Optimal Migration Contracts in Virtual Networks: Pay-as-You-Come vs Pay-as-You-Go Pricing

Network virtualization realizes the vision of an Internet where resources offered by different stakeholders are used and shared by multiple co-existing virtual networks. The abstraction introduced by network virtualization opens new business opportunities. We expect that in the near future, infrastructure providers (or resource brokers and resellers) will offer flexibly specifiable and on-demand virtual networks over the Internet, similarly to the elastic resources in today’s clouds.
