An integrated wired-wireless testbed for distance learning on networking

This paper addresses a remote testbed for distance learning designed to allow the investigation of various issues related to QoS management in wired/wireless networks used to support real-time applications. Several aspects, such as traffic handling in routers, congestion control and node mobility management, can be experimentally assessed. The testbed comprises various operating modes that the user can select to configure the traffic flows and modify the operational conditions of the network. A peculiarity of the testbed is node mobility support, which allows problems related to handoff and distance to be tackled. The testbed provides for both on-line measurements, through software modules which allow the user to monitor the network while it is operating, and off-line analysis of network behavior through log file inspection
