2. © 2006 Open Grid Forum OGF24 Singapore September 2008 2 But the Network just works !  Grids always used resource information about: CPUs, memory, disks, Job queues  But later Grids need information about the Network resource: Decisions by the Middleware Resource Broker Performance investigations Network Operators & Capacity planning  Many monitoring frameworks – all different but need to interoperate  Must be able to describe the topology: Monitoring Policy Dynamic control  Networks are becoming dynamic – multi-domain on demand operation from the middleware.  Need for standard mechanisms to describe and publish network descriptions, performance characteristics, & enable dynamic control.

4. © 2006 Open Grid Forum OGF24 Singapore September 2008 4 Network Measurements WG  Focuses on Network Characteristics of interest to grid applications.  Developed standard mechanisms to describe and publish these characteristics to the Grid middleware, network operators etc.  Created a document categorising the Network Performance Characteristics for Grid Applications.  Created XML Schemata to publish and exchange the values of the observations of these characteristics along with attributes describing the measurement conditions.

5. © 2006 Open Grid Forum OGF24 Singapore September 2008 5 Characteristic Hierarchy Doc  “A Hierarchy of Network Performance Characteristics for Grid Applications and Services”  Document defines terms & relations: Network characteristics Measurement methodologies Observation  Nodes & Paths Defines the meanings Discusses the use & relations  For each Characteristic Defines the meaning Stated the attributes that SHOULD be included Discusses the issues to consider when making an observation  GGF Proposed Recommendation GFD-R.023 www.gridforum.org/documents/GWD-R/GFD-R.023.pdf

7. © 2006 Open Grid Forum OGF24 Singapore September 2008 7 perfSONAR Uptake & Deployment  perfSONAR is a joint effort: ESnet GÉANT2 JRA1 Internet2 RNP (Brazil)  ESnet includes: ESnet/LBL staff Fermilab  Internet2 includes: University of Delaware Georgia Tech SLAC Internet2 staff  GÉANT2 JRA1 includes: Arnes Belnet Carnet Cesnet CYNet DANTE DFN FCCN GRNet GARR ISTF PSNC Nordunet (Uninett) Renater RedIRIS Surfnet SWITCH  Other contributions & installations: CLARA (Latin American Cooperation of Advanced Networks) LHC Network JANET An OGF success story: 27 partners

8. © 2006 Open Grid Forum OGF24 Singapore September 2008 8 Network Mark-up Language WG  Working to describe network topologies with a standardized network description ontology and schemata  The work will: facilitate interoperability between different projects. allow creation of inter-domain network graphs at various abstraction levels provide an information model for service discovery facilitate on-demand multi-domain network provisioning such as QoS, point-to-point lightpaths, Lambdas Feed into standards from other OGF working groups

11. © 2006 Open Grid Forum OGF24 Singapore September 2008 11 Network Service Interface WG  First WG meeting in OGF24  Interest & support from industry – grid operators, network equipment vendors industry partners include NTT, KDDI, Nortel and Alcatel-Lucent Bell Labs  Build on research projects including: Phosphorus, AutoBahn, DICE, and G-Lambda  Involves currently deployed dynamic networks such as ESnet, Internet2, GÉANT, Surfnet  There is a real demand from users

12. © 2006 Open Grid Forum OGF24 Singapore September 2008 12 Summary  There is a real demand from users for advanced network facilities  The need for inter-operation between domains & providers drives the need for standards  OGF facilitates co-operation & collaboration A document series for Standards
