In an AF queue, the FTP packets are ensured the minimum bandwidth of 64 kbps and
the HTTP packets are ensured the minimum bandwidth of 32 kbps. Voice packets in EF
queues have sending priority. They are ensured the maximum bandwidth of 32 kbps.

3.8.5 Integrated QoS Policy Embedding and LR Configuration Example

I. Network requirements
Figure 3-10 presents a scenario, where:
Hosts on Network A, PC1 and PC2, need to send data to hosts on Network B. PC1
needs to send network performance monitoring data to UDP port 3000 on Server
on Network B in addition.
On 3Com 1, the rate of incoming interface Ethernet 1/0/0 is 10 Mbps, and the rate
of outgoing interface Serial 3/0/0 is 2 Mbps. As the result of this rate discrepancy,
congestion may occur on interface Serial 3/0/0.
It is required that:
When congestion occurs, 256 kbps bandwidth is assured for data transmitted from
Network A to Network B.
The size of network performance monitoring data is limited under CIR rate, 80
kbps. Packets beyond the limit are not dropped directly. Instead, they are sent
marked with the lowest preference to the downstream device.
To ensure smooth transmission, LR does not apply to all data sent from Network A
to Network B but network performance monitoring data.
