Class of Service (Traffic Prioritization) is an IEEE 802.5
supported feature that lets you select critical applications
for high-priority network access. Class of Service
prioritization allows stations running critical applications
under Windows NT 4.0 or Windows 98 to access network
bandwidth before other stations. The NDIS 4 driver
requests a priority token when the selected applications
transmit data.
The Class of Service feature is disabled by default; if you
want to take advantage of this feature, you must manually
enable it after installing the NDIS 4 driver.
Before Starting Class of Service Configuration
The 3C359 NIC must be installed before you configure
Class of Service. For NIC installation instructions, see
Chapter 2, “Installing the 3C359 NIC.”
The NDIS 4 driver must also be installed before you
configure Class of Service. For installation instructions,
see the earlier sections in this chapter.
Finally, you must also have installed the appropriate
applications that you want to prioritize through Class
of Service configuration.
Enabling Class of Service
The Class of Service feature is disabled by default. To
enable Class of Service in a Windows NT 4.0 environment,
follow these steps:
1 In the Control Panel group, double-click the
3Com Class of Service icon.
The DynamicAccess: Select Adapter window appears
(Figure 4-11).
