The effects of Security mechanisms on VoIP communication
Session
Computer Science and Communication Engineering
Description
Voice over Internet Protocol (VoIP), is being deployed in many companies and institutions. The main factors luring these companies to transition to VoIP are the flexibilities and the cost efficiency. This transition resulted with the new situation were voice and data traffic are being integrated on exiting network infrastructure. However with the deployment of VoIP in the existing networks, the security enforcement of the network directly, has an impact in the quality of the overall VoIP technology. Therefore, in order to ensure the QoS of VoIP there is a need to prioritize the VoIP packets, so the packets do not experience delays or lost during the transmission phase. Based on the problem raised, this paper is targeting various security challenges that are affecting the QoS of VoIP. Further, throughout an experimental approach, the situations are simulated using the OPNET simulation tool, were the results are analyzed aiming to compare various security mechanisms and their impact in QoS for VoIP according to international telecommunication union (ITU) standards.
