Objective of the Topology information component
•Provide information concerning– The underlying network topology (IP/AS-Level)
•Add two additional measurement subcomponents.– Active measurement subcomponent
• Traceroute@home: IP-level route traces
•Improve the monitoring capability – Allows applications to query the topology information
component.• TopHat API
5
TopHat: Server methods API
• TopHat Methods for active Measurement – TopHat methods are defined on D3B.1 and D3B.2
6
TopHat and XML-RPC
• Access topology information through TopHat with XML-RPC.– Common library that can be use by several development language as Java, C, perl, python.
11
Mapping IP to AS
• TopHat Server can:
• Translate any traceroute@home hop results with its correspondent ASs
• Store ASs information related to IP: (AS, BGP Prefix, Registry, AS Name)
• Query Team Cymru Whois server (GetIP2AS)
13
Future
• OneLab partners will have full access to TopHat.
• TopHat will run as a continuous service for PlanetLab users.
• New users and contributors are welcome.
