This image is from one of the most
recent versions of NetRadar. It contains measurements to about 40
different points on the Internet. Several interesting areas of
Interest on this map are (a) the loop on the left, (b) the red area on
the left, and (c) the clustered structure on the top right. All of
these patterns are the |

| Here is another visualization from
the same program. Label X is the computer where this map originates.
Point A is a router that is slowing down downstream sites. Point B
shows a similar situation. Point C shows a router at a major peering
point that despite high usage, is working fine. |

This is a map of how Ethernet
segments (the fan shaped clusters) interconnect with other segments
and access points. |
|
| Most communication over the
Internet occurs passes through long strands of routers. This graph
shows how quickly different paths of the Internet can diverge. |

Routing can result in remarkably
circuitous routes to get between two different points. As shown down
on the bottom, latency increases mainly because of congestion, not
distance. |
