Access GridTM (AG)

• Developed by Future Technology at ANL
• Internet based model for video conferencing
  focusing on group to group interactions across
  the grid using various resources
• Multimedia displays
• Presentation and Interactive environment
• Text Chat
• Used for large-scale distributed meetings,
  collaborative work sessions, seminars, lectures,
  tutorials and trainings

Jabber

• Set of streaming XML protocols (XMPP Extensible
  Messaging and Presence Protocol) and technologies
  that enable any two entities on the Internet to
  exchange messages, presence, and other structured
  information in close to real time.
• Instant Messaging (IM) that offers functionality
  similar to legacy IM services such as Yahoo, MSN,
  ICQ, AOL.

Jabber in Access Grid

• Venue Client is used to connect and participate
  in an Access Grid virtual venue
• AG text client in a Venue Client is used to
  communicate between users across AG nodes, but
  not able to communicate with other non-AG users.
• Replaced AG text client with jabber chat client
  and connecting to our DSD Jabber Server
• Users can use their existing jabber id and
  password or register one in DSD jabber server
  using AG User profile dialog

Continuation

• All Users in AG, enter into the jabber chat when
  they start the Venue Client.
• For each Venue, a chat room is created in the
  jabber server for group interactions
• Users join various chat rooms corresponding to
  the venue they are in the AG

Why Jabber in AG?

• Non-AG Users able to communicate with other AG
  users and get involved in the discussion using
  other jabber clients like Gaim, Exodus, etc.
• Jabber is secure. Any server can be isolated from
  the public jabber server and robust security
  using SASL and TLS has been built into the core
  XMPP technologies.
• User in a jabber server can interact with another
  user in different Jabber server

Future Work

• Inviting the non-AG users from Venue Client
  directly
• Sending graphics messages (smiley)
• Transferring the files to non-AG users
