  • Patent number: 9497661
    Abstract: A method implements a control plane of an evolved packet core (EPC) of a long term evolution (LTE) network in a cloud computing system. A cloud manager monitors resource utilization of each control plane module and the control plane traffic handled by each control plane module. The cloud manager detects a threshold level of resource utilization or traffic load for one of the plurality of control plane modules of the EPC. A new control plane module is initialized as a separate virtual machine by the cloud manager in response to detecting the threshold level. The new control plane module signals the plurality of network elements in the data plane to establish flow rules and actions to establish differential routing of flows in the data plane using the control protocol, wherein flow matches are encoded using an extensible match structure in which the flow match is encoded as a type-length-value (TLV).

  • Patent number: 9167501
    Abstract: A control plane device in a cloud computing system executes a plurality of virtual machines for implementing network function virtualization (NFV). The control plane device is operable to manage implementation of a general packet radio service (GPRS) tunnel protocol (GTP) in a packet core (PC) of a third generation (3G) network having a split architecture where a control plane of the PC of the 3G network is in the cloud computing system. The control plane communicates with a data plane of the PC through a control plane protocol. The data plane is implemented in a plurality of network devices of the 3G network. The control plane device and the plurality of virtual machines are operable to communicate with other control plane devices in the cloud computing system and with the plurality of network devices of the data plane.
