About the Visualization
(Technique1): Configuration file specifies pixel location of
polygonal shapes: circle for each router, bar with half arrowhead for
Key Visualization Mappings:
11 core Abilene backbone routers are displayed geographically as
STTL = Seattle, WA
SCRM = Sacramento, CA
LOSA = Los Angeles, CA
DENV = Denver, CO
KSCY = Kansas City, MO
HSTN = Houston, TX
IPLS = Indianapolis, IN
ATLA = Atlanta
WASH = Washington, D.C.
NYCM = New York City, NY

(Mapping2): Blue circle indicates router having active links.
Gray circle indicates no active links. Circle is also a hot link to MRTG graphs.
(Mapping3): Link line utilization is colored according to the displayed
(Mapping4): Small box near each link indicates an absolute rate of
traffic in bytes/second.
(Mapping5): Black appearing on any link bar indicates network errors,
and grows logarithmically from base to tip, where the base represents
0.001 percent and the head represents 1 percent errors.
