Paper Survey

• Survey on QoS Management of VoIP
• Proceedings of the 2003 International Conference
  on Computer Networks and Mobile Computing
  (ICCNMC03)
• 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

4
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

5
Whats 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

6
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
