Network
Signalling (4)
• Provision of Ethernet-Service over SDH with bandwidth
adjustment (New SDH: GFP, LCAS, VC).
– GFP: Generic Framing Procedure (ITU-T G.7042), method to transport
data packets (e.g. Ethernet) over SDH
– LCAS: Link Capacity Adjustment Scheme (ITU-T G.7041), dynamical
bandwidth adjustment for SDH-links (variable VC4-container)
– Virtual Concatenation (VC) instead of Continuous Concatenation (CC):
VC4-Container may use different ways in the transport network
• First New-SDH-Results
– Basic tests/interworking between Alcatel-CC-1678, Siemens-CChiT7070 and ADVA-GE-MUX-1500 successful
– LCAS tests in 4Q 2005

– Based on Riverstone15008 and Alcatel-7750, connected via SDHEquipment (Alcatel-CC 1678) or directly with 10GE-LAN-Phy

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

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
