2. Managerial Issues
This meeting
With the advent of the BAR and NPM weekly meetings, this meeting has no function any more. It
is thereby adjourned, and all the actions are routed to the corresponding weekly meetings.
3. Progress update
Network Performance Monitoring
MJRA4.3
(T1.4)
3/Sep
Prototype
Partners:
“Development and Integration of Interfaces” (S-T1.4.2)
UCL, DANTE
Leading: Paul / Yee / Loukik /
and Mark
This milestone is the development of the software prototype for network performance
monitoring. Closely working with DJRA4.2, it will develop the software to make sure
what it has been specified in DJRA4.2 works.
The main goal of this milestone is to produce a web service with a wsdl document that
describes how a network domain can publish (using the nm-wg schemas) the
performance metrics gathered in the network itself. Initially this web service will work
with a single product like WP7 software, but part of the goal is to make possible that
other products like gridmon or pipes can use the same web service.
Once the web service is done, should start the process to interface with R-GMA, so
XML schemas talking to SQL.
07/Jan
KK will organise a phone-conference to discuss priorities and features for the next
prototype, due 31/03
21/Jan
Phone conference took place on 19/Jan. The priority is with the deployment of the
EDG::WP7. Development work will focus on data aggregation/merging and also
security. KK to circulate minutes within the day.
25/Feb
Phone conference took place on 23/Feb. Workplan validated and time estimates
provided; exception is the deployment, which is very difficult to estimate as it is
unknown, experimental and partly depends on JRA1. JRA1 will not be able to provide
secondary producer as initially planned, through lack of computing resources. We will
only have the one, hosted by CNRS. However, one of the two sites of the JRA1 gLite
prototype already joined our end-to-end monitoring ring.
KK pushed AKP’s security document to JRA3 for comments.

12/Nov
Leading:
The next activity is a prototype, due end of January. However, BAR is currently
understaffed. The main thrust for November and perhaps December will go towards the
architecture, fuelled by the Den Haag meeting.
03/Dec
CJP:
Produced a straw man BAR architecture document and sent it to the BAR team.
Prepared and delivered a presentation on BAR at the Hague meeting.
Had a meeting with Anand to discuss the way forward with the BAR prototype. It is
decided that I should write an XML schema to describe the BAR interface and Anand
should write one for the NSAP interface. These are to be ready by beginning of January.
Once this is ready, dummy BAR service and NSAP service to be produced and deployed
by end of January. We also discussed how HLM request parameters can be used to
work out BAR-NSAP request parameters.
17/Dec
CJP produced a draft architecture document. There is also a plan to produce a nonfunctional, but complete prototype as follows:
- DANTE update interfaces in DJRA4.1 by 24 Dec
- DANTE produce BAR NSAP schema by 15 Jan
- CJP develops a basic BAR service for 31 Jan
- DANTE produce dummy NSAP for 31 Jan
The activity is short-staffed and the workplan is obsolete anymore.
21/Jan
CJP:
- Browsed WS-I Basic profile 1.0. This is the version that JRA1 has recommended in
using when developing Web Services for EGEE.
- Started building the software development platform
25/Feb
On course for BAR and North side of WS for end of Feb non-functional prototype.
Small problems with NSAP WSDL and stubs.
KK pushed AKP’s security document to JRA3 for comments.

“Specification of end-to-end bandwidth reservation Partners: UEDIN / DANTE /
system” (S-T2.1.4)

Leading:
CJP is drafting an architecture document. Architecture taskforce will be constituted
during/after forthcoming phone conference.
We don’t know about progress with the interfaces update, as Anand is away.

Minutes
EGEE-JRA4-ALLConference call
- wrote minutes and circulated to JRA4
- Updated and released the BAR architecure document
- Added requirements
- Added examples of BAR-NSAP request mapping
- Updated the architures diagram
- Removed all references to NE
21/Jan
CJP:
- Browsed WS-I Basic profile 1.0. This is the version that JRA1 has recommended in
using when developing Web Services for EGEE.
- Installed and tested Axis 1.1 on Tomcat 5.5.4
- Updated the BAR architecture document following EPCC Technical Reviewers
comments and some details that became clear from reading various EGEE documents.
- Wrote an incomplete first draft of a deployment scenario for BAR and NSAP services
on EGEE infrastructure. This scenario is to be used for demonstration purpose.
25/Feb
Architecture in the background. WS-Agreement currently looks very distant.
