JRA1: Future Network

Task4: Current and Potential uses of Virtualization

Y2 Work

Reza Nejabati, University of Essex (JANET)


Objectives of Y2-Y3

Proposal for virtualization service architecture and mechanism

Steps:

– Step 1: for single domain

– Step 2: for multi-domain

Final objective

– 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.

Specify the proof of concept demonstration

Implement a test-case demonstration for the proposed mechanism

Closely collaborate with relevant JRA and SA activity to implement a

pilot virtualization federation mechanism for GN3


Work Plan

Three phases in Y2

Phase 1: Analysis, Framework and definition of existing

virtualization service and user requirement analysis

Phase 2: Virtualization mechanism architectural definition and

proposal

Phase 3 (Y2-Y3): Definition and implementation of a proof of

concept test case and demonstration


Work Plan

Phase 1-Y2 : Analysis, Framework and definition of existing

virtualization service and user requirements analysis

Coordinator GRNET

Task1: Review of new projects (coordinator RENATER)

Task2: User requirements analysis (coordinator HEANET)

Task3: Virtualization risk analysis and drawback analysis (coordinator

Task4: Advanced Virtualization service (coordinator HEANET)


Phase1: Analysis, Framework and definition of

existing virtualization service and user requirements

analysis

analysis

Task2: User requirements analysis (coordinator HEANET)

To further extend scope questionnaire

To collect feedback from GN3 wide NRENs

Task3: Virtualization risk analysis drawback analysis (coordinator

DFN)

Recommendation by project office

– To address potential and possible drawbacks for NREN and

Geant on deploying virtualization technologies




analysis

Task4: Advanced Virtualization service (coordinator HEANET)

Virtualisation is normally at ‘data’ plane

– For instance a slice incorporating network or computing resources

Beside this ‘data’ plane there is an operational management plane

– Operational management plane can be divided with FCAPS

Fault, Configuration, Accounting, Performance and Security ISO (CMIP)/ITU (TMN): http://en.wikipedia.org/wiki/FCAPS

The specific FCAPS aspects are the responsibility of:

– Substrate owner or

– E.g. user can’t or is not allowed to manage (certain hardware related

Faults and/or Accounting)

– User of the slice or

– E.g. user wants/needs to manage (certain Configuration options, internal

slice Accounting/Performance)

– Party representing the user

– E.g. user is not allowed by an institute department (like Security:

firewalling/ACL).

So FCAPS virtualisation needs to be investigated

as an advanced service


Work plan

Phase 2: GN3 virtualization mechanism architectural definition and

proposal

Coordinator UEssex

Task1: Architectural definition, recommendation and possible approach

for single domain NREN virtualization service (Coordinator GARR)


for GN3 core network virtualization service (Coordinator PSNC)


for multi-domain GN3 core network + NREN virtualization service

(Coordinator I2CAT)


Phase 2: GN3 virtualization mechanism architectural

definition and proposal

Virtualization service definition

In the context of network and computing infrastructure, virtualisation is creation of a

virtual version of a physical resource (e.g. network, router, 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

NREN virtualization service

What are virtualization services to be offered by a NREN for GN3

community

– Network virtualization services

– IT virtualization services

GN3 core virtualization service

What are virtualization services to be offered by GN3 core

– Network virtualization services

– IT virtualization services




The possible method for implementing virtualization

For NRENs

– Approach for enabling a NREN to deploy a virtualization Frame

work of its choice

– MANTYCHORE, GEYSERS,…..

– Approach for enabling a NREN to interconnect to

virtualization/experimental facility

– FEDERICA, OFELIA

For GN3 core

– Approach for enabling network virtualization of GEANT core

– Leveraging on Autobahn capabilities,..




NRENs Virtulization

Approach for enabling a NREN to deploy a virtualization Frame

work of its choice

– NREN L3 virtualization: E.g.: MANTYCHORE

– NREN L2 virtualization: E.g.: FEDERICA

– NREN L1 virtualization: E.g.: GEYSERS

– NREN IT virtualization : E.g. FEDERICA

Approach for enabling a NREN to interconnect to

virtualization/experimental facility

– E..g GENI federation approach
