ABSTRACT:
A system allocates data links between a switch and a database for data transactions in a telecommunications network. The data links between the switch and the database carry the transaction data for providing routing, card verification, address translation information, etc. by the database. The Flexible Link Selection Algorithm provides for accessing the data links using the round-robin method, wherein each data link is accessed sequentially to transport the data to and from the database. Alternatively, the Flexible Link Selection Algorithm provides for accessing the data links using dynamic allocation based on the least cost routing between the switch and the database. In the latter mode, the switch uses the least "expensive" database, i.e., database having the least cost routing between the switch and the database, until the volume of data transactions in the data links associated with that database exceeds a predetermined threshold level. If the threshold level is exceeded, the next least "expensive" database is selected, and its data links are utilized used to carry the data transactions between the database and the switch.
