Implementation of VoIP over Malaysian Research and Education Network (MYREN) emulator testbed

Quality of Service (QoS) of a network has become the core research area in a computer communication field. Normally researchers will be using simulation software to carry out their research works. However, it is found that simulation software has its own limitations as it does not really reflect the actual network environment. Thus, most research and development works now are exploiting emulation technology to replicate the real network environment by injecting real traffic into the network model. This paper describes the implementation of an emulator testbed for Voice over Internet Protocol (VoIP) transmitted over the Malaysian Research and Education Network (MYREN). The emulator software used in this paper is known as WAN Emulator (WANem) and it is found that the QoS obtained from the emulator are considered acceptable.
