Un-Addressed Areas in e-VLBI system

• EGAE
• Scientist to enter experiment description
• In own vocabulary
• Utilize Scripts and done manually
• Experiment Profile creation / distribution
• Network configuration / monitoring
• Scheduling
• VTP
• Execution of application
• Centralized control of system
• Network resources as related to e-VLBI

e-VLBI Access Point (eAXP)
5
e-VLBI Access Point (eAXP)

• Web based application (browser accessible)
• Creates eXtensible Markup Language (XML) Profile
  of an experiment
• General information about experiment
• session name, start date, time, duration, etc.
• Correlator Specific information
• id, correlation type, deadline
• Network requirements as derived from EGAE
• Bandwidth, Packet loss
• Station Specific Information
• id, source, destination, scan information, mode
• Network management / configuration
