In addition to the application of the detailed like e rtisem h dire challenges, since there is no direct relationship between the IP address of a host and its geographic location. nomena to the packet delay. Among these contributions we determine the ones which are related to the geograph-ical distance that the packet traveled. Our model, instead of handling the packet delay as an irreducible unit, decom-poses the overall path-wise packet delay to link-wise com-ponents like the processing delay, propagation delay and even ICMP Echo Reply generation time. In this way we are able to approximate the overall propagation dela
