Nicest to have

• Access Node has
• Local Information
• Global Coordination ?

Application info Connectivity info
Metric taking into account retransmissions
Info on input signal (reduced reference metrics ?)
Delay, Loss info

To Do

• Given Architecture
• Define Implementation (functional architecture,
  protocols, )
• Build analysis for this case
• Access Network
• DSL Connection
• Intermediate monitoring functions
• Find analysis algorithms
• Check what we can detect
• required granularity of monitoring
• Tools
• Simulation ?
• Other ?
