Project GoalMiddleware

• Implementation of an operational environment for PC-cluster based on UNICORE– UNICORE supports the operation of a Compute-Grid– Interoperability with Globus-toolkit and compatibility with OGSA

(Open Grid Services Architecture) is planned

• Development / Portation of missing components– Development of a Meta-Scheduler based on Global Grid Forum

Standards (Grid Resource Allocation Agreement Protocol)– Portation of MetaMPI and integration in UNICORE– Adaptation/upgrading of local tools to connect and analyse

distributed applications– Development of high-performance parallel-I/O-interfaces (main

memory, file server)


Project GoalApplications (1)

• Usage/upgrading of (existing) applications with high anddynamical transfer requirements (e.g. e-science / Grid)– Several GE-tunnels per application– Dynamical requirement of bandwidth with guaranteed QoS– User controlled networks (E2E)

• Integration of real users– Variable requir. (time,size,quality) for „stress-test“ of network

equipment

• Based on experiences with new networks– Creation of new ideas for applications– Motivation of user groups for GRID-technology


Project GoalApplications (2)

The chosen applications will• Create high throughput requirements (Multi-Gigabit/s)• Demand latency and jitter limits• Demand bandwidth reservation, dependent on time• Support performance analysis of the network• Enable operational experiences with new network technology (e.g.

management)• Demonstrate the capabilities of the new network technology for

challenging applications

• Integration of further non-funded applications– national and cooperation with international projects (FP6)

InternationalAspects

• DFN participates in EGEE (Enabling Grids for e-science in Europe)– international Grid-Infrastructure based on existing networks

• „VIOLA-Participation“ (DFN, TSI, Uni Erlangen) in FP6-projects:– GN2 - Geant2– MUPBED - Multi-Partner European Testbeds for Research

Networking

• The testbed VIOLA forms the national base to contributesuccessfully to international projects

• Interested for cooperation with similar projects/activities inEurope and elsewhere


Status (1)

• The testbed implementation is finished:– circuits are connected (including connection to G-WIN/GEANT)– equipment is installed;– network management is operational

• Work items of „Transport & Signalling“ have been started:– I-NNI: Provision for Siemens-hiT7070– E-NNI: Provision for Alcatel-1678 and Sycamore-SN16000– E2E: Specification of user interface & design of reservation system

• Viola-Lab (test environment) is established:– VPLS and H-VPLS interoperability tests between Alcatel & Riverstone– E-NNI interoperability tests between Alcatel & Sycamore– GFP/LCAS-Tests between Alcatel-1678 & Siemens-hiT7070


Status (2)

• Initial version of middleware is deployed, Integration of newmiddleware components in progress

• Application projects have finished preparatory work

• First “runs” over the network have been made

Applications are beginning to stress network &middleware.


Summary (1)

VIOLA will support (beyond the specific project goals):• Reflection on and influence to changing conditions in

research networks– new user requirements (e.g. e2e) demand new architecture– maybe new operating models (e.g. usage of „dark fibre“)

• Cooperation with international activities– Cyber-Infrastructure (USA) or CANARIE (CA)– IST program of EU– national programs in Europe (e.g. NL, CH, PL)

• Cooperation with national programs and projects– D-Grid (e-science), MultiTeraNet, TransiNet


Summary (2)

• Usage of VIOLA-platform for further NGN-topics• German industry to test and develop future network

techniques and services• Implementation of innovative (bandwidth demanding) VR-

and Grid-applications• Preparation of the X-WIN
