  • Publication number: 20190036650
    Abstract: A method for data communication between a first node and a second node over a data path includes determining one or more redundancy messages from data messages at the first node using an error correcting code and transmitting messages from the first node to the second node. The transmitted messages include the data messages and the redundancy messages. The method includes, receiving, at the first node, messages indicative of a rate of arrival at the second node of the messages transmitted from the first node, and receiving messages indicative of successful and unsuccessful delivery of the messages transmitted from the first node to the second node. A first transmission limit and a second transmission limit are maintained according to the received messages. Transmission of messages from the first node to the second node is inhibited according to the maintained first transmission limit, and according to the second transmission limit.

  • Publication number: 20180331967
    Abstract: A method for data communication between a first node and a second node over a data path coupling the first node and the second node includes transmitting a segment of data from the first node to the second node over the data path as a number of messages, the number of messages being transmitted according to a transmission order. A degree of redundancy associated with each message of the number of messages is determined based on a position of said message in the transmission order.

  • Patent number: 10129159
    Abstract: A method for data communication between a first node and a second node over a number of data paths coupling the first node and the second node includes transmitting messages between the first node and the second node over the number of data paths including transmitting a first subset of the messages over a first data path of the number of data paths, and transmitting a second subset of the messages over a second data path of the number of data paths. The first data path has a first latency and the second data path has a second latency substantially larger than the first latency, and messages of the first subset of the messages are chosen to have first message characteristics and messages of the second subset are chosen to have second message characteristics, different from the first message characteristics.

  • Patent number: 9379914
    Abstract: A method and system are adapted to provide telephony services to aggregate endpoints on an Internet Protocol Multimedia Subsystem (IMS) network. The method includes assigning one or multiple PUIDs for surrogate registration purposes during the provisioning of the aggregate endpoint, performing reliable surrogate registration on behalf of the aggregate endpoint, allowing multiple SBCs to perform surrogate registrations independently for the same aggregate endpoint to achieve reliability, and providing reliable connection from an IMS core to the aggregate endpoints via multiple S/BCs. The system includes one or more Session Border Controllers (S/BC), at least one set of Call/Session Control Functions (CSCF), and an HSS operatively coupled together.

  • Patent number: 9112781
    Abstract: Network operating methods provide a first packet switch coupled to a second packet switch via a primary packet tunnel having an active status and one or more inactive backup packet tunnels having an inactive status. The methods access data describing at least one performance characteristic of the primary packet tunnel and, based at least on the data, deactivate the primary packet tunnel while still operational and activate one of the backup packet tunnels. Network operating methods provide a first device coupled to a second device via an active primary packet tunnel and one or more inactive backup packet tunnels, access data describing performance characteristics of the one or more backup packet tunnels, and, based at least on the data, deactivate the primary packet tunnel and activate one of the backup packet tunnels.

  • Patent number: 8767715
    Abstract: Systems and methods of establishing IP telephony sessions between enterprises are disclosed. A first enterprise requests an association with a second enterprise. Both enterprises and the second enterprise belong to the same federation. The association request is accepted, to establish an association between the first and second enterprises. In response to the acceptance, a direct routed path is established between the first enterprise and the second enterprise. One of the associated enterprises requests activation of an IP telephony service. If the request to activate references the association, an IP telephony session is established using the direct routed path.

  • Patent number: 8625456
    Abstract: This document describes tools that withhold a data packet from a switch port despite its destination address. In one embodiment, the tools may receive a port description identifying a set of switch ports. The tools configure the set of ports so that data packets exchanged through the switch by interested entities that would otherwise be forwarded to uninterested entities are instead withheld from the uninterested entities. In another embodiment, the tools may configure a data-packet switch according to a port description identifying a set of ports and a subset of the set of ports. The tools receive a data packet that includes a broadcast destination address on a receive port and then determine, based on the port description, whether the receive port belongs to the subset. If the receive port does not belong to the subset the data packet is withheld from the other ports of the set.

  • Patent number: 8576840
    Abstract: This document describes tools that assign packets to a network service. The tools receive a control packet lacking a tag associating the control packet with a network service and assign the control packet to a network service by adding a tag to the control packet. The tools may also receive a tagged data packet on a port and determine that the tag does not match any of a set of network tags associated with the port. Consequently, the tools assign the data packet to a default network service. The tools may also receive a set of conditions for a port and assign data packets received on the port that satisfy one of the conditions to a network service associated with the satisfied condition and data packets that do not satisfy one of the conditions to a default network service.
