The User Plane, also called the Data Plane, carries the network user traffic. A plane, in a networking context, is one of three integral components of a telecommunications architecture. These three elements are the data plane, the control plane, and the management plane. The user plane protocol stack between the e-Node B, and UE consists of the following sub-layers: PDCP (Packet Data Convergence Protocol), RLC (radio Link Control), and Medium Access Control (MAC). The control plane includes the Radio Resource Control layer (RRC) which is responsible for configuring the lower layers. The management plane of a networking device is the element within a system that configures, monitors, and provides management, monitoring and configuration services to, all layers of the network stack and other parts of the system.
