A network-centric modeling mechanism is provided for updating network models in order to mitigate network issues. The network-centric modeling mechanism determines for each component in a plurality of components whether a system parameter in a set of parameters particular to the component has deviated from a predicted system parameter value in a set of predicted system parameter values past a predetermined threshold. Responsive to the system parameter deviating from the predicted system parameter value past the predetermined threshold, the network-centric modeling mechanism generates an event stream indicating a sufficient deviation. The network-centric modeling mechanism determines whether the event stream matches a previous pattern. Responsive to identifying the previous pattern that matches the event stream, the network-centric modeling mechanism preemptively mitigates any related issues in the component or in a related component in the plurality of components using topology-aware indices associated with the previous pattern.

A method, system and computer program product are disclosed for providing content to a communications device. In an embodiment of the invention, a communications network receives a first content portion from a content provider and sends the first content portion to the communications device. The communications network also sends a second content portion to the communications device, and this second content portion is customized for the user of the communications device based on selected information about the user that the communications network has. In one embodiment, the communications network uses the selected information about the user to customize the second content portion for the user, and sends the customized second content portion to the communications device. In an embodiment, the communications network sends the selected information to the content provider, and the content provider uses the selected information to customize the second content portion.

Network management data is managed by determining that a first version and a second version of a set of network management data have been created. The set of network management data is associated with a plurality of managed entities in a network. First and second network graphs are created based on the first version and second version of the set of network management data, respectively. The first and second network graphs include a first and second set of entities in the plurality of managed entities, respectively. A similarity metric is assigned between at least one or more entities in the first and second set of entities. At least a first entity in the first set of entities and at least a second entity in the second set of entities are determined to be identical entities based on the similarity metric being one of equal to and above a first given threshold.

Methods and apparatus are provided for performing byte caching using a chunk size based on the object type of the object being cached. Byte caching is performed by receiving at least one data packet from at least one network node; extracting at least one data object from the at least one data packet; identifying an object type associated with the at least one data packet; determining a chunk size associated with the object type; and storing at least a portion of the at least one data packet in a byte cache based on the determined chunk size. The chunk size of the object type can be determined, for example, by evaluating one or more additional criteria, such as network conditions and object size. The object type may be, for example, an image object type; an audio object type; a video object type; and a text object type.

A method, system and computer program product for managing content distribution in a mobile communications environment. The communications environment includes a core network and a multitude of end-user devices. In one embodiment, the method comprises downloading content from the core network to the end-user devices; and maintaining a map between the end-user devices, the content downloaded to the end-user devices, and the locations of the end-user devices. When a first of the end-user devices requests a specified content, this map and one or more rules are used to identify a second of the end-user devices having the specified content. The first of the end-user devices fetches the specified content from this identified second of the end-user devices. In one embodiment, object location descriptors embedded in the content are rewritten when the content is downloaded to the end-user devices.

A system and method for tracking provenance for software use and development includes a developer toolkit program stored in memory media and accessible by a software market place wherein the software marketplace provides a library of software bundles that can be used for software development and modification of the software bundles. The developer toolkit includes a user interface configured to enable software creation of original works and derivative works. The development toolkit further includes a provenance tracker configured to track provenance of the derivative works and original works wherein the provenance tracker makes the derivative work and the provenance of the derivative work available in the software market place. The provenance tracker includes a software bundle identification module configured to identify and verify ownership of the original works and derivative works by associating an owner of the derivative works and original works with features included in portions of the derivative works and original works.

A method, system and computer program product for disseminating information to mobile communication devices from a content provider via a core network. In an embodiment, the content provider sends specified information to the core network, and the content provider sends an information dissemination policy and a time release policy to the core network. The core network determines a time distribution plan for disseminating the specified information, and disseminates the specified information to one or more of the mobile communication devices in accordance with the dissemination policy from the content provider and the time distribution plan. The core network enables the one or more of the mobile devices to release the specified information to a user or users of the one or more of the mobile devices in accordance with the time release policy from the content provider.

A method and system for detecting and correcting invalid network paths in a network having a plurality of routers and a set of global invariant rules imbedded in the network including querying a subset of a routing table data structure defining network paths wherein said subset includes a plurality of routing table entries and comparing a network routing table entry with an earlier network routing table entry for the same node. The method and system also includes detecting inconsistencies between the newer network routing table entry and the earlier network routing table entry, and invalidating the network entries of the older network routing table that are inconsistent with the newer entries. The method and system also includes reconstructing the routing structure by replacing the invalidated network routing table entries with new routing table entries that minimize violation of the invariant protocols.
