  12. Grid High Performance Networking RG • It produced a set of use cases capturing the interaction between applications and grid network middleware (GFD-I in early 2007) • Constituency is highly specialized in the type of networks used in R&E testbeds • Now actively engaging GLIF and EU-funded Phosphorus participants --- they will jointly produce GFDs (OGF is the only group in this bunch with a document process) 12

  15. Grid and Virtualization Working Group • Chairs • Erol Bozak (SAP) • Development Architect • NetWeaver Solution and Platform Management • Wolfgang Reichert (IBM) • Senior Technical Staff Member (STSM) • IBM On-demand Operating Environments • Goals • Verification that within existing Grid standards the specifications are neutral to “virtualized systems / resources” • The request for resources may be satisfied either by / with “virtualized systems” or “physical systems” • “Virtualization is transparent to the Grid” (e.g. resource provisioning) • Define use cases wherein the grid infrastructure is seen participating in an virtualized system infrastructure • Explore how virtualization technologies can be leveraged to better support grid use cases • Define one or more profiles that allows the Gird infrastructure to : • Monitor • Manipulate, • Migrate Virtual Systems etc. 15

  23. NML-WG: Network Mark-up Language Chairs: Paola Grosso - UvA Martin Swany - Udel Purpose: to describe network topologies, so that the outcome is a standardized network description ontology and schema, facilitating interoperability between different projects. The scope is to define one or more schemas to describe: • a layer independent network topology • properties that are common across multiple network technologies, • a mechanism so that other working groups or other projects may combine technology specific schemas with the schemas created by the NML working group. Such a schema can be used to create inter-domain network graphs at various abstraction levels, to provide an information model for service discovery, and to facilitate lightpath provisioning. First official meeting at OGF20 in Manchester. See you there! 23

  25. Current status: NDL NDL - Network Description Language - an RDF based model for hybrid network descriptions. It leverages all the semantic web tools, to provide: • parsing of the RDF files • graphs and visualization of connections and lightpaths • lightpath provisioning support at inter and intra domain level. Latest developments were presented at the GLIF meeting in Sep. ‘06. Google-maps and NDL… …the GLIF connections described by NDL. 25
