Abstract:
This document describes issues associated with providing multi-
tenancy in large data center networks that require an overlay-based
network virtualization approach to addressing them. A key multi-
tenancy requirement is traffic isolation, so that a tenant's traffic
is not visible to any other tenant. This isolation can be achieved
by assigning one or more virtual networks to each tenant such that
traffic within a virtual network is isolated from traffic in other
virtual networks. The primary functionality required is provisioning
virtual networks, associating a virtual machine's virtual network
interface(s) with the appropriate virtual network, and maintaining
that association as the virtual machine is activated, migrated and/or
deactivated. Use of an overlay-based approach enables scalable
deployment on large network infrastructures.
