The utility of characterizing packet loss as a function of packet size in commercial routers

This work presents a test called “sizogram” which characterizes the packet loss vs. packet size behavior of a router. This graph can help us to take some decisions about traffic, e.g. multiplexing or not, the number of samples or frames to be included in a packet, etc. In addition, it can be useful to have a better idea of the internal architecture of the router. Simulations have been carried out using different buffer implementations and sizes, and the results show the usefulness of this test.
