Description: The mode the path selection function must use to select a path for this VC. Best available service uses the lowest cost path(s) which meet the cost requirement as the primary path. With this approach, the first calls set up in the network potentially receive a higher quality service than calls which happen to arrive later. Best fit service uses the highest cost path(s) which meet the cost requirement as the primary path(s). This approach uses the least required resources to satisfy the cost function and conserves the higher quality of service for those calls which may require them. Common Name: Path Selection Mode
