Network virtualization

Multiple separate applications are to run on a single infrastructure

Flexibility, economy, security—the demands on network infrastructure are getting tougher, and not only for large enterprises. Freelancers and SMEs are also looking for ways to get the best from their data networks. This may mean a range of different applications, or a shared infrastructure for multiple users with guaranteed strict separation.


Virtual networking—known as VLAN—enables networks to be used economically by multiple users. The basic principle: A single physical network provides the basis for multiple logical networks. These then behave as if they are physically separate—a vital aspect for security. At the heart of these virtual networks are the routers, switches, access points and wireless LAN controllers from LANCOM. They ensure continuous virtualization throughout the entire network. The advantage: Enormous cost savings due to the minimization of investment in infrastructure. 

  • Just one network infrastructure—cabled or wireless—for completely secure and separate applications (e.g. test networks, operative networks).
  • Two or more companies share the same physical network (including Internet access)—for example at a start-up center or in technology parks.
  • For example, in medicine: Joint medical practices share a common infrastructure without the risk of confidential patient data falling into the wrong hands.
  • For example, supply chains: Companies create an integrated supply chain by connecting their suppliers directly to their own ERP system—without providing access to other internal resources.
  • For example, guest access accounts: Companies can provide their guests with Internet access via their in-house network—guests have no access the rest of the LAN.
  • For example, in education: Separate networks for teachers/lecturers and pupils/students, ensuring that the latter group has only limited access to faculty resources.
  • For example, in retail: The building's technical systems, the fire alarm system, the ERP system—everything runs on the same physical network. And yet they all remain completely separate.
