MAC Based Dynamic VLAN Tagging with OpenFlow for WLAN Access Networks

Many network device vendors are providing a vendor specific VLAN based access solutions for WLAN clients. This applications allows network operators to specify WLAN devices which automatically fall into their department specific networks ans allows them to access their local resources like e.g. printers. The configuration of these VLAN mappings is usually manufacturer specific and depends also on the local VLAN policies. However, the presented OpenFlow approach on the other hand presents a solution to encapsulate this functionality as network application. Thus, an architecture, implementation, and evaluation is presented in order to demonstrate that this particular functionality can be easily realized in an OpenFlow network application.
