Abstract: | While the traffic matrix is used as basic data for many network planning tasks, it must be recognized that its inference in IP networks is particularly difficult and error prone. This paper discusses the issue of defining representative traffic demands and surveys proposed techniques for directly measuring elements of the traffic matrix or inferring their value from link measurements. |
