Summary of Network Monitoring Working Group

The Network Monitoring Working Group aims to establish a unified assessment of connectivity performance within the ICFA community. By deploying ping metrics for end-to-end performance measurements across 12 sites in 7 countries, the group has gathered data on 400 link pairs using standardized tools and data formats, archived at HEPNRC. Key issues include data management, link quality ranking, and categorization of links. Essential efforts involve developing analysis tools and fostering relationships with ISPs to enhance connectivity and resolve issues.

  1. Summary of Network Monitoring Working Group • Mission of Group: • Obtain as uniform picture as possible of the present performance of the connectivity used by the ICFA community • Using ping metrics to make end-to-end performance measurements • Have 12 sites in 7 countries collecting data on 400 link pairs, using common documented tools & data format • Data being gathered and archived at HEPNRC • Have some common tools for analyzing and presenting the data via the Web ICFA Santa Fe Meeting

  2. Top Two Major Issues • How Do We Cope With All the Data (collecting 200MBytes/month) • Group By Interest, Experiment, Country, Type, AS ... • Ranking Quality of Links • Categorise Links by Type of Usable Service (mail, FTP, WWW, etc.) • Weather Maps, Weekly Summary • Need Additional Analysis Effort (to develop tools) and more Collecting Sites • Efforts: • Medium Amount of Effort to Develop Analysis Reports • Small Amount of Error to run a Collection Site ICFA Santa Fe Meeting

  3. Other Major Issues • Lobbying for Change / Building Relationship with ISPs • Rely on Service Providers to Resolve Problems? • Problem with C in A->B->C->D->E? Should A contact C? • ICFA May Be Able to Help • New Tool Development • Port SLAC Report Generation to Support Multiple Source • Port TracePing to PERL • HTTP, FTP transfers ICFA Santa Fe Meeting
