An approach to evaluate network performance based on hop-by-hop latencies

Understanding network performance especially in link level is becoming increasingly important for network management. This paper puts forward an approach to evaluate network performance based on hop-by-hop latencies from three different levels of granularity including interface granularity, city granularity and AS granularity. We use a set of large scaled traceroute data, from a number of sources which are PlanetLab nodes to other random selected destinations to accomplish the experimental study. The analysis results show that this approach can carry out network performance evaluation in a flexible and effective way.
