Evaluating SIP-based VoIP communication quality and network security

With the rapid proliferation of the internet and the continuous optimization of modern communication technologies, Voice over Internet Protocol (VoIP) has undeniably emerged as one of the predominant communication technologies. In the face of numerous known and potential network threats, VoIP endeavors to establish a comprehensive, lightweight, and highly robust security mechanism. In order to enhance the efficiency of analysis within the Quality of Service (QoS) management framework, this paper proposes an approach to evaluate communication quality and network security based on the primary communication protocol in VoIP, namely Session Initiation Protocol (SIP). Furthermore, a conceptual framework for constructing the model is presented. By classifying and extracting feature fields from SIP messages, it becomes possible to gain concrete insights into the status of the VoIP network. Additionally, a VoIP evaluation system is developed, which incorporates network administrator feedback and utilizes the constructed classifier for network assessment. This evaluation methodology holds significant practical significance for both the construction of VoIP security measures and the optimization of QoS mechanisms.
