enhance and expand the service hosts used to provide these services over the past 30 years, which now encompass several thousand servers. We also provide computing resources to customers through the IIJ GIO cloud service, the infrastructure for which has also grown to comprise tens of thousands of servers in the decade since launch. In this article, we take a look back at IIJ's 30-year journey. The first half describes how IIJ's service hosts have changed with the times and the innovations we have made in the process. The second half looks at how the IIJ GIO cloud platform has evolved through successive generations to become the large-scale service infrastructure it is today.
