Conference call signaling design

MUC (XEP 045)

• Manual
• Multi-user-text chat in the context of a room or channel
• Advanced features such as invitations, room moderation and administration
• each room identified as a room JID (room_name@hostname)
• each occupant room_name@hostname/nick
  • nick is the room nickname of the occupant
• a user enters a room by sending directed presence to the room_name@hostname/newnick
• messages addressed to the room itself
• a user exits the room by sending presence of type 'unavailable' to room_name@hostname/nick
• should be developed on the server, we can demo just with this one (place all of the info in the body)

Jingle (XEP 0166)

• Manual
• as far as I can tell, just some logging and forward everything to the client
• "a proper way" to exchange the signalling metadata

Multiparty Jingle (XEP 0272)

• Manual
• a combination of MUC and Jingle
• we need this in order to have a conference call using Jingle

Client's functionality

Workflow

• create an account (XEP-0077)
  • at the moment there is no xmpp extension allowing for guest users
  • I think the most straightforward way is for client to supply random data to the server and creates a dummy account which is deleted at the end of the call
• do the service discovery to check the server supports whatever is needed (e.g. MUC, Jingle etc.) (XEP-0030)
• try to connect to server over SCION first (if rains resolution returns true), otherwise use IP - you could also indicate to the user which one was used to connect
  • I will also need this to be able to make c2s over scion
• it would be good to have both (call someone/create a group call)
• MUC I can design and implement without having the client support

Specifications

• Specifications that client application should implement:
  • Already implemented:
    • XMPP Core
    • XMPP IM
    • XEP-0012: Last Activity
    • XEP-0030: Service Discovery
    • XEP-0054: vcard-temp
    • XEP-0077: In-Band Registration
    • XEP-0199: XMPP Ping
  • Implementing:
    • XEP-045 MUC (enough to have a demo)
    • XEP-0166 Jingle (one to one call)
    • XEP-0272 Multiparty Jingle (conference call)

Connect to the deployed server

• 129.132.121.173 netsec-xmpp.inf.ethz.ch
• currently only accessible over IP to the clients (for scion we might need client first)
• find a way to share server log file with Mike (this should help with the development)
  • log and config file accessible at port 6060 over http (hostname:6060/log/ and hostname:6060/config/)
• use profanity (console, good for everything but in-band registration) or Psi (GUI client)
