Project Goal
Middleware
• Implementation of an operational environment for PCcluster 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 Goal
Applications (1)
• Usage/upgrading of (existing) applications with high and
dynamical 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
Terena, June 2005

Project Goal
Applications (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)

International
Aspects
• 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 FP6projects:
– GN2 - Geant2
– MUPBED - Multi-Partner European Testbeds for Research
Networking
• The testbed VIOLA forms the national base to contribute
successfully to international projects
• Interested for cooperation with similar projects/activities in
Europe and elsewhere
Terena, June 2005

Page 23
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 new
middleware 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
