3. GEANT Performance Monitoring Infrastructure – Joint Techs meeting July 2004 -- Nicolas Simar (Nicolas.Simar@dante.org.uk) Introduction Multi-domain Network Performance Measurement Management Platform – Retrieve network information from several domains through a pre-defined interface. – Performance Monitoring: provide network characteristics such as available bandwidth, delay, packet loss, “traceroute” extended to looking glass functionality netflow like data (to track DoS attack) else (your feedback welcome)

4. GEANT Performance Monitoring Infrastructure – Joint Techs meeting July 2004 -- Nicolas Simar (Nicolas.Simar@dante.org.uk) Introduction (2) Multi-domain Network Performance Measurement Management Platform provides an “aggregated/concatenated” view of the information retrieved. – R1 -> R2 = 1.2Gbps ; R2 -> R3 = 800Mbps ; R3 -> R4 = 1.6Bbps – R1 -> R4 = 800Mbps allows to generate some traffic with some specific characteristics. – Generate

5. GEANT Performance Monitoring Infrastructure – Joint Techs meeting July 2004 -- Nicolas Simar (Nicolas.Simar@dante.org.uk) PERT - the need of addressing the end-to-end problem and provide for the network side a tools for the PERT group. – PERT stands for Performance Emergency/Enhancement Response Team (http://www.dante.net/server/show/nav.00100q003003/) Users (NRENs) and users’ users (GRIDs, application over network researchers) are requesting more and more information from the networks. Introduction (3)

6. GEANT Performance Monitoring Infrastructure – Joint Techs meeting July 2004 -- Nicolas Simar (Nicolas.Simar@dante.org.uk) Overview Objectives – Exchange monitored data between domains to Ease the troubleshooting (fault/problem localisation) Give to the network users (for instance end-site systems administrator or advanced network users) views of the networks-edge to network-edge performances. Network/service health verification. SLA verification – Re-usable parts (as much as possible). – Extendable to new type of tests. – Each domain has its own policy.

9. GEANT Performance Monitoring Infrastructure – Joint Techs meeting July 2004 -- Nicolas Simar (Nicolas.Simar@dante.org.uk) Measurement Point (MP) – “something” (router, piece of software, etc) capable of providing information about a network characteristics (delay, routing info, interface status, etc) – For a given type of measurement, different type of MP could be used. (e.g. delays: DFN IPPM on GÉANT, OWAMP on Abilene). Implies inter-operability issues (packet format, way of requesting a test between domains, etc). Building blocks

10. GEANT Performance Monitoring Infrastructure – Joint Techs meeting July 2004 -- Nicolas Simar (Nicolas.Simar@dante.org.uk) “User” Interface – Presents network information (OWD so far) from a domain, uses the request and reply schema defined by the GGF NM-WG. – Using XML RPC – Allows to start measurements from/to MPs not under our administrative authority. Need also interface for the path finder and the AA. Building blocks (2)

11. GEANT Performance Monitoring Infrastructure – Joint Techs meeting July 2004 -- Nicolas Simar (Nicolas.Simar@dante.org.uk) “Domain Manager” – Primary goal: collects the data, concatenates them (if requested), aggregates them (if requested) and/or analyses them (if needed). Query the path finder about which MP and which domain tool have to be contacted. Query the domains MPs and other domains. Schedules tests, do resource management on behalf of the MPs, negotiate test with other domains. Authentication, authorisation. Format data according to predefined format. Building blocks (3)

12. GEANT Performance Monitoring Infrastructure – Joint Techs meeting July 2004 -- Nicolas Simar (Nicolas.Simar@dante.org.uk) Path Finder – High level functionality: locate the measurement nodes along a end-to-end path. Two cases – the full path is given – only end points are given »trickier – Historical path variation difficult to provide Implies limitation concerning the end-to-end information which can be provided. Building blocks (4)

13. GEANT Performance Monitoring Infrastructure – Joint Techs meeting July 2004 -- Nicolas Simar (Nicolas.Simar@dante.org.uk) Authentication/Authorisation – High level functionality: authenticate a user and allow him to get the data he is authorised access and to start test based on its level of authorisation. e.g. domainX.NOC or domainX.user_type Building blocks (5)

14. GEANT Performance Monitoring Infrastructure – Joint Techs meeting July 2004 -- Nicolas Simar (Nicolas.Simar@dante.org.uk) MPs deployment DFN IPPM – GEANT Frankfurt (DE), GEANT Jerusalem (IL), PSNC Poznan (PL), GARR Rome (IT), Renater Paris (FR). Data available September OWAMP – On the same monitoring hosts than the DFN IPPM, plus GEANT London (UK) and GEANT Geneva (CH) BWCTL – GEANT London (UK), GEANT Milano (IT) RIPE TTM – GEANT Geneva (CH) Will be able to provide information from more RIPE TTMs (NRENs have offered to include theirs).

