The objective of this research is to explore scalable design alternatives
for an architecture to provide Internet Distance Maps Service (IDMaps).
We call hosts performing distance measurements Tracers. Research
issues on IDMaps include:
- Data Collection:
-
What information should be collected?
-
Distance Estimation:
-
How shall distances be measured?
-
Data Distribution:
-
How shall the information collected by Tracers be distributed?
-
Tracers Deployment:
-
How many Tracers shall be deployed and where to put them?
-
Tracers Coordination:
-
How to determine which Tracer is responsible for measuring
which part of the network?
IDMaps operates on the well known port 1884, as assigned by IANA.
