A data communication network controls the amounts of virtual network elements it uses. A control system processes user data packets from multiple wireless base stations to determine amounts of user data packet tunnels for a plurality of Quality-of-Service (QoS) levels. The control system processes the amounts of the user data packet tunnels for the QoS levels to identify a target amount of virtual packet gateways to serve the user data packet tunnels. A virtual network element system implements the target amount of the virtual packet gateways to serve the user data packet tunnels at the QoS levels with the virtual packet gateways.

Control of long term evolution (LTE) virtual network elements based on radio network tunnels

An LTE network, having a plurality of base stations and S-GWs, processes GTP packets to determine an amount of GTP tunnels between the base stations and the S-GWs gateways. The LTE network processes the amount of GTP tunnels to determine a target amount of LTE P-GWs to serve the base stations. If the target amount of the LTE P-GWs is greater than a current amount of the LTE P-GWs, then an additional amount of virtual LTE P-GWs is implemented to serve the base stations. If the target amount of the LTE P-GWs is less than the current amount of the LTE P-GWs, then an extra amount of the virtual LTE P-GWs that serve the base stations are removed.

A method of allocating ATM connections is described. The first step of the method includes determining a first bandwidth for the ATM connection based on a number of calls for the ATM connection and an estimated bandwidth per call. The estimated bandwidth per call corresponds to a maximum bandwidth required for a call. Another step includes determining an overbooking factor for the link over which the ATM connection will be allocated. Another step includes adjusting the first bandwidth based on the overbooking factor to determine a second bandwidth. Another step includes determining if the link has at least the second bandwidth available. Another step includes allocating the ATM connection for the second bandwidth if the link has at least the second bandwidth available. Another step includes denying the ATM connection if the link does not have at least the second bandwidth available.
