634CHAPTER 15: PRIORITIZING NETWORK TRAFFIC

Figure 346 NBX step

When 3Com Network Director automatically selects NBX phone traffic for prioritization, traffic identified as NBX phone traffic is treated as more important than non-prioritized traffic and other prioritized traffic by the configured devices. This means that the phone traffic will flow through the network faster and with less chance of being dropped when compared with any other traffic in your network. This improves the quality of your NBX phone calls and ensures that the quality remains high even when your network is congested.

3Com Network Director configures devices that are capable of performing complex application classification to identify traffic as NBX phone traffic by creating classifier rules. See “3Com Network Director Classifier Rules for NBX Phone Traffic” on page 654 for definitions of the classifier rules used for NBX phone traffic by 3Com Network Director. Traffic that matches these classifier rules is also mapped to the Voice service level. See “3Com Network Director Service Levels” on page 655 for definitions of the service levels used by 3Com Network Director.

When you are configuring 3Com devices that are not capable of complex application classification, 3Com Network Director configures these devices to identify traffic with the Voice DiffServ codepoint. Traffic that matches this classifier rule is also mapped to the Voice service level.
