What Is Data Plane?

data plane

Did you hear about the data plane? But you are not knowing what it is don’t worry here I will tell you everything about this term in detail. I will help you through the information and the important points which will give you a brief idea about this plane. The operation in cisco of this plane and azure that I will explain so that you will get more help. You will come to know the difference related to the data, control, and management plane.

Let us start with today’s topic which is the data plane. First, we will read about its definition in the following.

What Is Data Plane?

In routing, the data plane definition relates to all of the processes and functions that use control plane logic to forward packets/frames from one interface to another. The data plane function is made up of the routing table, forwarding table, and routing logic. These packets are routed through the router, and frame incoming and outgoing are handled using control-plane logic. 

The term relates to all of the functions and procedures that use control plane logic to forward packets or frames from one interface to another. It is in process of forwarding actual IP packets. It helps in delivering information packets from source to destination.

Data Plane Examples

Here are some of the examples of data-plane given in the following.

  • Secure Shell traffic is being routed to another system.
  • Border Gateway Protocol traffic forwarding

Data Plane In Networking

The DataPlane layer is on a network that has the infrastructure to carry network traffic. The data plane layer is also called the user plane, forwarding plane, carrier plane, or bearer plane. The data-plane functionality in software-defined networks is decoupled from hardware and delivered through software-based network elements. The task of the It is decided by the type. The actual task in it is done based on what is understood.

The forwarding plane moves packages based on the control plane’s designed logic. The router transports plane data frames. In data forwarding, it serves as a decision implementer. In this plane of data, switching is done.

Data Plane Cisco Operation

The data-plane is the routing plane that is in control of switching packets through the router that is process switching and Cisco Express Forwarding. There may be features in it that impact packet forwarding, such as quality of service and access control lists. The Cisco Sd-wan Control Plane Vs Data Plane cloud is built-in authentication. They are encryption processes that maintain the networks and their data traffic. It helps in providing protection and privacy to the system.

Azure Data Plane

It is the forwarding plane that can be managed on Azure. You can store your data and maintain it easily. This is also the place where data is stored. This suggests the data has already been processed into Azure Databricks where you can still extract data from external sources. The sources such as events data, streaming data, IoT data, etc use will need Azure Databricks connectors to link to external data sources outside of your Azure account for storage.

Data Plane Vs Control Plane Vs Management Plane

Let us see what is the difference between the Data-Plane, Control Plane, and Management Plane in the following.

Data PlaneControl PlaneManagement Plane
The term "data plane" applies to all of the functions and processes that use control plane logic to forward packets from one device to another.Both functions and processes that decide which route to use to deliver the packet or frame are referred to as the control plane.The management plane includes all of the features used to control and manage systems.
It is in charge of routing real IP packets. It is also called a forwarding place or user plane.It is useful for creating and managing the IP routing table.There are router components that are used to handle the device using common protocols.
The user plane is maintained with its objectives packets which are delivered from source to destination. The data-plane is the actual forwarding methodThe control plane is to determine how packets can be forwarded. The control plane of a network controls how data is delivered.This control plane is used by firewalls or routers to grant management access to devices through Interface and SNMP protocol to track system status.
The forwarding plane forwards packets based on the control plane constructed framework.The router uses control plane packets to upgrade the routing table.The management plane of a networking device is the component of a system that configures, manages, provides maintenance, and monitoring. 

FAQ

What is the difference between the control plane and a data plane?

Control Plane and Data Plane can be differentiated as given in the following. Let us read about it.

  • The term “data plane” applies to all of the functions and processes that use control plane logic to forward packets from one device to another. Both functions and processes that decide which route to use to deliver the packet or frame are referred to as the control plane.
  • The forwarding plane is in charge of routing real IP packets. It is also called a forwarding plane or user plane. The Control plane is useful for creating and managing the IP routing table.
  • The user plane is maintained with its objectives packets which are delivered from source to destination. The control plane is to determine how packets can be forwarded.
  • The forwarding plane forwards packets based on the Control Plane And Data-Plane constructed framework. The router uses control plane packets to upgrade the routing table.
  • The user plane is where switching takes place. In data forwarding, the control plane makes decisions.

What is the data plane of the network layer?

The Dataplane of a network layer has the design which helps to carry network traffic. The data-plane layer is also called the user plane, forwarding plane, carrier plane, or bearer plane. The data-plane functionality in software-defined networks is decoupled from hardware and delivered through software-based network elements.

What is the data plane and control plane in MPLS?

The Multiprotocol Label Switching MPLS data-plane defines how data will flow from one provider edge router to the next. The dataplane is an independent routing protocol or label exchanging protocol in use. Based on the information in the Label forwarding Information base or forwarding Information base tables, the dataplane routes packets to the right interface. The Multiprotocol Label Switching control plane specifies how notifications are transmitted from one PE router to another. The MPLS control plane is used to build forwarding Information base tables from Routing information Base information and Label forwarding Information base tables based on label exchange protocol.

Why do we separate the control plane and the data plane?

The separation of the data and control planes also allows for the effective use of a single data-plane and simplifies service provisioning through the network function virtualization management and orchestration system.

Conclusion

Here you came to know about the data plane in brief. I told you about the different things that will help you in understanding more details about the control, data, and management plane. The difference between all these three planes was explained above which will help you in differentiating.

You understood the forwarding plane or the user plane what it is in the above information which I described in simple words. Here you must also have got clear answers to some of the frequently asked questions such as why separation of data and control plane is needed. After reading all the important points and terms you must have got an overall idea of the data plane.
