Methods and apparatus to monitor server loads are disclosed. An example load monitor includes a first virtual machine to replicate a first server; a router interface to cause a router to redirect a portion of requests destined for the first server to the first virtual machine, the first virtual machine to serve the redirected requests; a collector to collect first metric data from the first virtual machine related to processing of the redirected requests; and an overload indicator to indicate an overload condition at the first server based on the first metric data collected from the first virtual machine.

Methods and apparatus to monitor server loads

Methods and apparatus are disclosed to prevent consecutive attacks on a virtual private mobile network. An example method includes for each of a plurality of network elements, generating virtualized slices based on a virtualized slice count value for subgroups associated with the virtual private mobile network, and assigning non-consecutive ones of the virtualized slices to the subgroups associated with the virtual private mobile network based on demand for the virtualized slices by the respective ones of the subgroups. The example method also includes, in response to a request from a mobile device to access the virtual private mobile network for a first time, assigning the mobile device to one of the virtual slices of the plurality of network elements based on (i) the subgroup associated with the mobile device, and (ii) availability of the virtual slices.

Methods and apparatus to improve security of a virtual private mobile network

Methods and apparatus are disclosed to improve security of a virtual private mobile network. An example method includes identifying a request to initialize the virtual private mobile network, identifying a number of subgroups to associate with the virtual private mobile network, generating a virtualized slice count value based on the number of subgroups, and initializing network elements with a number of virtualized slices based on the virtualized slice count value.

An apparatus and method for performing tunnel signaling over an IP tunneling path are provided. The method includes transmitting an end-to-end signaling flow through an end-to-end path connected to the IP tunneling path, generating a tunnel signaling flow corresponding to the end-to-end signaling flow, and transmitting the generated tunnel signaling flow through the IP tunneling path, wherein the end-to-end signaling flow and the tunnel signaling flow respectively include a binding data object storing binding information for an end-to-end session associated with the end-to-end signaling flow or a tunnel session associated with the tunnel signaling flow.
