Chapter 10 Quality of Service (QoS) Table 47 Queue Setup: Add (continued) LABEL DESCRIPTION Weight Select the weight (from 1 to 8) of this queue. Buffer Management Rate Limit Cancel OK If two queues have the same priority level, the Zyxel Device divides the bandwidth across the queues according to their weights. Queues with larger weights get more bandwidth than queues with smaller weights. This field displays Drop Tail (DT). Drop Tail (DT) is a simple queue management algorithm that allows the Zyxel Device buffer to accept as many packets as it can until it is full. Once the buffer is full, new packets that arrive are dropped until there is space in the buffer again (packets are transmitted out of it). Specify the maximum transmission rate (in Kbps) allowed for traffic on this queue. If you enter 0 here, this means there's no rate limit on this queue. Click Cancel to exit this screen without saving. Click OK to save your changes. 10.5 QoS Classification Setup Use this screen to add, edit or delete QoS classifiers. A classifier groups traffic into data flows according to specific criteria such as the source address, destination address, source port number, destination port number or incoming interface. For example, you can configure a classifier to select traffic from the same protocol port (such as Telnet) to form a flow. You can give different priorities to traffic that the Zyxel Device forwards through the WAN interface. Give high priority to voice and video to make them run more smoothly. Similarly, give low priority to many large file downloads so that they do not reduce the quality of other applications. Click Network Setting > QoS > Classification Setup to open the following screen. Figure 86 Network Setting > QoS > Classification Setup The following table describes the labels in this screen. Table 48 Network Setting > QoS > Classification Setup LABEL DESCRIPTION Add New Classification Click this to create a new classifier. Order This is the index number of the entry. The classifiers are applied in order of their numbering. Status This field displays whether the classifier is active or not. A yellow bulb signifies that this classifier is active. A gray bulb signifies that this classifier is not active. Class Name This is the name of the classifier. Classification Criteria This shows criteria specified in this classifier, for example the interface from which traffic of this class should come and the source MAC address of traffic that matches this classifier.
