WISDOM - Wide In Silico Docking On Malaria
WISDOM consists of virtual screening techniques AutoDock and FlexX. both are in silico docking techniques, where researchers use large computing power (Grid systems) to compute the probability that potential drugs will dock with a target protein. Distribution of high volume input data from the specified Input data Server High bandwidth need and low latency for data distribution of up to 240 GB
KoDaVis –Making Atmospheric Processes visible
Simulations of physical and chemical processes in the atmosphere help to understand the effect of human activities on the climate: data sets ~ 1000 GigaByte stored on 1 or more central servers Collaborative visualization of data provides insight into processes
TOPS - Technology for Optical Pixel Streaming
Streaming of high resolution 2D scientific content Huge data source (~50 TB), not practical to transfer data itself Interactive queries on data source. Results (images) are streamed to scientist for analysis Visualisation of huge data-sets on a tiled panel display (TPD). The rendering is performed at a source node Requirements: 10 Gbit/s, 100 msec latency, layer 2, MTU 9000
DDSS – Distributed Data Storage System
Huge data volumes moved over the network in parallel TCP/IP streams Transfers both latency- and bandwidth-dependent Single network links allocation for one-to-one scenarios
Key points:
Hierarchical architecture for the Network Service Plane (NSP)
independent entities (Inter Domain Brokers)
Interface common for the adaptation layer and the network service plane
Authentication (AuthN) and Authorisation (AuthZ) Infrastructure based on the Generalised AAA Toolkit [1].
AuthN

given path to a common bandwidth level. First, it chooses the min-max bandwidth following user’s constratins. In the second step, the highest bandwidths are reduced according to the technology-induced granularity until the smallest bandwidth is equal to or greater than the min- max bandwidth.
malleable reservation request.
Key points:
internals of HG allow stateful or stateless interoperability, depending on HG implementation

design, using IDC)
1. IDB in Harmony receives reservation request. 2. IDC is seen as a simple domain (limited IDB –request forwarding-) 3. Reservation request to IDC domain is sent to the Gateway 4. Gateway translates request from Harmony to IDC and initiates the reservation procedure in IDC control plane.
