Advanced Network Virtualization

Network is a communication infrastructure

that includes

link resources

as well as

processing and storage resources

(routers)

Network Virtualization is not just virtualizing

connectivity (VPN, logical routers), but

virtualizing the infrastructure as a whole

Our objective is to accommodate multiple

diﬀerent networks concurrently

(8)

Advanced Network Virtualization

Meta Architecture to accommodate multiple diﬀerent

network architectures

Enable abstraction of resources

Generate resource-isolated logical networks elastically

Allow programmability for new functionalities

Social Impact

C

Realizing

per-user per-app networks

.

C

Allowing

creation of innovative network functionalities

C

Enabling

seamless migration

of network architectures

C

Accommodating

disruptive network services

(test-bed)

C

Bringing

new network business models

(NaaS).
