  Hi,

   

  according to my last post I have couple of questions regarding QoE reports.

   

  1) Degradation values (Degradation, Degradation Jitter and Degradation Packet Loss)

   

  How are the figures caculated based on this following example:

   

  Network MOS 3,14

  Degradation 0,96

  Degradation Jitter 0,33

  Degradation Packet Loss 0,66             

   

  2) Packet lost

   

  Several different sources explain that a healthy network are design for 0,5% avarage lost of the packages.

   

  Compared to OCS 2007 Voice/Vidoe what is maximal suitable for this scenario? 10% lost or xx?

   

  2) Jitter

   

  The same question as for Packet lost, what is the maximal suitable figure for jitter? 

   

  3) Burst

   

  The same question as for Packet lost, what is maximal suitable figure for Burst? 

   

  I have researched in several different WhitePapers and find out an example as banchmark and need asistend to compare it to real figures for my scenario.

   

  Main Scenarios	Packet loss	Burstiness	Jitter
  "Perfect NSQ” network	Zero	Zero	Zero
  Typical enterprise network	Low	Low	Medium
  Overloaded enterprise network	Medium	High	Medium/High
  Multisite connectivity	Medium	High	High
  Internet conditions	High	Medium	High

   

  Thanks
