Context (1): Infrastructure as a Service

Convergence of computing andcommunication

Expansion of cloud computing

New models and tools areneeded to help users & serviceproviders to specify, configure,deploy, manage their virtualinfrastructures and theirapplications

Context (2): Network virtualization

⇒ Decouples the physical hardware from the service level ⇒ M-to-N mapping (M “real” resources, N “virtual” resources)⇒ to deliver greater resource/infrastructure utilization and flexibility ⇒ Solid basement for customized « network buildings »

⇒ Parallel networks with customized routing, traffic engineering, protocols…

Scenario description

Execute a distributed application in a virtual infrastructure

Application: NAS benchmark (version 3.3) MPI 7 applications: bt, cg, ep, is, lu, mg, sp

Physical substrate: Grid’5000 platform

Steps: 1 – Create a substrate of virtualized resources 2 – VPXIs specification 3 – VPXIs allocation and deployment 4 – Execution

1) Bootstrap: virtualized substrate creation

Virtualized substrate: VXspace

Underlying physical ICT infrastructure

Virtual infrastructures: VPXI concept

We define a VPXI as a time-limited interconnection of virtual computingresources through a virtual private network

2) VPXI specification

VXDL language Specification of virtual resources sets Specification of virtual topology Specification of time line

Example: Specification of three VPXIs : Same resource set & topology, different link rates

4 virtual resources: VN 1, VN 2, VN 3, VN 4 2 virtual routers: VR 5 and VR 6

Conclusions VXDL is a powerfull language to specify flexible and personalizedvirtual infrastructures (VPXIs)

Execution using the modular HIPerNet framework is straightforwardfor our users. Resource virtualisation & dynamic reconfigurationcomplexity is hidden.

Grid’5000 platform is a powerfull physical underlying infrastructurefor VPXI functionalities, performance’s as well as scalability’sexperiments and demonstrations

More features are beeing integrated in HIPerNet (security, OpenFlowinterface, performance measurement, GUI…)

VPXI can be applied to a large variety of usages (new services testand deployment, high throughput applications…)
