4.3 Setting Action Values

The above considerations are based on the assumption that usual values really exist, i.e. that a certain regularity is detectable in the network traffic.

Action values are thus based on the following:

1. Collect information about the traffic in the network and map it to usual values, i.e. define the granularity for this mapping.

2. Relate the usual values with the needed action values.

The following usual values must be estimated:

• 
  -- Average number of usually active connections on this link.
• 
  -- Average number of usually configured connections on this link.
• 
  -- Average amount of mean bandwidth usually requested by connections on this link.
• 
  -- Average number of cells transported with one connection on this link.
• 
  -- Average duration of a connection on this link.

We need to select action values for the following set of parameters:

• 
  -- Indication of congestion
• 
  -- Indication of call blocking
• 
  -- The maximum allowed difference between used resources and allocated resources and the time this difference is tolerated.
• 
  -- The maximum amount of discarded cells on a connection before the user recognizes problems.

Due to the considerations in section 4.2 the relationships are set as follows.

• 4.3.1 Call blocking indication
• 4.3.2 Not-accurate-bandwidth indications
• 4.3.3 Congestion indication
