1 Solving End to End connectivity with GMPLS Radek Krzywania, PSNC, Poland April 4th 2008, Munich NGN meeting
2 Phopshorus project European and Global alliance of partners to develop advanced solution of application level middleware and underlying management and control plane technologies Project Vision and Mission The project will address some of the key technical challenges in enabling on demand end to end network services across multiple heterogenous domains In the Phosphorus' implementation the underlying network will be treated as first class resource Phosphorus will demonstrate solutions and functionalities across a test bed involving European NRENs, GÈANT2, Cross Border Dark Fibre and GLIF 2
3 Phosphorus partners NRENs & RON: Universities and Research Institutions: CESNET Communication Research Centre PSNC Fraunhofer Gesellschaft SURFnet Fundació I2CAT MCNC Forschungszentrum Jülich Manufacturers: Interdisciplinair instituut voor BreedBand Technologie Research Academic Computer Technology Institute Research and Education Society in Information Technology SARA Computing and Networking Services University of Bonn University of Amsterdam University of Essex University of Leeds ADVA Optical Networking Hitachi Europe Ltd. NORTEL SMEs: Nextworks 3
4 Phosphorus Key Features Demonstrate on demand service delivery across multi domain/multi vendor research network test beds on a European and Worldwide scale. The test bed will include: EU NRENs: SURFnet, CESNET, PIONIER as well national test beds (VIOLA, OptiCAT, UKLight) GN2, GLIF and Cross Border Dark Fibre connectivity infrastructure GMPLS, UCLP, DRAC and ARGON control and management planes Multi vendor equipment environment (ADVA, HITACHI, NORTEL, Vendor s equipment in the participating NREN infrastructure) 4
5 Phosphorus Key Features Develop integration between application middleware and transport networks, based on three planes: Service plane: Middleware extensions and APIs to expose network and resources and make reservations of those resources Policy mechanisms (AAA) for networks participating in a global hybrid 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) to support the framework of the project Implementation of interfaces between different NRPS to allow multi domain interoperability with Phosphorus resource reservation system Control plane: Enhancements of the GMPLS Control Plane (G²MPLS) to provide optical network resources as first class resource Interworking of GMPLS controlled network domains with NRPS based domains, i.e. interoperability between MPLS and UCLP, DRAC and ARGON 5
6 Phosphorus Key Features Studies to investigate and evaluate further the project outcomes : Study resource management and job scheduling algorithms incorporating network awareness, constraint based routing and advance reservation techniques Develop a simulation environment, supporting the Phosphorus network scenario Disseminate the project experience and outcomes, toolkits and middleware to NRENs and their users, such as Supercomputing centres 6
7 PHOSPHORUS ARCHITECTURE The different domains of the Phosphorus'test bed will have: middleware UNICORE as a reference point AAA policies Three types of NRPS: UCLP DRAC ARGON Two flavours of GMPLS standard (Ph. 1) enabled (Ph. 2) 7

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 are the resources 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 MPLS CP or other projects. 8
9 Reservation Handling in Phosphorus 9
10 Thin NRPS for GMPLS CP Thin NRPS: is a network resource provisioning system for domains with a GMPLS control plane. It is a NRPS with restricted functionality Middleware Provides advance reservation services (checking end points availability and possible overlapping reservations) Provides notifications receiver interface Acts as a client of the Topology manager WS of the NSP Web service identical Provides a reservation web service to reserve, create and delete network connections via the GMPLS driver NSP Topology manager Web service Client Web service Client THIN NRPSclaus.riemann@zv.fraunhofer.de Notification receiver Client Web service Notification sender GMPLS Driver Acts as a client of the GMPLS driver Domain registering GMPLS control plane Handles reservation request from NSP Network devices 10
11 The GMPLS Driver GMPLS driver: an interface between NRPS and the GMPLS CP. It is a general WS to create, delete and monitor paths for different GMPLS implementations, provides a WEB interface for testing the WEB service, Internal data base containing topology, path and status information, modules for accessing vendor specific GMPLS control planes (e.g. Alcatel Lucent or Nortel) and G(²)MPLS interface to GMPLS GMPLS driver services: Path creation Path termination Path monitoring Path discovery Endpoint discovery Registration service Path delete notification EndPoint update notification 11
