Conference Controller

Implement a Java-based Internet multimedia conference controller client.

Project goals

• Based on Java JDK-1.1. Client possibly a signed applet (since it needs to accept network connections from sources other than the web server and needs to start applications).
• The controller should be able to parse and generate SDP messages, similar in functionality to the sdr session directory tool.
• Possibly use the Netscape calendar /usr/local/pub/bin/nscal to schedule repeat transmissions and view entries. In any event, use vCalender format for scheduling.
• It should be able to operate within the pmm local control framework, generating and receiving multicast status messages. The controller sends a message, waits for a response and times out if no application responds. If no response, it uses the mailcap entries to start a new application.
• Members of a group of multicast sessions are displayed by name and possibly photo in a tabular format. Each member has an indication which media he/she is using. Left-clicking on the media indication enables and disables receiving that media from that source; right-clicking shows statistics.
• Members can invite others to the session using the Session Initiation Protocol (SIP).
• Graphical display of per-user statistics.

Requirements

• Knowledge of Java
• Unix system knowledge (e.g., CS W4118).
• Familiarity with network protocols and issues (AIS, CS W4119).
