  4. kr DNS Monitoring System Main page ( updated every 5 seconds )

  5. kr DNS Monitoring System Main page ( kr query per nation )

  6. What main page shows.... kr DNS Monitoring System 1) kr DNS Traffic, Performance , total value 2) kr DNS name server traffic, server resources, performances 3) Nameserver locations, and links to Display box 4) Showing AnyCast DNS 5) pop-up Window information    - Source IP TOP10    - ISP TOP 10    - Every nation query status

  7. kr DNS Monitoring System with sub pages

  8. What they (sub pages) show... kr DNS Monitoring System • Network traffic, server resources, DNS performance, every servers’ query statistics • each .kr DNS optional information - today, last week, last month,current • - MAX, MIN, AVG values

  9. kr DNS Monitoring System category of collecting information

  10. kr DNS Monitoring System H/W components

  11. kr DNS Monitoring System S/W components • DB server: Solaris(OS), oracle • Web server: Tomcat, Redhat(OS), OZ Report(chart, graphic), flash, java, jsp • analysis/admin server: Solaris(OS) • back-up server: Redhat(OS), oracle

  12. kr DNS Monitoring System Rooms for improvement • operation rate improvement • improve process, data transfer and administration • reduction of daemons, reduction of load • consideration apply standard S/W (open source) • packet analysis tool : DNSCAP • graphic/chart : Java. PHP

  13. kr DNS Monitoring System Rooms for improvement • we need to statistics IPv6 query per nations, and ISP • => IPv6 addressdeployment plan • we need to more security • - passive management : SMS delivery, alarm • - active management : IP Blocking

  14. kr DNS Monitoring System Rooms for improvement • Conversion (Web1.0 -> Web2.0 ) • Ajax(Asynchronous Javascript And XML) • > merits • - without page movement. quick display conversion • - don’t need to wait server’s handling, asynchronous request is possible. • - can reduce receive data amount. make the client handles it (delegation) • > demerits • - some browser couldn’t support Ajax. • - Http client’s function is limited. • - security problem (communication without page movement) • - supported Char-set are limited. • - Debugging is hard, ‘cause editing is with script.
