CSD Load Balancing Algorithms – Windows NT Parameters

This window manages the configurations for the two additionial load balancing algorithms available with Windows NT servers. These parameters are used to load balance the users of the farms that are configured with nt-1 or nt-2 dispatch methods.

The Windows NT Parameters Table window displays the following:

• Serial No. – The serial number of the scheme. Scheme number 1 is used for dispatch method nt-1, etc.

• Check Period – The time interval between queries for the frequently updating parameters (number of open sessions, amount of traffic).

• Open Sessions Weight – The relational weight for considering the number of active sessions on the server.

• Incoming Traffic Weight – The relational weight for considering the amount of traffic coming into the server.

• Outgoing Traffic Weight – The relational weight for considering the amount of traffic going out of the server.

• Regular Check Period – The time interval between queries for other less dynamic parameters (average response time, limits on users and TCP connections).

• Response Weight – The relational weight for considering the average response time of the server.

• Users Limit Weight – The relational weight for considering the limit on the number of logged in users on the server.

• TCP Limit Weight – The relational weight for considering the limit of TCP connections to the server.

• Retries – Defines how many unanswered requests for a variable will make it be ignored in the load balancing decision.

• NT Community – The community name to use when addressing the server.
