3Com TokenLink VelocityTM XL PCI Network Interface Card manual Click the Additional Ranges tab

Configuring Class of Service 4-23

5Click the box next to each application that you want to have high-priority network access.

Class of Service divides applications into two network access priority groups:

■High-priority

■Low-priority (normal-priority)

Applications that you select are marked for high-priority network access. Unselected applications are given low-priority (normal-priority) network access.

Based on your selections, the NDIS 4 driver can recognize network traffic as high-priority when that traffic is generated by a chosen application.

6Click OK.

7Restart the computer.

Adding Class of Service Ranges and Protocols

You can add information for Class of Service applications that you want to prioritize but which are not listed on the 3Com Class of Service Setup window (Figure 4-12).

You must specify port or socket ranges as well as the network protocol being used. Obtain the information from the application manufacturer.

The Class of Service network driver uses these ranges to determine whether a packet should be treated as high-priority. If you are not able to obtain the range, you can set the entire range to 0000–9999.

To add the Class of Service ranges and protocols, follow these steps:

1Click the Additional Ranges tab.

The Class of Service Additional Ranges window appears, as shown in Figure 4-13.
