What’s the problem ?

The internet is the problem But Why ?

well it Was designed 30 years ago .

Difficult to adopt a new architecture

Difficult to Modify that architecture

3

Network virtualization to the rescue.

what we expect from NV.

Main Idea is .

test new architectures

help in the innovation of new techno’s

NV= {V.Nodes,V.Links} / NV ∈ Physical Net = {NV1,NV2,...NVn}

NV propose that ISP InPs

SPs

InPS manage the infrastructure SPs create the and manage the VN

4

characteristics of NV

NVs heterogeneous techno’s

share the same physical infra

run in isolation of each other

5

NV

start to see this concept in different techs like Vlans

VPNs

Programmable Networks like SDN isolate run conflicting code

Overlay Networks

distributed systems such as cloud computing, peer-to-peer networks, andclient-serve

6

NETWORK VIRTUALIZATION PROJECTS

Networking technology (X-bone) Layer of virtualization (1->7 ) the lower it is, the higher the exibility

Architectural domain

Granularity of virtualization

Overlay Networks

distributed systems such as cloud computing, peer-to-peer networks, andclient-serve

7

Trends

Trends

not just focus on solving one problem

pushing virtualization to lower layers

bridging gaps between diverse technologies.

8

Design Goals

Flexibility and Heterogeneity.

Manageability .

the lower the layer = more flexibility (less payload in vpns )

independence on specific technologie (not over IP)

eas in the management of the virtual resources .

Isolation

Isolation between coexisting VNs to provide security, privacy, and fault-tolerance .

29

Design Goals

Programmability.

Experimental and Deployment Facility.

enabling a secure programming paradigm

Legacy Support

11

A lost of research need to be done

signaling and bootstrapping

resource allocation

resource discovery

Dynamism and Mobility ManagementSecurity and Privacy

12

A lost of research need to be done

we need new internet

NV will be in the architecture
