13.3 MDI analysis
The ARGUS actively - or in bridge or router mode passively - analyzes a UDP/RTP data
stream (UDP: User Datagram Protocol, RTP: Real-Time Transport Protocol) and
determines the MDI (Media Delivery Index) in accordance with RFC 4445: Display of the
Media Loss Rate and Delay Factor.
The following parameters, which are stored in a profile, are required to perform a MDI
analysis (if a xDSL or Ethernet connection has already been setup, the connection
parameters, e.g. the ADSL mode and the rated value, are blocked):
