Providing Differentiated Services on a Router

To provide true differentiated services, you must include a Diffserv-aware router in your network topology, as described in Hardware Strategies for the Diffserv Network. The actual steps for configuring Diffserv on a router and updating that router's files are outside the scope of this guide.

This section gives general steps for coordinating the forwarding information among various IPQoS-enabled systems on the network and the Diffserv router.

How to Configure a Router on an IPQoS-Enabled Network

The next procedure uses as its example the topology in Figure 2-4.

Before You Begin

The next procedure assumes that you have already configured the IPQoS systems on your network by performing the previous tasks in this chapter.

  1. Review the configuration files for all IPQoS-enabled systems on your network.
  2. Identify each codepoint that is used in the QoS various policies.

    List the codepoints, and the systems and classes, to which the codepoints apply. The next table can illustrate areas where you might have used the same codepoint. This practice is acceptable. However, you should provide other criteria in the IPQoS configuration file, such as a precedence selector, to determine the precedence of identically marked classes.

    For example, for the sample network that is used in the procedures throughout this chapter, you might construct the following codepoint table.


    System
    Class
    PHB
    DS Codepoint
    Goldweb
    video
    EF
    46 (101110)
    Goldweb
    goldweb
    AF11
    10 (001010)
    Userweb
    webout
    AF12
    12 ( 001100)
    BigAPPS
    smtp
    AF13
    14 ( 001110)
    BigAPPS
    news
    AF18
    18 ( 010010)
    BigAPPS
    ftp conformant traffic
    AF22
    20 ( 010100)
    BigAPPS
    ftp nonconformant traffic
    AF31
    26 ( 011010)
  3. Add the codepoints from your network's IPQoS configuration files to the appropriate files on the Diffserv router.

    The codepoints that you supply should help to configure the router's Diffserv scheduling mechanism. Refer to the router manufacturer's documentation and web sites for instructions.
