Flow monitoring (Netflow) Status report 12/10/2006 Alessadro Inzerilli - GARR

General subtask info Design and implement of flow monitoring architecture for JRA1; Integration with perfSonar framework; Partners involved: Surfnet (subtask leader- Hans Trompert), CARNet, GARR, Uninett; All working documents (evaluation reports, test bed specification, design docs,..) on wiki: wiki/index.php/Flow_monitoring. wiki/index.php/Flow_monitoring

Status report Netflow existing tools evaluation:  Collector: nfdump chosen among other tested tools as netflow collector tool for JRA1 flow monitoring infrastructure implementation;  Visualisation/analyser: tools selected for later evaluation: Stager, Nfsen; All evaluation documents on wiki page.

nfdump overview Developed by SWITCH (Peter Haag) ; set of tools to collect and process netflow data; supports all important netflow format versions (v.5, v.7, v.9), supports IPv6; has built-in replaying and anonymization functionalities; has a graphical font-end (Nfsen).

Status report (cont.) Defined overall architecture of flow monitoring infrastructure; Two services in implementation phase:  RRD based Netflow MA;  Netflow Flow Subscription MA; Third service in design phase:  Netflow Selection and Aggregation MA; PerfSonar integration in progress;

Overall architecture (Functional design)

Flow Subscription MA Goal: to implement a Netflow Subscription MA that allows a client to request a live stream of Netflow data that can be processed locally by any standard Netflow collector. Design document on wiki:  wiki/images/4/44/JRA1_Netflow_subscription_MA_- _v0.4.pdf wiki/images/4/44/JRA1_Netflow_subscription_MA_- _v0.4.pdf

Flow Subscription MA Functional design

Flow Subscription MA Implementation status Surfnet implemented a working client-server communication model to setup an encrypted, anonymized and custom filtered flow stream; written in Python; plan to integrate the code with the perfSONAR framework (using the Python Ping MP code as an example); first draft of the XML schema's for communication, provided by Martin and Jason, available.

RRD Netflow MA Goal: to implement RRD MA that allows to publish flow-specific information; Metrics published at the moment: flows/sec, packets/sec, bytes/sec; RRD data files provided by Nfsen tool (graphical front-end of Nfdump); Possibility to extend metrics (es. AS matrix, network prefix, protocols).

RRD Netflow MA implementation status CARNet works on two versions of MA  Python version  Java version Python version of MA available at mon3.srce.hr:8090/ mon3.srce.hr:8090/ Java version soon available at wiki/index.php/RRD_type_MA_Service_Installat ions wiki/index.php/RRD_type_MA_Service_Installat ions

Y3 Action Plan Netflow Subscription MA  Implementation of basic functionalities (server/client applications);  Integration with perfSonar framework; Netflow RRD MA  Implementation of basic functionalities;  Client application and LS communication; Implementation of Netflow Selection and Aggregation MA  Design;  Implementation of RRD MA basic functionalities; Netflow visualization  Report on existing tools (Nfsen, Stager);  Web based query front-end on top of Netflow Selection and Aggregation MA; Integration with AA infrastructure; Anonymization; Deployment of software on three test bed boxes (Carnet, Garr, Surfnet).
