Tech?Update!: VLAN = Virtual Local Area Network
Nowadays company networks are not only connected within a certain location, but can also be interconnected worldwide. For network infrastructures that cover very large geographic areas, VLAN (Virtual Local Area Network) makes sense. Departments and team members can be grouped together into subnets regardless of their physical location, while at the same time regulating network traffic accross the entire network.
However, it is also useful to divide a physical network into VLANs for performance and security reasons. For example, the performance within the LANs can be improved by establishing a VLAN because the broadcast-traffic will not transfer to all ports, but remains only in the corresponding VLAN.
The Dongleserver myUTN-80 supports the use of VLAN. To do this, the VLANs must be known to the UTN server. After this, the USB ports used for forwarding data must be linked to the specified VLANs. VLANs can be used to control access to dongle-protected software. This way, a specified group of network participants can be provided with a certain amount of dongle-protected software licenses.
An example makes the new function of the Dongleservers myUTN-80 clear:
- 6 construction employees have access to 3 dongle-protected CAD software licences.
- 3 accountants have access to dongle-protected accounting software.
Software access is restricted to only authorized users. It is also possible to connect each USB port to only one user at a time.
The VLAN function of Dongleserver myUTN-80 allows an even more secure and more adaptable management of copy-protected software. You receive this new function with the update 14.0.27, which you are able to download here.
