Internet Interaction Pinged and Mapped
J. Quarterman, Smoot Carl-Mitchell, Gretchen Phillips · 1994
We ping approximately 4,500 domains, 1,428 of them in Europe, six times daily, seven days a week. This paper gives an overview of both the techniques of data collection and interpretation of this data with regard to network latencies to selected domains in Europe. It includes a geographic representation of the data that gives new insight into IP networks as they are actually used in real time across time zones, providers, and national boundaries. The heart of the paper is the accompanying maps, which show usage patterns on the Internet in Europe as they cross the continent from east to west. I . Introduction Geographical plotting of latency data obtained by use of ping (ICMP ECHO) permits a perspective view of the relative distance of selected major domains in Europe according to one of the metrics that matter most on the Internet: round trip time. II . The Maps The maps included with this paper show round trip times from our hosts (tic.com) to selected hosts in Europe. They use ave...
