  1. GN2 Performance Monitoring & Management : AA Needs2nd AA Workshop20 - 21 November 2003Malaga, Spain Nicolas Simar, Network Engineer DANTE

  2. Introduction • GN2 project starting from Q3 2004 • build the successor of the GÉANT network • integrated activities between NRENs: Joint Research Activities (JRA) and Services Activities (SA) • AA required by various activities in GN2 (non extensive lists) • JRA1 – Performance monitoring & management • JRA3 – BW allocation & reservation • SA3 – end-to-end service quality across multiple domains • Need to define a common EU-wide AA architecture (JRA5-Ubiquity and/or JRA2 Security?)

  3. What is JRA1? • Multi-domain Network Performance Measurement Management Platform • Retrieve network information from several domains through a pre-defined interface. • Performance Monitoring: • monitoring of network characteristics such as delay, packet loss, available bandwidth, “traceroute”, etc • extended to looking glass functionality • netflow like data (to track DoS attack)

  4. What is JRA1? • Management platform • Provide an “aggregated/concatenated” view of the information retrieved. • Available bandwidth R1 -> R2 = x Mbps ; R2 -> R3 = y Mbps ; R3 -> R4 = z Mbps • Available bandwidth R1 -> R4 = min(x,y,z) Mbps • Enable users to generate traffic and its characteristics. • Generate flow <IP (destIP, tos, size, etc); TCP/UDP (port, etc)> • Allow to retrieve information out of several domains.

  5. Performance Monitoring Overview

  6. Where does it come from? • PERT (Performance Enhancement Response Team) need to isolate and resolve end-to-end problems. • The performance monitoring architecture should provide an useful debugging tool for this group. • Users are requesting to have access to more and more network information. • GRID to check what is the best way to ship data. • Network/application researchers to investigate the result of their experiments.

  7. Objectives • Exchange monitored data between domains to • Ease the troubleshooting • Give to the network users (for instance end-site systems administrator or advanced network users) more information about networks-edge to network-edge performances (later on, end-to-end for end-users). • Network/service health verification. • SLA verification. • Re-usable parts (as much as possible). • Must be able to cope with new type of tests/network characteristics. • Heterogeneous monitoring architecture in different domains

  8. AA Requirements • Different groups of users can perform different actions (e.g.) • Network end-user can access a subset of monitoring data. • NREN NOC can access a subset of data and perform some test using measurement points (MP) not under his/her administrative authority. Some limitations are applied to the tests he/she can perform. • The domain NOC can access any data and perform any test without limitation within its administrative authority. • Which groups are foreseen? • Domain NOC (NREN) • Other Domain NOC (NREN) • Customer NOC (campus sys-admin, regional network NOC) • Special end-users distributed over different domains or not (GRID - EGEE) • Generic end-user (default)

  9. AA Requirements • Every domain must stay in control of its monitoring infrastructure. • it decide which group can access which data and which group can do what with its MPs • it need to authenticate the user, map him/her to a group of user and check the what this group is authorised to do. • AA between the monitoring tools in different domains? • Cross domain AA for the end users? • e.g. a user in domain D1 should be able to start a test between MP’s in domain D2 and domain D3 • Flexible & extensible distributed AA architecture.

  10. Other GN2 activities • SA3 : e2e service quality • they may automate the service provisioning. • may need some modules to authenticate and authorise the user requesting the service (for GRID - EGEE) • JRA3: new services • build a new service providing end-to-end L2 connectivity • may also need to automate the provisioning of the service • JRA2: security and JRA5: ubiquity

  11. Other Issues • What can we do? • Use the JRA-5 AA architecture or some part of it? • Adapt an AA architecture to our needs (or to the ones from other GN2 activities)? • Develop another scheme? • Solicit advice regarding AA implementation in GN2 for the JRA1. • There are two main types of users. • Domain specific users • Cross Domain users • Compatibility with internet2 PiPEs.
