• Periodic Observation Report "Internet Trends as Seen from IIJ Infrastructure"[1.16MB]

  In this report, we examine and discuss current Internet trends based on information obtained by operating this infrastructure. We cover the topics of network routing information and DNS query information, as well as the usage status of IPv6 and mobile access services. We also report on the current state of the backbone network that supports the bulk of IIJ's traffic.

• Focused Research (1) "VSS Does Not Protect User Data"[4.77MB]

  VSS, an abbreviation for Volume Shadow Copy Service, is a backup-related function found in Windows XP / Windows Server 2003 and later versions of Windows. We confirmed an issue in Windows 8.1/10 where user data is not saved correctly to snapshots even when VSS is enabled. We investigated the cause of this and the scope of its impact. We also discuss methods for handling this issue here.

• Focused Research (2) "The Commercialization and Economic Sphere of Video Over IP Technology"[2.07MB]

  From both a technological and business perspective, we have reached the dawn of a new era in video over IP. Standards for this technology are expected to be published in 2018, and manufacturers are scrambling to comply with these standards. Broadcasters in North America and Europe are also rapidly showing an interest, and sessions featuring this technology have been held at broadcasting equipment exhibitions in Japan. In this report, we will provide details on video over IP technology that many stakeholders have high hopes for.

• Focused Research (3) "Intent-Based Network Security"[204KB]

  In this report, we examine intent-based networking (IBN), which is said to be the next big thing after SDN and SD-WAN. With IBN, IIJ aims to realize a new system for security that assumes a zero trust environment. We provide concrete details about this initiative, and discuss its future prospects.
