We explore the opportunities and design options
enabled by novel SDN and NFV technologies, by re-designing a
dynamic Content Delivery Network (CDN) service. Our system,
named MOSTO, provides performance levels comparable to that
of a regular CDN, but does not require the deployment of a
large distributed infrastructure. In the process of designing the
system, we identify relevant functions that could be integrated in
the future Internet infrastructure. Such functions greatly simplify
the design and effectiveness of services such as MOSTO. We
demonstrate our system using a mixture of simulation, emulation,
testbed experiments and by realizing a proof-of-concept
deployment in a planet-wide commercial cloud system.
