Components 631These devices would be configured with mappings between classificationrules and service levels as shown in Table 100:Table 100 DiffServ Codepoints and Service LevelsWhen these devices receive packets they can simply examine the DiffServcodepoint field of the packets to determine the service level, rather thanperforming the more complex analysis that they are incapable of.Components The following section describes the principles of traffic prioritization using3Com Network Director.Prioritize NetworkTraffic WizardThe Prioritize Network Traffic Wizard enables you to simplify trafficprioritization configuration on your network without the need tomanually set up classifiers, dropping, queuing and marking.The Prioritize Network Traffic Wizard is launched from Tools > PrioritizeNetwork Traffic.The wizard allows you to select:■ Servers that traffic should be prioritized to and from.■ Servers whose traffic (transmitted or received) should be blocked onyour network.■ Applications whose traffic you would like to prioritize.■ Applications whose traffic should be blocked on your network.In addition, the wizard automatically detects whether or not you have anNBX telephony solution in your network and, if you do, automaticallyselects NBX phone traffic for prioritization.Classification Rule Service LevelTraffic marked with DiffServ codepoint 16 Business Critical Service LevelTraffic marked with DiffServ codepoint 24 CEO’s Service LevelTraffic marked with DiffServ codepoint 46 Voice Service LevelTraffic marked with DiffServ codepoint 0 All Other Traffic Service Level
