  • Patent number: 8565718
    Abstract: In one embodiment, the method includes receiving, by a processor, subscriber usage data for a plurality of subscribers and performance metrics data for a plurality of cells of a wireless network. The method further includes identifying, by the processor, a set of subscribers that have one or more peak usage time intervals that are periodic. The method further includes identifying, by the processor, one or more peak usage time intervals of the plurality of cells in the wireless network. The method further includes classifying, by the processor, a first subset of the set of subscribers based on a correlation of the one or more peak usage time intervals of respective ones of the set of subscribers to the peak usage time intervals of the cell.

  • Patent number: 7872991
    Abstract: Methods and systems for forwarding packets over Label Switched Paths (LSPs) in a Virtual Private Network (VPN) are implemented within a Layer-2 architecture. A system includes a number of multi-purpose nodes connected by a number of multi-protocol label switching (MPLS) LSP links. Each multi-purpose node contains at least one bridging module (BM) that runs an extension of a bridging protocol (BP) contained in the IEEE 802.1d standard. The BP is used to establish MPLS LSPs between the BMs. The BP then generates a spanning tree using a spanning tree program to establish an optimal number of active LSPs. The remaining LSPs are then set to “inactive” The BM de-allocates the resources assigned to inactive LSPs and makes the resources available to other active LSPs.
