4. Virtual Infrastructure

5. Infrastructure Virtualization Definition
In the context of network and computing infrastructure, virtualisation is creation of a virtual version of a physical resource (e.g. network, router, switch, optical device or computing server), based on an abstract model of that which is often achieved by partitioning (slicing) and/or aggregation.
A virtual infrastructure is a set of virtual resources interconnected together and managed by a single administrative entity.

6. Motivation for Infrastructure Virtualization
New era of bandwidth demand
New network-based application with large bandwidth requirements

It is not feasible nor scalable for network operators to setup and configure dedicated network for each application type or category

7. Motivation for Infrastructure Virtualization
Future Internet providers and operators
deployment of dynamic infrastructures capable of supporting all application types, each with their own access and network resource usage patterns

Infrastructure virtualization and slicing is key enabler for Infrastructure As A Service (IaaS)addressing this issue

8. Research on Infrastructure Virtualization in GÉANT3
Research activity
GÉANT3-JRA1-Task4 research activity
Analyze the current available solutions suitable for NREN and GÉANT infrastructure virtualization and possible use of them
Virtualization of network and IT resources
Network node and transport service virtualization
Virtualization of computing resources
Virtualization in multi-domain environment
Creating a single virtual domain comprising resources from multiple domain

9. Research on Infrastructure Virtualization in GÉANT3
The European research community has managed to achieve significant progress on infrastructure virtualisation technologies through several new and on-going research projects
Requirements for virtualization service is different for each NREN and not exactly defined
We don't intend to propose or develop yet another virtualization technology or mechanism
We aim to build ’ GÉANT virtualisation service based on the developments and achievements of EU projects
Enabling Interoperability and federation between the existing European virtualization mechanisms to achieve a virtualization mechanism for GEANT and associated NREN capable of supporting multi-domain, multi-layer, multi vendor, multi technology.

10. Existing Virtualization Frameworks
Analysis of frameworks and definition of existing virtualization services
A comprehensive comparison study of major existing virtualization frameworks
GENI : SFA framework and architecture
AKARI: multilayer multi-technology virtualization
Panlab/Planetlab: Teagle framework and architecture (service+ SW based network node)
NOVI: an SFA based Virtual infrastructure creation and federation mechanism
SAIL: Self-managed virtual network (L2/L3), fully integratedwith cloud
GEYSERS: Layer 1 , IT (computing/Storage) virtualization
OFELIA: Layer1 , layer 2 , IT (computing/Storage /virtualization
MANTYCHORE: Layer 3,layer 2 virtualization
Phosphurus: Layer 1 virtualization
Federica:Layer 1 , IT (computing/Storage) virtualization
A sample commercial (Amazon & Google)

11. Comparison Study

12. User Requirement Analysis
Findings analysis indicates:
Mainly interested on network virtualization
Sever virtualization is considered mature enough
The timescales over which NRENs expect to deploy these services range from 2012
Requirement for virtualisation in a multidomain environment
Requirement for a federated virtualization environment
NRENs expressed an interest in layer 2 Layer 1 and layer 3 service virtualisation.
Little interest in server.

13. Lesson learned so far
The current virtualisation technologies resulting from the existing projects and framework are still in their research and development stage. It is therefore not realistic to propose a specific virtualisation technology solution to the NREN and GÉANT community.
We Proposes an integrated architectural approach that allows the different virtualisation technologies deployed across the NRENs and GÉANT to be integrated, offering a multi-domain, multi-layer and multi-technology virtualisation service
This approach enables each NREN to adopt one or multiple virtualisation technologies, depending on their requirements, and to offer to its users inter- and/or intra- domain as well as multi-layer infrastructure virtualisation services.

14. GENUS (GÉaNt virtUalization Service)
GENUS architecture is a multi-layer, multi-domain and multi-technology virtualization architecture suitable for NREN and GÉANT requirements
GENUS is not a virtualization mechanism or framework. It leverages on virtualization frameworks, mechanisms, tools and software already implemented within various EU projects and initiatives as well as GÉANT bandwidth on demand provisioning system (Autobahn)
GNUS requires NRENs to adopt an existing virtualization mechanism. The choice of virtualization framework and mechanism is up to each NREN based on their requirements and constrains
NRENs and GÉANT backbone network are the infrastructure providers of GENUS and GENUS itself has no resources.
