Networking… ultima frontiera

 Software Defined Networking (SDN)
 OpenNetworking
 OpenFlow

6. 6
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

7. 7
High level overview of SDN

8. 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
