Figure 75 Prioritize Network Traffic Wizard - Applications
When a device is configured with the classifier rules for a particular
application only one of the rules needs to match a packet in order for the
packet to be identified as belonging to that application.
■ Prioritized Applications — when you select an application for
prioritization, traffic identified as belonging to that application is
treated as more important than non-prioritized traffic by the
configured devices. This means that the traffic will flow through the
network faster and with less chance of being dropped.
3Com Network Administrator configures devices that are capable of
performing complex application classification to identify traffic as
belonging to an application by creating classifier rules. These classifier
rules are equivalent to the classifier rules that make up the definition
in the wizard. Traffic that matches these classifier rules is also mapped
to the Business Critical service level. See “
3Com Network
Administrator Service Levels” on page 182 for definitions of the
service levels used by 3Com Network Administrator.
When you are configuring 3Com devices that are not capable of
complex application classification, 3Com Network Administrator
configures these devices to identify traffic with the Business Critical
DiffServ codepoint. Traffic that matches this classifier rule is also
mapped to the Business Critical service level.
