Network requirements
As shown in Figure 23, Server sends critical data traffic, Telephone sends voice traffic, and Host A and Host B send non-critical data traffic. On Router, because the rate of incoming interface GigabitEthernet 2/1 is higher than that of outgoing interface Ethernet 1/2, congestion might occur on Ethernet 1/2.
Perform configurations to meet the following requirements:
Critical traffic from Server and Telephone is transmitted preferentially when congestion occurs in the network.
Certain bandwidth is guaranteed for traffic from Host A and Host B to reduce traffic delay.
When congestion deteriorates, packets are dropped based on precedence.
Use WFQ in conjunction with WRED for queue scheduling and packet dropping.
