Network virtualization in multi-tenant datacenters

Multi-tenant datacenters represent an extremely challenging networking environment. Tenants want the ability to migrate unmodified workloads from their enterprise networks to service provider datacenters, retaining the same networking configurations of their home network. The service providers must meet these needs without operator intervention while preserving their own operational flexibility and efficiency. Traditional networking approaches have failed to meet these tenant and provider requirements. Responding to this need, we present the design and implementation of a network virtualization solution for multi-tenant datacenters.
