摘要： Link delay is determined in a network comprising a plurality of nodes by identifying pairs of nodes associated with a given link, and, for each of the identified pairs, setting up a virtually-concatenated group (VCG) between the nodes of that pair. The VCGs are utilized to make delay measurements, and the delay measurements are processed to determine delay of the given link. In an illustrative embodiment, the VCGs comprise two-member VCGs with the members being routed on opposite sides of a logical ring. For a given one of these two-member VCGs, a differential delay measurement is made at a particular one of the associated nodes by comparing frame indicator fields for concurrently arriving frames. A system of equations is generated based on the differential delay measurements made utilizing the VCGs, and the system of equations is solved to obtain information utilizable to determine delay of the given link.

摘要： A subscriber or other user is provided with access to a subscription service of a signal distribution system at a roaming location remote from a home location of the user. The subscription service comprises a plurality of selectable channels available to the user at the home location. In one aspect of the invention, a request for initiation of a roaming session is received, and responsive to initiation of the roaming session, at least one user interface is generated for presentation on a device at the remote location. The generated user interface is configured to provide access at the remote location to one or more of the channels available to the user at the home location, and represents an at least partial alteration of a normal user interface that would otherwise be presented on the device at the remote location in the absence of the roaming session.

摘要： A subscriber or other user is provided with access to a subscription service of a signal distribution system at a location remote from a home location of the user. The subscription service comprises a plurality of selectable channels available to the user at the home location. The user is assigned one of a plurality of program streams utilizable for delivery of content from the head end equipment servicing the remote location to an interface device at the remote location. By way of example, the program streams may be part of existing unicast infrastructure in the head end equipment. The head end equipment obtains content for a first channel of the subscription service available to the user at the home location, and inserts the content for the first channel into the assigned program stream to-thereby make that content accessible to the user at the remote location via the interface device. User selection via the remote location interface device of a different channel of the subscription service available to the user at the home location causes the content for the different channel to be obtained by the head end equipment and inserted into the assigned program stream in place of the content for the first channel.

摘要： Virtually-concatenated data traffic is routed in a network comprising a plurality of nodes. For a given traffic demand to be routed from a source node to a destination node in the network, an initial candidate path set satisfying a differential delay constraint is determined by arranging a plurality of paths in order of increasing delay and selecting a particular subset of the plurality of paths as the initial candidate set. A determination is then made as to whether the initial candidate path set is able to support a bandwidth requirement of the traffic demand. If the initial candidate path set is able to support the bandwidth requirement of the traffic demand, the initial candidate path set is utilized to route the traffic demand. Otherwise, the process is repeated for one or more additional iterations, with a different candidate path set satisfying the differential delay constraint being selected for a given additional iteration by application of a sliding-window function to the plurality of paths arranged in order of increasing delay, until a different candidate path satisfying the differential delay constraint is determined to support the bandwidth requirement of the traffic demand.

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.
