Advanced Network Services for (LHC) Experiments
Time 01/16/13 10:40AM-11:00AM
Recent years have seen a dramatic evolution in the area of research and education networking, enabling faster data rates and novel services to user communities. The NSF-funded ANSE project
integrates these new services, in particular dynamic bandwidth allocation (DYNES) and real-time network performance monitoring (perfSONAR), with the higher level workload management software deployed for the Large Hadron Collider (LHC),
like PanDA and PhEDEx in the ATLAS and CMS experiments.
A software defined networking approach, and in particular the use of dynamic bandwidth allocation capability, already available in ESnet and Internet2 networks, makes the network a
truly manageable resource, on par with CPU and storage resources.
The target is smart optimization of resource utilization through co-scheduling and deadline scheduling algorithms within data and workload management systems.
The ANSE system reacts to real-time conditions such as network events or node failure, as well as usage specific parameters like changes in data distribution priorities.
While the primary target for ANSE are the LHC experiments, the project's approach, is clearly applicable to other distributed computing and data intensive science applications on global scale.
