A method and system for determining the best data path in a communication network is presented. A Least Cost Routing path between end users in a multi-network environment, including both public and private networks, is determined based upon a longest prefix match. At network activation time, the numbers or prefixes of numbers of end users attached to the public network (304, 305) are stored in entry node data bases A and C of the private network (303). Assuming an end user terminal U1 calls a target end user U3, an entry node B first checks for a longest prefix match between the called number and numbers already stored into its memory. If this is the first time U3 is called via node B, no match will occur and node B will then broadcast a Query to all nodes in the private network (i.e. Nodes A and C). Only those nodes providing possible access to U3 answer this Query. Node B then determines the longest prefix match with the called number amongst the various query answers, and sets the data path via that node having the longest prefix match.

Compliance with subscriber job delivery requirements is managed and tracked. Job requirements set forth in service level agreements are stored electronically as delivery parameters. A queue manager creates a prioritized list of delivery jobs. A delivery manager delivers the jobs in accordance with the prioritized list. A routing manager determines optimal routes, e.g., least cost route for delivery of each job. Retries of jobs that are not successfully delivered can be performed. delivery job sources include broadcast subscribers, high- and low-priority single address subscribers, free subscribers and off-peak subscribers.

A method and system for directing data packets from an origin node to a destination node in a multipath communication network having a plurality of nodes, where each node is connected to at least one other node by links. The apparatus includes a processor for obtaining cost information relating to each link in the network and for determining the least-cost route between the origin node and the destination node based on the cost information relating to each link. The processor establishes a cost margin representing a range of costs above the cost of the least cost route and identifies one or more alternate routes. A data storage device stores the cost information, and a network interface selectively routes the data packets through one or more of the least cost route and the one or more alternate routes falling within the established cost margin thus balancing the network load and providing alternate data paths in case the least-cost path is unavailable.

A pro-active message delivery system which routes digitally-encoded messages via public-switched telephone networks and wide area networks to most cost-effectively deliver the messages, subject to security, privacy, and availability considerations. In a preferred embodiment of the invention, digitally encoded messages entered into a wide area network, either directly or via a public-switched telephone network, are sent to their destination using the most cost-effective route, by calculating the cost of sending the message via the available routes, and selecting the lowest cost route. Generally, the lowest cost route might use the node on the wide area network closest to the recipient of the message, or might use or node located in an area which charges off-peak rates at the time of transmission.

Systems and methods are disclosed for routing a transaction based on an assessment of costs associated with multiple payment processing networks. A transaction broker server determines how to route a received authorization request message for a transaction based on a first cost associated with processing the transaction via a first payment processing network and a second cost associated with processing the transaction via a second payment processing network. If the first cost is less than or equal to the second cost, the authorization request message is routed to the first payment processing network. If the first cost exceeds the second cost, at least one rule is applied to determine whether the first cost is to be reduced. If the at least one rule is satisfied, the first cost is reduced and the authorization request message is routed to the first payment processing network.

A method is disclosed of forwarding data in a data communications network comprising a plurality of nodes and links therebetween, each link having an associated usage cost and a load capacity. A forwarding node identifies a lowest cost route, comprising one or more links, to a destination node. If a plurality of lowest cost routes is identified, then the forwarding node allocates data for forwarding along each of the lowest cost routes dependent on a relative load capacity of that route.

A system and method are described for providing least-cost call routing for mobile wireless devices having access to voice-over-IP (VoIP) infrastructure, such as may be operated by an enterprise having global presence. Using a local wireless connection, such as a wireless local area network (WLAN), a software agent on the mobile wireless device registers with a common, enterprise-wide registrar, which, in turn, informs a VoIP gateway in the device's home region of the device's new location. The home region VoIP gateway will then re-route incoming calls for the device to a VoIP gateway serving the region in which the device is currently located. The local VoIP gateway will then route the call to the device via the WLAN. Seamless routing occurs even when the wireless device obtains a local phone number in a foreign network. Outgoing calls from the device can be routed via the VoIP infrastructure or the foreign network based on availability of service and / or cost.

A method and system for communications routing provides an improved range of service quality and cost options. The method includes receiving at a host computer system an indication that a user has placed a telephone call. Next the host computer system receives from a routing database operatively connected to the host computer system both QoS criteria and cost criteria. The QoS criteria and cost criteria are then matched with empirical QoS data and least-cost routing data, respectively. A call route is then determined based on the matched QoS criteria and cost criteria with empirical QoS data and least-cost routing data, respectively. The routing database is then updated based on whether the determined call route provided an acceptable QoS.

Additionally, the invention allows the service provider to block the dialer type traffic, in which case the algorithm returns a “release-back” code.

A private network associated with an enterprise interconnects multiple points of presence (POPs) located in regions in which communications devices associated with the enterprise operate. In addition, the communications devices and POPs are each connected to the public switched telephone network (PSTN) and / or the Internet, or collectively, public network. Upon origination of a call from a device, a call management agent (CMA) on the device determines, based at least in part on the intended destination of the call, whether to allow the call to proceed conventionally over the public network, or whether to direct the call to a first POP for conveyance over the private network to a second POP, and from the second POP to the called device. The determination made by the CMA as to how to direct the outgoing call is based on minimizing the cost thereof. A call management server may be provided from which the CMA can obtain current cost and network information for use in making the aforementioned determination.
