  • Patent number: 8953486
    Abstract: A method involves receiving information identifying one or more virtual connections (VCs) available within a network and one or more IP subnets. The information is received by the first of several nodes coupled by the network and identifies either (or both) a first VC that is not locally available at the first node and a first IP subnet that is not configured on the first node. Information identifying a global topology of the network is generated, based upon the received information. The global topology includes each of several active VCs within the network and each of several IP subnets configured on the nodes coupled by the network. One of the IP subnets is then assigned to the one of the VCs, based upon the global topology of the network, until all of the IP subnets are assigned, each to a unique VC.

  • Patent number: 8667095
    Abstract: Various systems and methods for automatically configuring network devices coupled to a network that provides (or is capable of providing) multipoint virtual connections are disclosed. One such method involves receiving information identifying a plurality of virtual connections (VCs) available within a network. The method identifies a set of one or more nodes that are configured with one of several Internet Protocol (IP) subnets and that have access to one of the VCs, and then assigns each of the IP subnets to a unique one of the VCs.

  • Patent number: 7302054
    Abstract: A telephony system includes a switch coupled to a call agent and a legacy application, and further coupled to resources, some controlled by the call agent and others controlled by the legacy application. The switch processes connection requests from the call agent and the legacy application, and, using a resource emulator as an intermediary, establishes connections between call agent controlled resources and legacy application controlled resources.

  • Patent number: 6807150
    Abstract: A telephony system includes a hybrid switch coupled to a packet network and a TDM network. The switch establishes a communication session using one of these networks and then switches the communication session to the other one of these networks in response to stored metrics, user request, or other criteria.
