Experimental Testbed
We adopt the Nomor Network Emulator for Application Testing (Neatbox) as our testbed setting to our proposed bandwidth management framework. Neatbox is a fully configurable system which emulates the behavior of a mobile network. Nomor’s application test environment Neatbox for HSPA, WiMAX or LTE is a powerful network emulator designed specifically to develop and test applications and services for future mobile devices. Client-server mobile applications can be tested over the simulated network by connecting through the Neatbox via ethernet. Data between clients and servers pass through the Neatbox and are affected by the behavior of the simulated mobile network. The Neatbox is controlled using a web interface. This interface can be accessed using a web browser on any PC connected to the Neatbox. In a web browser, typing the IP address of the Neatbox, depending on which interface the computer is connected to, will bring up the start page of the Neatbox web interface.The Neatbox allows evaluation of the performance of all types of IP-based multimedia services over different radio access networks in real-time. With the potential to configure system parameters and to define specific scenarios (number of users, kind of traffic, position in the cell, mobility pattern) the Neatbox represents a valuable tool to support development of new protocols and smart application technologies (FEC, SVC, MDC) and to design new applications that maximize end user perception in a mobile network. The protocol emulation is used for modeling the various functions inside the radio protocol stack, such as segmentation, encapsulation, multiplexing, prioritization, scheduling, retransmission, reordering and reassembly. It will be used to implement our proposed bandwidth management framework.
