Federating experimental platforms as a playground for the future internet
The document discusses federating experimental platforms as a playground for the future internet. It describes past successes with testbeds and outlines challenges in reproducing experiments across multiple testbeds. The target of federation is to allow experiments to run seamlessly across different testbed facilities through the sharing of resources, user credentials, and resource descriptions. Key aspects of federation include policies, monitoring, and security across distributed testbed resources.

Or check the robustness of your assumptions? ● Which Solution(s)? Simulation, Emulation, Testbeds ● A testbed for what type of problem? One or multiple testbeds? ● What about the environment?

- 13. Architecture: Definition (fromGENI) ● An aggregate represents a resource or set of resources that can be offered for inclusion in some customer specified topology. These typically fall into the broad categories of Computation, Communication and Storage resources. ● A sliver is a (real or virtual) resource group provided by the aggregate via the “Aggregate Manager” (AM) API. ● A slice is a collection of slivers gathered for a common purpose that are configured into a topology on which to deploy experiments or applications in some degree of isolation from other slices.

PlanetLab Terminology ● Site A site is a physical location where PlanetLab nodes are located (e.g. Fraunhofer Institute or UCL). ● Node A node is a dedicated server that runs components of PlanetLab services. ● Slice A slice is a set of allocated resources distributed across PlanetLab. Slices are assigned to some number of PlanetLab nodes. Slices have a finite lifetime and must be periodically renewed to remain valid. ● Sliver A sliver is a slice running on a specific node. You can use ssh to login to a sliver on a specific node. ● MyPLC: PL control framework 19 FIBRE Workshop- Salvador - Nov 27 2012 19
- 20. Distributed Virtualization ● As a user you want to isolated from other activities on those nodes on which you run. The PL provides a level of isolation which gives you your own file system, and process control. ● You share CPU cycles and network bandwidth with other active slivers on each node. ● The concept of slice aggregates the presence of your slivers within the system 20 FIBRE Workshop- Salvador - Nov 27 2012 20
