摘要： Techniques are disclosed for generation of spanning trees that support provision of performance-guaranteed services over a circuit-switched network such as, for example, an optical-based network. For example, a technique for generating a spanning tree for use in forwarding Ethernet-based data in a circuit-switched network comprises the following steps/operations. Input information is obtained. The input information comprises a representation of the network, a set of Ethernet-enabled nodes in the network, and a set of demands. A spanning tree is computed based on at least a portion of the input information such that the spanning tree substantially satisfies one or more performance requirements (e.g., one or more bandwidth requirements) associated with the set of demands. Advantageously, in one embodiment, such techniques may provide for generation of spanning trees for use in supporting bandwidth-guaranteed Ethernet services such as E-LAN over a SONET (and SDH) network.

摘要： A system for and method of multi-protocol label switching (MPLS) network tuning. In one embodiment, the system includes a hot zone clearing subsystem that recursively identifies label switched paths (LSPs) to be rerouted from a defined hot zone subject to edges to be avoided. In that embodiment, the system further includes an LSP ordering subsystem, which is coupled to the hot zone clearing subsystem, that orders the LSPs to be rerouted to yield a migration sequence. The migration sequence is employable to reduce a load of the hot zone.

摘要： A maximum-flow based route precomputation algorithm includes at least a route generation phase and a route selection phase, and determines one or more routes between at least a given pair of nodes in a network. In the route generation phase, a maximum-flow algorithm is applied to a first set of information characterizing links between the given pair of nodes in the network. The output of the maximum-flow algorithm is utilizable to generate a second set of information characterizing corresponding admissible flows. In the route selection phase, one or more routes are determined based on the second set of information using, for example, a shortest widest path (SWP) algorithm. The route generation and route selection phases may be repeated for each of a plurality of node pairs of the network.

摘要： Advertisements or other types of targeted information are delivered to set-top boxes or other user interface devices of a signal distribution system. In one aspect of the invention, a user interface device comprises at least first and second software clients and a video buffer. The first software client receives packets associated with a first media stream, and the second software client receives packets associated with a second media stream containing the targeted information. The first software client delivers at least a portion of the packets associated with the first media stream to the video buffer. The second software client delivers at least a portion of the packets associated with the second media stream to the video buffer while one or more packets of the first media stream are still in the video buffer. The user interface device switches from the first media stream to the second media stream based on timing information which may be received from an external detection server.

摘要： Advertisements or other types of targeted information are delivered to a set-top box or other user interface device of signal distribution system. In one aspect of the invention, a detection server of the system detects at least one cue associated with a first media stream, and generates timing information from the detected cue. The timing information is signaled to the interface device. An advertisement server of the system generates a second media stream containing targeted information for delivery to the user interface device. The user interface device switches from the first stream to the second stream based on the timing information. The timing information may also be signaled by the detection server to the advertisement server, for use in controlling generation of the second stream.

摘要： A method for generating an approximate answer to a query in a database environment in which the database has a plurality of base relations. A query relating to a database is received, and an approximate answer to the query is generated such that the approximate answer is based on at least one join synopsis formed from the database. The method further includes steps of forming a sample-tuple set for at least one selected base relation of a plurality of base relations of a database such that each sample-tuple set contains at least one sample tuple from a corresponding base relation, and forming a join synopsis set for each selected base relation such that each join synopsis set contains a join synopsis for each sample tuple in a sample-tuple set. A join synopsis of a sample tuple is based on a join of the sample tuple and at least one descendent relation of the sample tuple. All join synopsis sets form a statistical summary of the database and are stored.
