PHOSPHORUS Key Features Integration between application middleware and transport networks, based on three planes: – Service plane: • Middleware extensions and APIs to expose network and Grid resources and make reservations with those resources • Security mechanisms (AAA) for network domains participating in a global network infrastructure, allowing both network resource owners and applications to have a stake in the decision to allocate specific network resources – Network Resource Provisioning plane: • Adaptation of existing Network Resource Provisioning Systems (NRPS) • Implementation of interfaces between different NRPS to allow multi–domain interoperability with Phosphorus’ resource reservation system – Control plane: • Enhancements of the GMPLS Control Plane (Grid-GMPLS or G² MPLS ) to provide optical network resources as first-class Grid resource • I nterworking of GMPLS-controlled network domains with NRPS-based domains, i.e. interoperability between G 2 MPLS and Argia/ UCLP , DRAC and ARGON 7 th NREN and Grids workshop, Dublin (I reland), September 2008
PHOSPHORUS Architecture
Harmony system: NRPS and NSP interfaces (WP1) NBI: It receives the reservation requests from the TOPOLOGICAL GRID APLICATIONS Grid Middleware. It is used to indicate to the CONFIGURATION & MIDDLEWARE NSP which are the resources under control (NRPSs, endpoints links). NBI NBI EWI: It is in charge of the communication between PHASE 2 NRPSs. Network Service Request Handler Scheduler OTHER SBI : It handles the communication between the PROJECTS NRPSs and the lower layers (GMPLS or transport layer). Reservation Path Computer Handler EI It provides intero-perability between the NSP EI: and the G 2 MPLS CP or other projects.

The NRPS systems Network Resource Provisioning Systems (NRPSs) The Allocation and Reservation in Grid-enabled Optic Networks system was developed to manage resources of advanced network equipment as it is present in the German VIOLA test- bed. The advance reservation service of ARGON is able to operate on the GMPLS as well as on ARGON the MPLS level. It guarantees a certain QoS for applications for the requested time interval. This feature enables a Meta-Scheduling Service to seamlessly integrate the network resources into a Grid environment. The Dynamic Resource Allocation Controller system was developed by NORTEL and it is a commercial-grade network abstraction and mediation middleware platform, acting as an agent for network clients (users, applications, compute resource managers) to negotiate and reserve DRAC appropriate network resources on their behalf. DRAC uses client's QoS requirements and pre- defined policies to negotiate end-to-end connectivity across heterogeneous in support of just-in- time or scheduled computing workflows. The User Controlled LightPaths is provided by CRC, Inocybe and i2CAT. It provides a network virtualization framework upon which communities of users can build their own services or applications. Articulated Private Networks (APNs) are presented as the first services. An APN UCLP can be considered as a next generation Virtual Private Network where a user can create a (ARGIA) complex, multi-domain topology by binding together network resources, time slices, switching nodes and virtual/real routing services.
Current prototype: the Harmony Architecture Key points: • Distributed (P2P) or hierarchical architecture for the Network Service Plane • Harmony Service Interface common for the adaptation layer and the network service plane • The Network Service Plane is composed by independent entities (Inter Domain Brokers) • The distinct IDBs flood the information of each domain they control • The new P2P architecture is being tested over the new virtual testbed 7 th NREN and Grids workshop, Dublin (I reland), September 2008

The NRPS Manager (as part of the NSP) • Module inside the NSP in charge of direct communications with NRPSs, by means of their endpoints • It coordinates the call from the NSP to the NRPSs adapters and returns the replies • The requests to the NRPSs adapters are launched at the same time to let the NRPSs work in parallel in order to shorten the request processing time.
