perfsonar development work

[Loukik Kudarimoti <>]

Hello Mario,

You are most welcome to join our perfSONAR effort! The areas that we 
cover in our perfSONAR development are quite diverse. I am hopeful that 
you will be able to find an area/s that interests you and brings 
benefits to you as well as RedCUDI and perfSONAR

To give you a brief introduction, I would like to make use of the 
"developer pack" that Nicolas Simar, the project manager of GEANT2 JRA1, 
has used in the past. If you have any questions please feel free to ask.

You mentioned before that your areas of interest are
* Security
* Network Performance
* Computer Intelligence

As the areas that you have mentioned above are quite broad, we would 
like to know more details about them. To start a discussion on this, I 
can provide you brief information about our work which can be related to 
the above areas.

* Security
** Authentication and Authorization - Any perfSONAR service is a 
resource and many of them need resource protection.(you can find more 
information about perfsonar services using links provided below). For 
example, if we are talking about a service of type Measurement Point 
Service, which is capable of handling Web Service communications with 
clients in order to make measurements, it needs to make sure that it 
doesn't overload any entities on the network because of such 
measurements. Hence there is a need for resource protection. Any 
resource protection requires Authentication of the user and 
Authorization policies and implementation of such policies.

perfSONAR has a strong requirement for mechanisms which can support 
Authentication and Authorization across multiple domains so that users 
of one domain can easily access the resources present in another domain. 
We are planning to use X.509 certificates, SAML and Shibboleth. We are 
working with eduGAIN on this. If you are interested in finding out more 
information about eduGAIN please contact  or Mose 
Manuel Macias ()

** Network Security - I know that GEANT2 JRA2 is working on Network 
related security such as Detection of DoS attacks, Detection of other 
network anomalies, Securing network equipments, Using Reverse Address 
Resolution Protocol, Co-ordination of different Computer Emergency 
Response teams, etc. If you are interested in any of these areas, you 
can find more information by either emailing  or by 
visiting the page: http://www.geant2.net/server/show/nav.755

* Network Monitoring

This is the main area where perfSONAR strong hold. What we try to do is 
build a framework and reference implementations for a multi-domain 
monitoring system. Users from other domains can then be able to make use 
of measurement tools in a different domain in order to get monitoring 
data of interest to them. One of the main objectives of this activity is 
to provide support to end-to-end monitoring.

Our current development efforts can be classified into the following areas:

Measurement Archive Service (MA)- A service which will provide access to 
archives storing measurement data. Examples of measurement archive 
services are RRD Type Measurement Archive and SQL Type Measurement Archive

Measurement Point Service (MP)- A service which will allow measurements 
to be made by users. For example SNMP Type Measurement point service, 
Command Line type Measurement Point Service, BWCTL type MP, etc

Lookup Service (LS) - A service/registry which helps the users in 
finding out available services and capabilities of available services. 
Services advertise themselves with Lookup service so that users can 
discover them.

Topology Service (TopS) - A service providing access to topology related 
information

Resource Protector (RP) - A service which provides a domain level 
resource protection i.e., the service is aware of resource usage at a 
domain level for example

Transformation Service (TS) - A service which can transform data from 
one form to another. For example, Traslations to different xml schemas, 
Measurement data aggregations, etc

We are also working on services which help in Authentication and 
Authorization (was previously called Authentication Service but doing so 
now would be a misnomer now)

* Computer Intelligence

I am not sure if I can associate any of our work very closely with this 
area. Maybe a better understanding of what kind of intelligence you are 
interested in will help us here.


Developer Pack:

1. Communicating

PerfSONAR and GEANT2 JRA1 have several sites containing useful information:

1.1. perfSONAR wiki, www.perfsonar.net 
(http://wiki.perfsonar.net/jra1-wiki/index.php/Main_Page)

1.2  JRA1 working area - 
http://wiki.perfsonar.net/jra1-wiki/index.php/JRA1_Main

- the official documentation oriented towards the outside world:
"Getting started", "Download", "User support", those sections are 
updated once a service is in a good shape to be released. (this section 
is currently under construction).

