If network is busy, packet buffers will be full and routers will start dropping packets. So, you may probably test by dropping outgoing packets matching a certain src/dest IP/port with a firewall, such as iptables on Linux.

By the way, I just browse the Linux kernel configuration and it has a packet generator for network stress testing!
