  18. GUNI Role in Grid Networking environment 19

  19. GUNI Reference Point Grid- Network service interface that links any type of Grid End or Grid Service Point with a broadened Network Provisioning System. 20

  21. GUNI Activities • Grid Network Service Activities 22 Network Activities

  22. Requirements 23

  23. General Requirements I • Interoperability: GUNI must be able to interface to any software, hardware and service boundaries between different layers • Grid Middleware • Grid Users/Resources • NRPS • GMPLS • Grid-aware GMPLS • OBS • Extensibility: GUNI architecture needs to scale to potentially support any possible Grid/network service provisioning system 24

  24. General Requirements II • Performance and agility: GUNI should dynamically adjust the service provisioning level (e.g. Bandwidth provisioning) and accept different signal types and levels of granularity. • QoS assurance: • Service Level Agreement • Reliability • Security and Policy: GUNI should provide means to check and forward service credentials for using grid and network resources and accounting for the real resource usage. • Authentication and authorization • Failure notification 25

  25. GUNI Architecture and Functionalities 26

  26. NS architectural model with regards to GUNI • GUNI accepts connection requests from the Grid MW and establishes a new session with the NPS 27

  27. Network Services supported by GUNI • Connection creation • Connection deletion • Connection status enquiry • Network Topology Enquiry and Restoration • Network Resource Capability • Network Resource Availability • Network Advance Reservation • Traffic classification and shaping • Data plane enhanced security 28

  28. Grid Network Services supported by GUNI Grid services mainly allow on-demand access to Grid resources considering reservation, allocation, actual use and release. Moreover, procedures such as discovery of capability and availability of computational resources are also required in order to facilitate Grid resource management. • Grid Service Discovery • Grid Resource Discovery • Grid Advance Reservation Request • Grid Advance Reservation Cancellation 30

  29. Abstract messages and procedures 31

  30. Abstract messages for Overlay model 32

  31. Abstract messages for Integrated model I 33

  32. Abstract messages for Integrated model II 34

  33. Procedures - Message flows 35

  34. Network Service: Create, Reject, Delete 36

  35. Grid Network Service: Create 37

  36. Grid Network Service: Delete & Reject 38

  37. Grid Capability & Availability Advertisement 39

  38. Future plans • Incorporate final remaining contributions. • Await for comments from GHPN members. • Finalise and Submit before next OGF meeting. • Possible organization of BoF in OGF Europe as a follow up… with consideration on creation of GUNI-WG • Interact with other OGF groups (GRAAP, JSDL, GLUE,…) • Identify and agree on message transactions • Identify the platform (e.g. WS-Agreement, WS or …) 40
