Alcune possibili definizioni

SDN’s “reason for being” was the “separation of control and data

[and] centralization of control and programmability”

• OpenFlow è un possibile protocollo tra control e data plane

NFV’s purpose was the “relocation of network functions from

dedicated appliances to generic servers”

NV is an overlay; it’s a tunnel. Rather than physically connecting

two domains in a network, NV creates a tunnel through the existing

network to connect two domains.

In contrast to SDN, in which hardware remains the driving force,

VMware network virtualization technology truly decouples network

resources from underlying hardware.

• Virtualization principles are applied to physical network infrastructure,

abstracting network services to create a flexible pool of transport capacity that

can be allocated, utilized and repurposed on demand

High level overview of SDN

8

Network Virtualization

Ability to run multiple virtual networks that:

• Each has a separate control and data plane

• Coexist together on top of one physical network

• Can be managed by individual parties that potentially don’t trust each other
