Cloud computing system and method for implementing control plane of Evolved Packet Core (EPC) in cloud computing system

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 signalsthe 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). 一种方法在云计算系统中实现长期演进（LTE）网络的演进分组核心（EPC）的控制平面。云管理器监视由每个控制平面模块处理的控制平面业务和每个控制平面模块的资源使用。云管理器检测对于EPC的多个控制平面模块中的一个的资源使用或业
