What is control and user plane?
Control plane is protocols for which controlling the radio access bearers and the connection between the UE and the network and User plane is responsible for the transfer of user data, such as voice or application data through the access stratum.
What is control plane and user plane in LTE?
At user plane side, the application creates data packets that are processed by protocols such as TCP, UDP and IP, while in the control plane, the radio resource control (RRC) protocol writes the signalling messages that are exchanged between the base station and the mobile.
What is control plane in telecom?
From Wikipedia, the free encyclopedia. In network routing, the control plane is the part of the router architecture that is concerned with drawing the network topology, or the information in a routing table that defines what to do with incoming packets.
What is control plane and data plane?
01. Control plane refers to the all functions and processes that determine which path to use to send the packet or frame. Data plane refers to all the functions and processes that forward packets/frames from one interface to another based on control plane logic.
What is control and user plane separation?
Control-/User Plane Separation (CUPS) [1] in mobile networks refer to the complete separation between control plane functions (which take care of the user connection management, as well as defining QoS policies, performing user authentication, etc.) and user plane functions (which deal with data traffic forwarding).
What is 5G protocol stack?
User-plane protocol stack between UE and UPF [3]. The 5G encapsulation layer supports multiplexing the traffic from different PDU sessions over N9 interface (i.e., an interface between different UPFs). It provides encapsulation per PDU session and carries the marking associated with the QoS flows.
What are LTE protocols & specifications?
What are LTE protocols & specifications?
- Air Interface Physical Layer.
- GPRS Tunnelling Protocol User Plane (GTP-U)
- GTP-U Transport.
- Medium Access Control (MAC)
- Non-Access-Stratum (NAS) Protocol.
- Packet Data Convergence Protocol (PDCP)
- Radio Link Control (RLC)
- Radio Resource Control (RRC)
What is control plane and data plane in Kubernetes?
If the control plane is the brains of Kubernetes, where all the decisions are made, then the data plane is the body. Worker nodes (i.e. VMs) on the data plane carries out commands from the control plane and can communicates with each other via the kubelet, while the kube-proxy handles the networking layer.
What is the main function of the control plane?
The control plane is the part of a network that carries signaling traffic and is responsible for routing. Control plane functions, such as participating in routing protocols, run in the architectural control element.
What is the benefit of control and user plane separation?
Control-/User Plane Separation (CUPS) in mobile networks The main motivation for CUPS is to make user plane functions scale independently, allowing operators for a more flexible deployment and dimensioning of the network.
What is user Plane?
The User Plane, also called the Data Plane, carries the network user traffic. 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.
What is the value of control and User Plane Separation in 5G?
The value of control and user plane separation in 5G is closeness because it allows mobile service providers to bring the service closer to the user. In a traditional 3G/4G network, services are run out of the mobile core, which may be hundreds of miles away from the user.
What is the 5G User Plane function (UPF)?
What is the 5G User Plane Function (UPF)? The User Plane Function (UPF) is a fundamental component of a 3GPP 5G core infrastructure system architecture.
What has developed in the 3GPP control plane?
This paper provides an overview of some specific control plane functionality that has developed in the 3GPP architecture, from GPRS to EPC and now the 5G core network. Innovations of the 5G control plane are considered in the areas of selecting and maintaining the control plane topology, as well as the handling of state within the network.
What does cups mean for 5G Enterprise Services?
Few people, however, are likely to get excited about the idea of CUPS, an acronym that stands for control and user plane separation —yet in terms of 5G, CUPS holds the key to many of the most exciting services. That is the opportunity for 5G enterprise services ideas.
