31. connect communicate collaborate perfSONAR MDM in a nutshell perfSONAR MDM is the GÉANT multi-domain monitoring service Collaboratively deployed by GEANT and NRENs Objectives – three use cases from DICE: Network troubleshooting Circuit monitoring (including dynamic circuits/AutoBAHN) SLA verification Strategy: perform network monitoring actions in different network domains make the information available thanks to a common protocol – Cross-domain monitoring capability – Access network performance metrics from across multiple domains network problems and performance bottlenecks can be traced and eliminated quickly proactively identify and prevent problems before service disruption occurs

32. connect communicate collaborate perfSONAR MDM: accessing network information across several domains perfSONAR is carried out by a consortium of organisations (GÉANT, ESnet, Internet2 and RNP) perfSONAR aims at making it easier to solve end-to-end performance problems on paths crossing several networks. Authorized users can have access to network performance for diagnosis and troubleshooting

33. connect communicate collaborate perfSONAR as unifying layer across domains Domain 3 Domain 1Domain 2 Domain 4 perfSONAR Services perfSONAR Each domain has its own local monitoring perfSONAR UI (visualization) Scripts/API

35. connect communicate collaborate perfSONAR is based on OGF Standards perfSONAR philosophy: Open/Modular Multi-Domain (Web Services) Interoperable Integrates: Network measurement tools Network measurement archives Discovery (lookup service) Authentication and authorization Data Manipulation Topology Visualization perfSONAR uses the OGF NM-WG Recommendations (ontology) and Schemata

37. connect communicate collaborate End-to-End link monitoring in perfSONAR across multiple domains Point A PointB Domain A Domain B Domain C Goal: (near) real-time monitoring (link status) of the whole end-to-end Link A-B, when constituent links are crossing multiple domains E2ELink A-B

38. connect communicate collaborate perfSONAR E2EMon Approach: correlation of domain-based info Point A PointB Domain A Domain B Domain C E2ELink A-B perfSONAR MP or MA perfSONAR MP or MA E2Emon correlator perfSONAR Measurement Point (MP) or Measurement Archive (MA) DomainLink and (partial) ID_Link info E2E link view for users E2ECU operators

39. connect communicate collaborate How does E2E monitoring work Each domain installs software probes to capture up/down status of their links from network hardware This status info sent to a local perfSONAR Measurement Point Collecting network status info [UP / DOWN only] Historical archive for network status info Checks info and reformats into XML for collection The Correlation Engine then: Queries PerfSONAR Measurement points Concatenates information from constituent links to form End- to-End multi-domain links
