Abstract: A particular method includes measuring port usage data related to each of a plurality of physical ports associated with a link aggregation group. A bandwidth requirement of a requested media stream is estimated and added to a traffic load at each of the plurality of physical ports to produce an estimated total traffic load of each of the plurality of physical ports. When the requested media stream includes non-video data, the requested media stream is sent to a destination device via a physical port that selected in accordance with a static bandwidth allocation. When the requested media stream includes video data, the requested media stream is sent to the destination device via a least loaded physical port that is dynamically identified based on the estimated traffic loads of each of the plurality of physical ports.

Abstract: A method to perform dynamic source selection within an IP multicast network is performed at a designated router of an IP multicast network. At the designated router within the IP multicast network, a first source of a multicast group is selected to be forwarded to a receiving host or multiple receiving hosts. The first source is monitored to automatically detect when the first source exhibits a predetermined characteristic. At the designated router, responsive to the detection that the first source exhibits the predetermined characteristic, a second source of the multicast group is automatically selected to be forwarded to the receiving host or hosts. The method also supports automatic selection of all normally operating sources and forwarding of the traffic of such sources or channels to the receiving hosts or hosts.

Abstract: A method of delivering video content includes receiving a request for a video stream at a network device of a video distribution network. The request is received via a network link associated with a link aggregation group. The method includes determining a current real-time traffic load at each of a plurality of physical interfaces associated with the link aggregation group at the network device. Further, the method includes identifying an interface having a lowest traffic load of the plurality of physical interfaces. The lowest traffic load is lower than a pre-defined threshold. The method includes determining a total traffic load for the identified interface. The total traffic load includes an estimated traffic load corresponding to the requested video stream and including the lowest traffic load. The method also includes sending the requested video stream via the identified interface when the total traffic load is lower than the pre-defined threshold.

Abstract: Communication between a source and a destination is dynamically established. A connection request is received. The connection request is based on a request transmitted over a best-effort path from the source. A network connection is established having a specified quality of service (QoS) based on the request between the source and the destination. Data for a first application is transmitted over the network connection and data for a second application is transmitted over the best-effort path.

Abstract: Policy-based routing of packets over a peer-to-peer, quality of service connection includes sending a connection setup request, over a control connection to a connection establishing device, to dynamically establish the peer-to-peer, quality of service connection between a source peer implemented on at least one device and a destination peer implemented on at least one device. Packets originating from an application requiring a specified level of service are transmitted, from the source peer implemented on at least one device, over the peer-to-peer, quality of service connection. Packets originating from an application that does not require the specified level of service are transmitted, from the source peer implemented on at least one device, over a best effort connection.

Abstract: A subscriber dynamically establishes a peer-to-peer session from a source subscriber to a destination subscriber across a switched virtual circuit (SVC). A signaling (control) connection is established from the source subscriber to a server, and a connection request is sent via the signaling (control) connection to the server requesting establishment of the SVC to the destination subscriber. In response, a database is queried for information about a source switch associated with the source subscriber and a destination switch associated with the destination subscriber. Subsequently, the connection request is forwarded to a proxy signaling agent, and the proxy signaling agent signals the source switch and the destination switch to dynamically establish the SVC connection from the source switch to the destination switch. This abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way.

Abstract: The disclosed method and system provides a new service provision interface that allows operator use without requiring many of the specific technical network details, such as VRF, RT, SOO, route redistribution, etc. Further, the translation from a customer's requirements (including both VPN topology membership requirement and L2, L3 requirement from customer) into technical network configuration commands are handled using an automated method that is transparent to the operator. In a particular illustrative embodiment of this patent disclosure, a high level table with reduced technical detail is generated by an operator and an automated provisioning system, without operator visibility or required operator interaction, creates intermediate data including network specific technical information in an automated process to generate a deployable network topology including VRF and RT assignments for use in network provisioning.
