Conference Date / Time
31st Aug 2010 (Tuesday) from 10.00am to 12.00pm AEST (SYD, CBR, MEL)
The current voip service offered by AARNet is based on customers connecting their IP PBX or VoIP Gateways to AARNet Gatekeepers to route IP calls between institutions for free. There is an expectation that the customers know that by connecting to the Gatekeeper they will be able to more easily connect to each other and to AARNet MCUs (for conference calls). Everyone needs to know each other and have access to contact details to communicate and collaborate. There is no support for Instant Messaging or Presence information to check availability to call beforehand.
The current video service offered by AARNet is based on customers connecting their video endpoints to AARNet Gatekeepers or directly to AARNet MCUs to route video calls to a central point for video conferences for free. Customers know that by connecting to AARNet MCUs (for conference calls) that everyone needs to know each other first to distribute the dial in details, or have completed a Quality Assurance test to register the Video endpoint so the MCU can dial out to each endpoint. Customers then have access to communicate and collaborate. There is no support for Instant Messaging or Presence information to check availability to call beforehand.
More recently vendors are developing platforms that are “SIP” protocol compliant to connect vendor islands together however each has interpreted the SIP standard differently making the interoperability aspect challenging. SIP appears to work better for Voice with limited call control features to support than Video. Other vendors have extended their enterprise voip and video platforms to extend to business-to-business capabilities, however these rely on the same platform and are often based on proprietary standards.
Service broker challenge
- No vendor independent platform exists as a directory service for customers and their users to subscribe to.
- Vendor specific platforms for directory services naturally fit to their needs and not other vendors and juggling web browser support and vendor changes to APIs etc can make interoperability a costly exercise.
- Most systems rely on the user knowing who they want to contact beforehand. That is, there is often a lack of searchable attributes which enable an end user to find a person with particular skills, or a researcher in a particular field, etc.
- Some users want to have the ability to control what information is published for security and privacy reasons
- The ability to tie in chat and presence is another level of complexity beyond an opt-in white pages directory area that can extend to a federated directory services solution with metadata to find an expert or researcher you may not know.
The objective behind this Ozeconference is to raise the awareness of this activity item to the group. We wish to gather feedback with regards to whether this work is worthwhile and of value to AARNET connected customers. We do not claim to have all the solutions/answers, but would like to brief the audience on some of the work being done by Keith Duddy (QUT) and a client based solution offered by CCNA (www.ccna.com.au). Together, this work and solutions such as these, may offer a way forward to a suitable solution for the sector.
Speakers:

Agenda
- Describe the Directory Services problem for AARNEt and it’s connected
Institutions. Bill Efthimiou (10 minutes)
- Presentation by Keith
Duddy on work plans for “Services in the Global Service Delivery
Framework”. (10 minutes)
- Presentation by Robbie Krugger
(www.ccna.com.au) outlining the Communications Framework application and
it’s use around disparate directory services. (10 minutes)
- Briefly describe the potential approach for addressing this problem.
Bill Efthimiou. (10 minutes)
- Open discussion with invitees. The
following is no exhaustive list, but some topics of discussion may be:
a.
Does this problem already have a solution?
b. Has it been
attempted before and failed? Why did it fail?
c. Is it worth
solving? Is there a requirement?
d. What are the chances of
success?
e. What are the dependencies for such a solution? Eg,
trust, systems
management/coordination, technical support, database
synchronsation, access to
reliable information sources, etc.
f.
Other items of discussion?
