  • Patent number: 8406221
    Abstract: There is provided herein a system and method for automatic configuration of data routings for use with electronic data such as phone calls, faxes, etc. In the preferred embodiment, when more than one carrier might potentially terminate the transmission, the carriers are ordered based on some screening criterion (e.g., transmission price). Data transmissions are then assigned to the carriers based on the sorting order, with the second place and lower carriers (e.g., the higher priced carriers) not being selected unless the first carrier cannot complete the transaction. The switch instructions necessary to implement this scheme are generated automatically.

  • Patent number: 8406398
    Abstract: An embodiment of a method includes selecting call detail report (CDR) call setup attributes from captured CDR data, refining the CDR data, and summing CDR amount attribute values for each set of CDR call entries having common values for the selected CDR call setup attributes. Each set of one or more CDR call entries having common values for the CDR call setup attributes are combined into a single refined CDR call entry having the common CDR call setup attribute values and the summed CDR amount attribute values. The summing process is repeated for each set of CDR data associated with each of a plurality of network elements. After summing the CDR attribute amount values for call entries having common CDR setup call attribute values for each switch, CDR attribute amount values associated with common CDR setup attribute values in call entries associated with all switches are summed to generate a final set of refined CDR data.

  • Patent number: 8401161
    Abstract: A method for routing a toll-free call through a network includes receiving a toll-free call from a call origination endpoint, determining an identifier associated with the call origination endpoint, determining a meet point trunk based on at least a portion of the identifier if a DAL is not available, and routing the toll-free call to a LEC via the determined meet point trunk. A system for routing a toll-free call entering a network to an appropriate carrier includes an inbound gateway device configured to receive a toll-free call from a call origination endpoint having an assigned telephone number and to query a core routing engine (CRE) for a route plan using the assigned telephone number, and a CRE configured to select an interconnection access line based on the origination endpoint telephone number, wherein the interconnection access line is connected to a LEC that is operable to route the call to the appropriate carrier.

  • Patent number: 8301774
    Abstract: A method for delivering resources to clients in a distributed computing environment. At least a first resource associated with a first content provider and maintained on an origin server references a second resource. The second resource is associated with a network formed by a plurality of repeater servers operable to serve the second resource to clients on behalf of the first content provider, the origin server being distinct from the plurality of repeater servers. Responsive to a request that causes the first resource to be served to a client from the origin server, at least one of the plurality of repeater servers is selected to serve the second resource to the client. If a copy of the second resource is available on the selected repeater server, the copy of the second resource is served to the client from the selected repeater server; otherwise, if a copy of the second resource is not available on the selected repeater server, the second resource is replicated on the selected repeater server.

  • Patent number: 8285141
    Abstract: An asymmetrical and dynamic routing system (ADRS) is provided to enable the dynamic adjustment of the bandwidth capacity of two or more network devices exchanging data. The two or more network devices monitor their current bandwidth demand between themselves and others in a network and a first network device can transmit bandwidth request to a second network device when the first network device reaches transmission bandwidth capacity. Each network device is further configured with additional transmit and receive ports and can be selectively enabled in response to a bandwidth request from other network devices. Each network device is further configured to generate control signals that are sent to optical mirrors to re-direct data signals to or from the one or more enabled additional transmit and receive ports.
