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
