In today’s economic climate, efficiency has become a key aspect of building networks, and operators are looking for the minimum amount of over-provisioning to meet QoS requirements. In this presentation, we analyze backbone traffic traces at different timescales. After showing that the aggregated traffic is well behaved, we present a methodology and simple empirical rule for capacity allocation on backbone links. In this manner, we demonstrate that some rules of thumb, such as a maximum link load of 50%, might not be acceptable approaches any more.
