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.

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, a first plurality of messages including messages indicative of a rate of arrival at the second node of the messages transmitted from the first node and 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 first plurality of messages. Transmission of messages from the first node to the second node is limited according to the maintained first transmission limit, and according to the second transmission limit.

Abstract: Systems and methods of redundancy for real time communications are disclosed. One such system includes a first device and a second device, where the first device includes a redundant tunneled services element (RTSE) and the second device includes a redundant tunnel services control function (RTSCF). The RTSCF is in communication with the RTSE and is operable to establish a redundant secure tunnel to the RTSE. The RTSE is operable to redundantly convey a first stream of media packets over the redundant secure tunnel to the RTSCF. The RTSCF is operable to redundantly convey a second stream of media packets over the redundant secure tunnel to the RTSE.

Abstract: Control and management of bandwidth at networks remote from the physical bandwidth management infrastructure. Particular implementations allow network equipment at a plurality of data centers, for example, to manage network traffic at remote branch office networks without deployment of network devices at the remote branch office networks.

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.

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.

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.
