  In the Future Internet, a multitude of networks will coexist and complement each other. These networks allow specialization but require isolation of functionalities in order to provide dependable and predictable networks. This allows different networks to run in parallel but isolated from each other. Additionally, network resource scalability is supported to reduce the time and overhead required to introduce new services. The objective of the COMCON (COntrol and Management of COexisting Networks) project is to design novel control and management mechanisms that support the coexistence of networks in a future networking scenario and to illustrate the economic advantages. In this contribution we present three use cases defined in COMCON, which serve as a guideline for our virtual network architecture.
