A method for computing cost information associated with a port of a switch in a network of switches. Cost information is computed as a port load factor: a ratio of port latency over available throughput. Port latency is determined as the depth of a queue associated with the port divided by the speed of the port. Available throughput is determined as the speed of the slowest port on a given path associated with the port in question. Preferably, the queue depth is measured in bits and the port speed and available throughput are measured in bits per second. Further, in the preferred embodiment, port latency is computed as a weighted average as ((15xprevious latency)+current latency)/16. A higher value for the port load factor indicates a port which is more heavily loaded. The load factor is therefore useful in load balancing among the ports of switches and paths associated therewith.

A computer-implemented method for performing dynamic cost accounting for an enterprise, wherein the enterprise includes a costing system. The method includes programmatically retrieving input information for the costing system, e.g., from one or more (possibly remote) information sources over a network, dynamically updating the costing system in accordance with the retrieved input information to generate an updated costing system, and the updated costing system calculating one or more outputs which are usable in managing the enterprise. The retrieving and update may occur periodically, e.g., monthly, weekly, per hour, minute, second, millisecond, etc., or on demand. In some embodiments, the enterprise may further include one or more optimizers, wherein the optimizers are provided with the one or more outputs of the costing system, and executed to determine one or more optimal operating parameters for the enterprise. The determined optimal operating parameters are then used to manage or execute enterprise operations.

The present invention relates generally to arranging for free or discounted transportation to an advertiser's business location. More specifically, the invention involves automatically comparing the cost of transportation and the potential profit from a completed transaction using a number of real-time calculations. For example, the calculation may consider various factors including a consumer's current location, the consumer's most likely route and form of transportation (such as train, personal car, taxi, rental car, or shared vehicle), the consumer's daily agenda, the price competing advertisers are willing to pay for the customer to be delivered to alternate locations, and other costs. In this regard, the customer's obstacles to entering a business location are reduced while routing and cost calculations are automatically handled based on the demand for the advertiser's goods and potential profit margins.

A route from a source node to a destination is discovered in an ad hoc network by having the source node generate a data packet including its source address, the destination address, and a field indicating that the source node requests route information from the source node to the destination node. The data packet is forwarded through the network until the data packet is received by the destination node. In response, the destination node generates a route reply packet including the route information. The route information can include a cost. The route reply packet is forwarded through the network until the route reply packet is received by the source node. During the forwarding, multiple route reply packets can be generated with different costs. The source node can then make cost calculations to select a best route based on the costs.