15. GEANT Performance Monitoring Infrastructure – Joint Techs meeting July 2004 -- Nicolas Simar (Nicolas.Simar@dante.org.uk) Agenda GN1 performance monitoring trial GN2-JRA1 Performance Monitoring and Management – Objectives

16. GEANT Performance Monitoring Infrastructure – Joint Techs meeting July 2004 -- Nicolas Simar (Nicolas.Simar@dante.org.uk) JRA1 Objectives Performance Monitoring and Management Provide a multi-domain framework to exchange monitoring information. – For the end-to-end services offered by the GN2 community. Information retrievable through a pre-defined interface. – Visualisation tools can access the data using a same format independently of the domain from which the data are retrieved. 10 FTE over three years (Joint Research Activity) – 14 European NRENs involved

17. GEANT Performance Monitoring Infrastructure – Joint Techs meeting July 2004 -- Nicolas Simar (Nicolas.Simar@dante.org.uk) JRA1 Benefits Better visibility on what is happening along the e2e path. Easier troubleshooting. Raise awareness about where the problems are. Provide a better feel of satisfaction to the end- users towards the network. Share development resources. Create a monitoring community in Europe.

18. GEANT Performance Monitoring Infrastructure – Joint Techs meeting July 2004 -- Nicolas Simar (Nicolas.Simar@dante.org.uk) Three levels

19. GEANT Performance Monitoring Infrastructure – Joint Techs meeting July 2004 -- Nicolas Simar (Nicolas.Simar@dante.org.uk) Visualisation Data consumer (user visualisation interface) – Adapted to different type of users NOCs GRID and projects End-users Researchers in the field of network or application over computer network – Uses per-defined interface for retrieval of monitoring data independently of the domain where the data are coming from. – Development of at least three visualisation tools (among them: map for users/NOCs/GRIDs and SLA verification)

20. GEANT Performance Monitoring Infrastructure – Joint Techs meeting July 2004 -- Nicolas Simar (Nicolas.Simar@dante.org.uk) Domain Controller Bring the multi-domain dimension to the system Bridge the visualisation tool with the measurement tools. Measurement points discovery and path discovery. Perform functions on behalves of the measurement points (scheduling tests, etc). AA with other domain controller/framework, with measurements and visualisation tools. – GN2-JRA5 is in charge of building an AAI.

21. GEANT Performance Monitoring Infrastructure – Joint Techs meeting July 2004 -- Nicolas Simar (Nicolas.Simar@dante.org.uk) Measurement Points Enhancements of existing tools Work in two areas: – For active monitoring: (a) one-way-delay and (b) throughput measurement tools AA, security and inter-operability – For Passive monitoring: (a) flow monitoring (netflow like), (b) passive packet capture tool and (c) network equipment information.

22. GEANT Performance Monitoring Infrastructure – Joint Techs meeting July 2004 -- Nicolas Simar (Nicolas.Simar@dante.org.uk) Collaboration with Internet2 piPEs – Frameworks should be inter-operable “User” interfaces Interface between the framework and the end-users Protocols for active measurements. Discovery mechanisms AA – Reconciliation of the infrastructure – Test of tools – Investigation of the set up a shared development environment – Write common architecture description – Interim-roll out of common measurement environment

23. GEANT Performance Monitoring Infrastructure – Joint Techs meeting July 2004 -- Nicolas Simar (Nicolas.Simar@dante.org.uk) Collaboration with other Activities (6) EGEE – Enable Grids for E-science in Europe – Objectives: deployment of an operational GRID infrastructure. – They will need to access monitoring information from the domain. Interface to retrieve the data Interested mostly in information which can be of any use at the L4 and in Available Bandwidth.
