During route computation, APPN determines the optimum route through a network in the following steps: - obtains the required route characteristics from the COS database using the mode name specified in the session request - determines all possible combinations of transmission groups and nodes that form a route to the destination database - the actual characteristics of the Nodes and TGs in these routes are compared against the COS tables that contain the required characteristics of the session. A weight is assigned based on how well the actual characteristics meet the required characteristics. Where there is no match between actual and required characteristics, the route containing the node or TG is excluded from further computation. - Each possible route is quantified by adding the weights assigned to the node and TGs in the route. The route with the lowest weight is the one used for the session. This attribute is part of the COS tables and contains the maximum acceptable value for user defined routing parameter number 3.
