= IMF GEC10 QSR = ---- = Draft Draft Draft = ---- = Overview = This wiki page serves as the Status Report following GEC10 for the IMF project. * Draft created by Rudra Dutta on March 22, 2011 * Modified by Rudra Dutta March 22 - April ? 2011 * Final version released April ? 2011 Upon consultation with GPO, the priorities of the project were revisited for Year 2 of this project. As a result, Year 2 (Spiral 3) goals were focused on integrating the developed IMF capabilities for measurement, and transfer of measurement (from substrate to in-slice stack), with existing GENI Inst&Meas capabilities; specifically, to integrate and install perfSONAR (pS) MPs and archives to collect performance measurement data from Polatis switches and Infinera DWDM platforms on 4 BEN sites, and (subsequently) integrate pS MP polling, or adopt other GENI I&M capabilities, into IMF to mediate the ability of in-slice reactive protocols to communicate back to actuators in the substrate. At GEC10, the first of these (collecting performance data from Polatis using pS) capability has been completed. This leverages Spiral 3 goals of the ERM project team, who also form the Columbia U part of the IMF team. In order to achieve this, the main effort was to collaborate with the perfSONAR development team to define a modified form of the pS client, which we embed in the IMFRealTime service, to allow the measurement to be obtained by the in-slice software; additionally, to create a pS Measurement Archive in which measurements from the substrate optical switches could be made available for the client. The latter part has also been successfully integrated into the universal ERM box by the Columbia team, as part of the ERM project. This is running on 6 of the 8 switches of the BEN testbed in North Carolina, and the IMF capability to query the pS archive serving those switches was demonstrated at GEC10.

We have previously collaborated with the GENI LEARN project team, and progressing toward deploying IMF in LEARN. == Collaborations == The IMF team continued to collaborate with Deniz Gurkan of the GENI project LEARN. The IMF team collaborated with Martin Swany of the perfSONAR team to define and discuss the requirements of IMF as a pS usecase, resulting in the articulation of an alternate type of pS client and functionality, one that more nearly matches the needs of real-time oriented systems such as IMF. == Other contributions == None. = Code Release = == Documentation and Release Notes == The GEC10 version of the IMF system can be built from source in the following tarballs: * [attachment:mh.tar.gz Measurement Handler] * [attachment:pubsub_for_perfsonar.tar.gz !PubSub for PerfSONAR] * [attachment:perfsonar_imf_realtime.tar.gz PerfSONAR IMF Realtime service] ...
