3.8.3 CQ Configuration Example

I. Network requirements
In the following diagram, Router A and Router B are connected back-to-back using a
PPP link. Use the PC attached to Router A as FTP and HTTP Server and the PC
attached to Router B as FTP and HTTP Client. Configure the routers to have traffic
forwarded from Router A to Router B.
Before configuring the routers, make sure to:
Set up a PPP connection between Router A and Router B, and an FTP connection
between the two PCs.
On the client PC, FTP and HTTP large files from the FTP and HTTP server
attached to Router A at the same time.
Customize the FTP and HTTP traffic to share link bandwidth in the ratio of 1 to 2.
