Abstract: A device receives, from multiple network elements, status information for a user equipment (UE) connection associated with a wireless core network and updates, based on the status information received from the network elements, a database record for the UE connection. The device receives, from an application server, a request for information associated with the UE connection and constructs, based on the request and from the database record, a resource message that includes real-time information about the UE connection. The device sends the resource message to the application server. The device also provides a disconnect message to the application server and/or the network elements when the status information received from the network elements indicates that the UE has been disconnected from the wireless core network.

Abstract: An exemplary method includes monitoring a performance of at least one of a plurality of layer-2 network paths connecting a layer-2 network switch device to another layer-2 network switch device and selecting an optimal one of the plurality of layer-2 network paths over which to forward data traffic based on a path selection heuristic and the monitored performance of the at least one of the plurality of layer-2 network paths. At least a portion of the exemplary method may be performed by a layer-2 network switching system. In certain embodiments, the selecting of the optimal one of the plurality of layer-2 network paths over which to forward the data traffic is based on at least one of a latency parameter, a congestion parameter, and a cost parameter associated with the at least one of the plurality of layer-2 network paths. Corresponding systems and methods are also disclosed.

Abstract: Techniques for providing a method and system for multi-layer network analysis and design are disclosed. In one particular exemplary embodiment, the techniques may be realized as a method, comprising determining, using a computer model of a network, a minimum probability of failure path between a pair of network nodes at a first network layer for one or more pairs of network nodes, calculating, using a processor and stored network data, a value for the minimum probability of failure for the identified minimum probability of failure path between the pair of network nodes at the first network layer for the one or more pairs of network nodes. The method may include identifying a maximum of the determined minimum probability of failure values for the one or more pairs of network nodes for the first network layer. The method may include probability of failure calculations for one or more secondary network layers.

Abstract: A communications system provides a dynamic setting of optimal buffer sizes in IP networks. A method for dynamically adjusting buffer capacities of a router may include steps of monitoring a number of incoming packets to the router, determining a packet arrival rate, and determining the buffer capacities based at least partially on the packet arrival rate. Router buffers are controlled to exhibit the determined buffer capacities, e.g. during writing packets into and reading packets from each of the buffers as part of a packet routing performed by the router. In the disclosed examples, buffer size may be based on the mean arrival rate and one or more of mean packet size and mean waiting time.
