OWAMP testing event
The OWAMP testing event was held on 15-22 November 2005, the results are published.
The MOME project invited people to participate in the OWAMP interoperability
event.
The tests were performed remotely between interested parties.
The participation was free.
Below is information that was privided before the event.
Motivation
There are different implementations of the One-Way Active Measurement Protocol OWAMP. Bringing them together and test the interoperability is the main goal of this remote event.
OWAMP is a standard of the IP Performance Measurement IPPM Working Group. Information can be found on http://www.ietf.org/html.charters/ippm-charter.html.
The OWAMP interoperability event aims on the following objectives and benefits:
- Bringing together the involved institutes and researchers
- To show the possibilities of OWAMP
- To improve and debug implementations
- To check the interoperability of implementations
Event Description
The remote OWAMP interoperability event should focus on the possibility to use this protocol over a wide range of active measurement scenarios. The different implementations of the protocol should be tested against each other. Basic measurement infrastructure is provided by MOME. Every partner should provide their own equipment for initiating tests. The partners are invited provide internet access to their OWAMP system.
Test Scenario
Currently known available protocol implementations:
- Internet2 OWAMP Version 1.6f (beta): http://e2epi.internet2.edu/owamp/
- J-OWAMP 1.0: http://www.av.it.pt/jowamp/
4 measurement hosts with the following roles and tools installed are provided. For OWAMP Test-Sessions, the ports UDP 21164-21174 must be used:
- 212.183.10.186 (anc-test.salzburgresearch.at), Salzburg, Austria:
- OWAMP Results database incl. simple web interface
- OWAMP Server @ port 22368 & Session-Receiver (CMToolset 2 using j-owamp)
- NTP (Stratum 2, taking time from a GPS-Receiver host in the same subnet)
- 161.24.3.17 (R03S230P013.ele.ita.cta.br), Sao Paulo, Brazil:
- OWAMP Server @ port 22368 & Session-Receiver (CMToolset 2 using j-owamp)
- NTP (Stratum 2, sync to ntp.cais.rnp.br)
- 152.66.247.72 (malna.tmit.bme.hu), Budapest, Hungary:
- OWAMP Server @ port 22368 & Session-Receiver (CMToolset 2 using j-owamp)
- NTP (Stratum 2, sync to clock1.redhat.com)
- 193.136.92.121 (ares.av.it.pt), Aveiro, Portugal:
- OWAMP Server @ port 22368
- OWAMP Session-Sender (J-OWAMP http://www.av.it.pt/jowamp/)
- OWAMP Session-Receiver (J-OWAMP http://www.av.it.pt/jowamp/)
- NTP (currently unknown)
- User Measurement Point, e.g.:
- OWAMP Session-Sender
- OWAMP Control-Client
- Arbitrary measurement points in the Internet can initiate OWAMP tests from their location by e.g. using Internet2 OWAMP Version 1.6f with the following example command:
- owping -t -c 20 -P 21164-21174 152.66.247.72:22368
...initiates an OWAMP-Test between your local Session-Sender and the Budapest Session-Receiver, sending 20 test packets.
- owping -t -c 20 -P 21164-21174 152.66.247.72:22368
- Note: J-OWAMP Session-Senders and -Receivers cannot communicate with Internet2-OWAMP Servers (and vice versa), because this communication is not standardized in the OWAMP Protocol.
Results from CMToolset 2 Session-Receivers (Sao Paulo, Budapest and Salzburg) are available via a simple web-interface and can be retrieved at:
