© 2006 Open Grid Forum 3 New Solutions, Architectures, Technologies and Services are Emerging Evolving Grid Network Architectures: Proprietary solutions for specific implementations. G-Lambda, Enlightened, Phosphorus, 3TNET, … Need interface that can provide interoperable procedures between a wide range of service provisioning systems. Support of a number of distinct layer architectural models across geographical organizational boundaries, heterogeneous environments with different Grid service provisioning systems (co-allocation services, Brokers, etc.), Network Resource Provisioning Systems Control plane (e.g. GMPLS, Grid-aware GMPLS) Transport planes (e.g. Ethernet, SDH, OTN, OBS) Policy, security standards.

B) East-West IF: It is in charge of the communication between NRPSs. C) Topological IF: It is used to indicate to the NSP which resources are under control (NRPSs, endpoints, links). D) Southbound IF: It Communicates the NRPSs and the lower layers (GMPLS or transport layer). E) Phase 2 IF: It provides interoperability between the NSP and the G 2 MPLS CP or other projects.

© 2006 Open Grid Forum 23 Requirements

© 2006 Open Grid Forum General Requirements I 1.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 2.Extensibility: GUNI architecture needs to scale to potentially support any possible Grid/network service provisioning system 24

© 2006 Open Grid Forum General Requirements II 3.Performance and agility: GUNI should dynamically adjust the service provisioning level (e.g. Bandwidth provisioning) and accept different signal types and levels of granularity. 4.QoS assurance: Service Level Agreement Reliability 5.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 6.Failure notification 25

© 2006 Open Grid Forum 30 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.
