Abstract
The paper presents the procedure for determining the optimal set of hubs and spokes and thus the collection of tunnels in hub-and-spoke network. The subject of the study was a multi-departmental network, with security of transmission requirement, so DMVPN technology with IPSec-protected tunnels were used. The optimization of the hub/spoke set was intended to improve inter-departmental communication efficiency, which was to be confirmed by the analysis of simulation results. In the simulation studies, the quality of the chosen service (VoIP) was checked for the different structures of tunnel connections. Simulation tests were prepared and implemented in Riverbed Modeler environment.
