About the Visualization |
|
|
Visualization Techniques:
(Technique1): Configuration file specifies pixel location of
polygonal shapes: circle for each router, bar with half arrowhead for
each link.
|
Key Visualization Mappings:
(Mapping1):
11 core Abilene backbone routers are displayed geographically as
labeled circles:
- 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
- CLEV = Cleveland, OH
(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
key.
(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.
