  • Patent number: 9384161
    Abstract: Methods and apparatus for facilitating data throughput improvements in interconnect fabrics employing point-to-point links using dynamically selectable routing. Initiators and targets are operatively coupled to first and second fabrics. The first and second fabrics include multiple point-to-point internal links and are communicatively coupled to one another via multiple fabric-to-fabric links, including first and second links from the first fabric to the second fabric. During operations, traffic on the first fabric-to-fabric link is detected to determine if it is busy, and depending on the determination, data transfers from an initiator coupled to the first fabric destined for a target coupled to the second fabric are selectively routed via either the first or second fabric-to-fabric links.

  • Patent number: 8625582
    Abstract: A communication system is provided that routes a bearer path of a communication session between an originating Node B and a terminating Node B via an X2 interface, bypassing an IMS core network, while continuing to route the signaling path to an IMS network, thereby allowing the IMS network to retain control of the bearer path while avoiding delay, potential for data loss and jitter to the bearer stream, and additional backhaul capacity requirements that result from routing the bearer path between the originating and terminating Node Bs via the IMS core network. In determining whether the bearer path may bypass the IMS core network, the communication system determines whether IMS core network bearer associated services are required for the communication session such that a bearer path of the call will need to be routed to the IMS core network in order to provide such services.

  • Patent number: 8160234
    Abstract: A technique is disclosed that optimizes the background noise experienced by a party who is calling into a call center. Working as part of an overall call-assignment algorithm, the technique considers the acoustic noise that is present in the vicinities of multiple call-center agents who are otherwise satisfactory candidates to handle a call. The technique then selects an agent to handle the call who is associated with an optimal acoustic noise. Typically, the selected agent is associated with lowest background noise level. The background noise is monitored at each call agent's station by evaluating the signals that are present at the agent's microphone. Usually, this is done when a call agent is between calls and, as a result, is not using her headset at that moment. In other words, the background noise is actually measured, and the measurements are then used to assign a call agent to the incoming call.

    Abstract: A method and system is provided wherein routing information is obtained from previously cached information or from a gatekeeper. An originating gateway in a network receives a request for a connection and determines whether pertinent routing information is cached. If available, the cached routing is used to attempt to establish a connection. If no previously established routing is available, the originating gateway requests preferred routing from a gatekeeper, including prioritized selections of terminating gateways through which to make a connection to a designated call recipient.

  • Patent number: 6975717
    Abstract: A system and method are disclosed for selective processing of calls using alternative network telephony. Called party data is received indicating a destination to which a calling party using a local telephone equipment desires to place a call. It is determined transparently to the calling party whether the called party data satisfies a first criteria for completing calls via alternative network telephony. The call is completed using alternative network telephony if it is determined that the called party data satisfies the first criteria. The call is completed via the public switched telephone network (PSTN) if it is determined that the called party data does not satisfy the first criteria.

  • Patent number: 6956858
    Abstract: A routing table circuit for a router has one or more input ports and output ports for message communication. In the routing table circuit, one or more routing table memories store a plurality of routing table arrays. The routing table arrays are arranged hierarchically in levels, and each routing table array is associated with a predetermined subset of prefixes. Each routing table array has entries. The entries include a block default route pointer field to store a block default route pointer, if any, and a routing field. The route engine may access any level of table array by using a next level route pointer stored in the routing field. Using the block default route and the routing field, the present invention further reduces the number of memory accesses and the update cost for route insertion and deletion by identifying and skipping elements that do not require route updating.

  • Patent number: 6816585
    Abstract: A method for routing of incoming prioritized telecommunication traffic in a telecommunication network by applying an algorithm of finding optimal path to an augmented graph built for said telecommunication network. The telecommunication network is represented as a network graph comprising nodes (A, B, C, D, E) and real links (AB, BC, CD, ED, AE) bridging the nodes, while the augmented graph is a graph built on the basis of the network graph by adding to it virtual links (ABC1, . . . , EDC3). The augmented graph comprises nodes and edges, wherein the edges of the augmented graph are weighed to reflect priority of the telecommunication traffic presently taking place there-through. For placing a new call according to the method, a pathfinder optimization algorithm is applied to the augmented graph to determine an optimal pathfinder solution, having the minimal total weight, for routing the new call in the augmented graph.
