2. Towards a Carrier Cloud
Flexible networking &
distributed virtual
infrastructure
Legacy apps
Application evolution
in cloud (IaaS)
Legacy apps on Drivers: IaaS including networking
dedicated servers DC based clouds in one package, Tailored multisite
connectivity
Drivers: Server consolidation
economies of scale, pay-per-
use / scale-with-demand

4. Add the network aspect to the equation!
• Satisfying application
requirements for latency
and bandwidth is key.
• Network constraints need
to be by added into the Approach #1: Distribute cloud

6. Taking interoperability into account
Adding network aspects
Approach #2: Assess which

• Assure interoperability, both

Interoperability will be needed in both
cases. There will always be boundaries

control of:
• How to request resources • How to realise/implement
the requested
connectivity
Distributed Infrastructure Services
Link negotiation, protocol
Infrastructure: VMs, Storage &
agreement and setup

10. Final words
• SAIL is about networking
• SAIL also caters for interoperability aspects of
the services and APIs developed
• SAIL will be demonstrating Cloud Networking at
FuNeMS in Berlin in July!
