Analysis and Applications of Internet Traffic Measurement

以下四个研究项目是拟议研究的结果和成果。(1)互联网流量数据存储库的设计和运行存储库系统必须是安全的，并保护用户的隐私，与评估的流量数据。在研究过程中，知识库已经开发并实际运行。(2)根DNS服务器的流量分析根DNS服务器之一（即，M-Root服务器在日本）已被捕获和分析。分析表明，非亚洲国家的访问量大于亚洲国家。(3)标签交换系统中标签数的估算利用实际的流量数据，估算出Internet中所需的标签数。提出了新的方法，并使用实际的交通数据进行评估。(4)IP电话会议系统中数字视频传输的流量分析利用实际网络对使用IPSec功能的数字视频数据传输进行了评估。

The following four research items are the result and outcome of the proposed research.(1) Design and Operation of Repository for Internet Traffic DataThe repository system has to be secure and preserve the privacy of the users, associated with the evaluated traffic data. In the research, the repository has been developed and practically operated.(2) Traffic Analysis for Root DNS ServerThe traffic pattern at one of the root DNS server (i.e., M-Root Server in Japan) has been captured and analyzed. The analysis informs that the access from non-Asian country is larger then from Asian countries.(3) Label number evaluation for label switch systemUsing the actual traffic data, the required number of labels in the Internet is evaluated. The novel method is proposed and evaluated using the actual traffic data.(4) Traffic analysis for Digital Video transmission in teleconference system over IPDigital video data transmission using the IPSec function has been evaluated using the actual network.
