Paper Survey “Survey on QoS Management of VoIP” Proceedings of the 2003 International Conference on Computer Networks and Mobile Computing (ICCNMC’03) Xiuzhong Chen, Chunfeng Wang, Dong Xuan, Zhongcheng Li, Yinghua Min and Wei Zhao

Topics The authors divide the system into two management planes: Data Plane Packet Classifier Buffer Management Scheduling Loss Recovery Error Concealment Control Plane Admission Control Resource Provisioning Traffic Engineering Connection Management

The Facts IP network is resource-shared as compared to resource-dedicated PSTN IP-based VoIP applications are cost-efficient IP networks are based on best-effort services IP networks are lacking of QoS control capability Packet loss, delay and delay jitter may occur

What’s In It? Packet Classifier is discussed Buffer Management and Scheduler are discussed Packet Loss Recovery and Error Concealment are discussed Parameter-based and Measurement-based Admission Control is discussed

However… Signaling protocol not covered Multi-level VoIP services not considered More mechanisms in data plane and control plane could be discussed Flow-based Classifier and Scheduler Bandwidth Broker Inter-domain QoS Provisioning … We will try our best to inspect them
