Function name:IP ToS ClassificationFunction description:Another QoS function is the application of Layer 3 on network framework. Wefocus on TOS field of IP header. There are three bits in TOS field. We meansbit 5~7 of TOS field that we will use. According to these 3 bits, we couldarrange 8 traffics –0 0 0, 0 0 1, 0 1 0, 0 1 1, 1 0 0, 1 0 1, 1 1 0, 1 1 1. As longas we change bit 5~7 of TOS field of IP header, we will create the 8 trafficpackets we meant before. Moreover, we can set High priority or Low priorityfor each traffic class. For instance, if we let TOS 0 0 0 be high priority and TOS0 0 1 be Low Priority, we sent in the packets that have bit 5~7 of TOS Fieldappears 0 0 0 from the port 2 and the packets that have bit 5~7 of TOS Fieldappears 0 0 1 from the port 3. We let the two kinds of packets be transmittedfor port 1 until the port results in congestion. The result is that the packets willbe dropped partially from the port 3 because the packets that belong to LowPriority.Fig. 3-20Parameter description:Quality of Service (QoS) ToS Configuration:Used for setting up the QoS in Layer 3.Port:User can set up the port (1~24) respectively to let TOS QoS functionwork on them. If you would like to set up all ports at a time, user is alsoallowed to choose “All” in the selection list to simplify the procedure ofconfiguration.68

Bit 0, Bit 1, Bit 2:According to the arrangement of Bit 5 ~ Bit 7 in TOS Field of IP Header,it can form 8 kinds of traffics, including 0 0 0, 0 0 1, 0 1 0, 0 1 1, 1 0 0,1 0 1, 1 1 0 and 1 1 1.Class:8 kinds of traffic as mentioned above, user can set up High Priority orLow Priority for each port respectively.69
