Chapter 5. Implementing Quality of Service


This chapter covers the following topics:

  • Introduction to QoS

  • QoS Tool Chest: Understanding the Mechanisms

  • Building the Policy Framework

  • IP/VPN QoS Strategy

  • Identification of Traffic

  • QoS requirements for Voice, Video, and Data

  • The LAN Edge: L2 Configurations

  • Case Study: QoS in the Acme, Inc. Network

  • QoS Reporting

This chapter's objectives are to define the options and technical implementations for the various types of quality of service (QoS) required by enterprises for typical virtual private network (VPN) deployments. Service providers and enterprises typically build parallel networks to support the transport of data, voice, video, and mission-critical and non-mission-critical applications. With the move toward convergence, as well as the use of packet-based IP networks, the shift from circuit-switched division and parallel builds of network resources toward a single IP network is increasing. This chapter covers the requirements for supporting the converged world of Multiprotocol Label Switching (MPLS) VPNs and how this maps to QoS policy applicable in the enterprise. The aim is to provide a deployable set of policies that the enterprise can use as guidelines. You'll also see how to address these policies to the service provider. Specifically, the QoS needs of Acme, Inc. are addressed in the case study.
