DiffservNetwork

network

This network contains a router with an 10Mbps Ethernet interface, and with a 128kbps dialup connection to a server.

The dialup connection is the bottleneck of the traffic from the clients to the server. Without QoS, high traffic can cause random packet drops at the router Ppp interface.
