            |  | 167 | Things seem to be headed towards architectural experimentation. | 
          
            |  | 168 |  | 
          
            |  | 169 | Three things to investigate: | 
          
            |  | 170 | 1. '''''Radio Resource Management (RRM)''''' : incorporate advertisements somehow, for between controllers | 
          
            |  | 171 | 1. '''''Authentication''''' : A entity that allows/denies a host to tx/rx on a network. This combined with forwarding elements provide a base foundation for collaborative multi-controller networks. | 
          
            |  | 172 | 1. '''''Discovery''''' : Controllers discover and establish links with, other controllers within the control plane, sans explicit configuration, like DHCP. | 
          
            |  | 173 |  | 
          
            |  | 174 | The first two are test cases to add credibility to a architecture like this one. In any case, the syntax for service/capabilities adverts must be defined. |
