JRA1 D3.4 Flow Monitoring - conference call agenda & minutes
Contents |
Info
Date/time: 25th November 2005, 14:00 CET
Expected time of conference call: 1 hour
Agenda
- netflow servers installation plan (OS, additional services and tools)
- netflow enabled network equipment (list of routers/switches, flow export parameters, ...)
- First draft of an action plan (list of tool candidates, first set of testing goals, first draft of a time plan
Minutes
Attendees: Hans Trompert (HT), Luuk Oostenbrink (LO), Alessandro Inzerilli (AI), Mauro Campanella (MC), Andreas Solberg (AO), Jon Kare Hellen (JH), Maurizio Molina (MM), Nicolas Simar (NS), Igor Velimirovic (IV)
- Shipment: all three netflow testing boxes are delivered (GARR, Surfnet, CARNet)
- Installation: boxes will be installed next week, before 05.12.2005.
- OS: GARR will install Fedora Core 3 (kernel 2.6), Surfnet Fedora Core 4 (kernel 2.6), CARNet Debian (kernel 2.6). AI pointed that there were some problems with installation of a 64-bit OS and a flow-tools implementation; MM will check similar experience from DANTE and forward patches list to the AI. For now we will go with a 32-bit operating system. NS will check with perSONAR architects if there are any constraints regarding OS.
- Access to boxes: machine will be accessed only by hosting NREN. If needed, ssh access will be enabled to the other partners, to be requested at least one week before needed.
- Netflow export versions and modes: for now, work in parallel with netflow v.5 and v.9. There is a need to follow new developments within IPFIX wg; MM will forward to the mailing list a e-mail from Nevil Brownlee explaining differences between netflow v.9 and ipfix format. Considering sampling, for now many devices can only provide sampled exports.
- Netflow tool requirements: the list of requirements is ok. However, since we decided to support v.5, IPv6 is not a obligatory requirement any more, but will be listed.
- Network equipment: for a start, netflow wil be exported from a routers within each NREN. Not a problem to export from GEANT devices, but there is a privacy issue, and a NDA will be needed (MM). It might take a few weeks to arrange it.
- Tool candidates: AS described four basic functionalities that netflow tool can provide: capturing, reporting, aggregation, presentation. Each of the tool provides one or more functionalities, and therefore tools can be compared for a specific task only. We shortened list to a four tools with a capturing and reporting function (flow-tools, NERD, nfsen/nfdump, Ipflow) and one for a aggregation and presentation (STAGER). Those five tools will be tested. We need a test evaluation form.
- perfSONAR architecture: there is a need for a coordination with a prototype design, in order to prevent problem latter on. NS suggested to prepare description of request/reply procedures before January on order to discuss it with Martin Swany and other people from prototype group. NS proposed two solutions: to integrate netflow measurement points fully in a architecture and therefore provide all data to a measurement archives, or to provide only basic info to MAs and provide more detailed info directly to the users.
Actions
- SURFNET; GARR, CARNet to install OS on a boxes before 05.12.2005.
- IV to update wiki page: shortened list of a tools, requirements, etc. Also, start work on a coordination with perfSONAR team (DONE!)
- MM to forward info about netflow v.9 vs. ipfix format (DONE!)
- NS to check with perSONAR team if there are any OS constraints (DONE!)
- IV to propose test evaluation form (DONE!)
Next meeting 5th of December 2005, 14:00 CET
