The simple program wondershaper fits here very well. Just execute:

sudo wondershaper eth0 1024 1024

It will limit your network bandwidth on the eth0 interface to 1Mbps download and upload rate.

Ubuntu comes with a tool called NetEm. It can control most of the network layer metrics (bandwidth, delay, packetloss). There are tons of tutorials online.

Dummynet is one such tool to do it.

KauNet a tool developed by karlstad university, which can introduce packet level control.
