Hi,

At slide 2,
it says that the service provider is data centers provider, ISPs, Mobile virtual network operators.
My understanding is that they are customers of virtual network provider, not service provider.

Refer to the following paper.
IEEE COMMUNICATIONS SURVEYS & TUTORIALS, VOL. 15, NO. 4, FOURTH QUARTER 2013
Virtual Network Embedding: A Survey
Andreas Fischer

It depicts that future Internet architecture decouples
the role of current Internet Service Providers(ISPs) into two new roles: 
The Infrastructure Provider(InP) who deploys and maintains the network equipment and the Service Provider (SP), in charge of deploying network protocols and offer end to-end services.
So the role of the service provider is segmented into virtual network provider, virtual network operator, service provider, where the service provider is to offer virtual network services.
Therefore, the service provider used in the ppt. is a network operator
based on virtual networks.

Please, let me know if my understanding is wrong.

Sincerely yours,
