Using the traffic management capabilities of your Switch allows your
network traffic to be controlled and prioritized to ensure that high
priority data is transmitted with minimum delay.
The Switch 3226 and Switch 3250 have two features that allow you to
manage the traffic on your network:
■
Traffic Prioritization — Ensures that important data is forwarded
promptly by the Switch without delay. See
“What is Traffic
Prioritization?” below.
■
Rate Limiting — Keeps your core network traffic down by setting a
maximum traffic rate on a port by port basis. See
“Limiting the Rate of
a Port” on page 52 .
What is Traffic
Prioritization?
Traffic prioritization allows high priority data, such as time-sensitive and
system-critical data to be transferred smoothly and with minimal delay
over a network.
Traffic prioritization is most useful for critical applications that require a
high level of service from the network. These could include:
■
Converged network applications — Used by organizations with a
converged network, that is, a network that uses the same
infrastructure for voice and video data and traditional data.
Organizations that require high quality voice and video data
transmission at all times can ensure this by maximizing bandwidth and
providing low latency.
■
Resource planning applications — Used by organizations that
require predictable and reliable access to enterprise resource planning
applications such as SAP.