1.3. Mailing lists and mailing lists archives

You can find Information about all the mailing lists and how to 
subscribe, etc here:
http://wiki.perfsonar.net/jra1-wiki/index.php/PerfSONAR_Contacts

If you have any problems subscribing, please contact Jeff Boote 
().

1.4. Information about meetings and conf calls can be found at
http://wiki.perfsonar.net/jra1-wiki/index.php/PerfSONAR_Events

1.5 Communications and contact information can be found here
http://wiki.perfsonar.net/jra1-wiki/index.php/PerfSONAR_Contacts

2. Working

2.1. If you are plan to do any development

2.1.1 The coding guidelines are available at 
http://monstera.man.poznan.pl/jra1-wiki/index.php/Coding_Standards
2.1.2. You will need to be required to use SVN for any development. You 
can get an a/c on SVN here:
2.1.3. The programming language is Java 1.5
2.1.4. you can use any Integrated Development Environment (such as 
Eclipse, SUN netbeans)
2.1.5. In your particular case, you won't have to deal with SOAP, you 
will deal with XML mostly. (So no strong need to learn SOAP, but a 
overview of SOAP is a good thing).
2.1.6. We are using Junit to automate the test the code done (we have 
recently started to do so).  Panagiotis Louridas <> is 
the person to be contacted to have example and advices on Junit.
2.1.7. Once a service is about to be released, the specification of its 
interface have to be passed onto the test team which will then perform 
functional tests on them before having the code released.
2.1.8. To realise what has to do someone who needs to install perfSONAR, 
we strongly encourage you to install an instance of the MA for RedIRIS 
(please check with Roman Laplacz which one to use and where to find the 
relevant information).

2.10. You can find the document related to the perfSONAR services at:
http://monstera.man.poznan.pl/jra1-wiki/index.php/PerfSONAR_and_JRA1_Resources#perfSONAR_services_related_documents 

http://monstera.man.poznan.pl/jra1-wiki/index.php/Generic_Service_Design_resources 


2.2 If you plan to do anything other than development :)
Usually its just the mailing lists for discussions and all the above URLs

3. How do we work?

3.1. Typically for a new service, we follow the guidelines provided by 
the GFD and the development done. A first discussion happen to get 
ideas. Then the a responsible is nominated to write a strawman proposal 
which will be sent to the mailing list (the answer can take some times 
to come back (2-3 weeks).
The strawman is amended, conf call are scheduled when points need to be 
discussed or decision taken.  The strawman consist of two parts: the 
internals of the service itself and the schema updates (to be discussed 
with Martin Swany).
By order of priorities the following functionalities are implemented: 
the basic of the service itself, scripts to ease the installation, 
script to help with the population of the data, the service registration 
to a lookup, the AA, the resource protection.

3.2. Development of the code, includes Junit tests. The code need to be 
deployed once.

3.3. The test team perform some functional tests on the service (upon 
specification and documentation of the interface).

3.4. The release management team verifies if all the documentation is 
provided, if installation scripts are being provided and if the 
documentation is provided:
a) The services specifications: For developers who need to understand 
how to make their applications compliant with Perfsonar. It will include 
message and message formats and high level interfaces and protocols. -> 
In "developers info"
b) User's guide - For people who will install perfsonar. Sysadmins, 
nocs, users. It will include installation, configuration and use of Java 
Services -> "Getting started" and/or "downloads"

3.5. Release

3.6. Bug fixes

3.7.Additional documentation : Developers guide - For new developers. 
API and it tells how the reference implementation fits together and how 
to extend the Java Reference Implementation -> In "developers info"

I hope this information is sufficient for you to get started. If you 
have any more questions, please feel free to contact us.

Best regards,
Loukik
