SDN (Software-Defined Networking) in Mobile Networks
SDN (Software-Defined Networking) is a key technology in modern mobile networks. Particularly in conjunction with Network Functions Virtualization (NFV), to create a more flexible and agile network architecture.
SDN refers to the decoupling of the control plane and the data plane of the network, allowing for the central control of the network.
This separates the control plane (which makes decisions about routing the traffic) from the data plane (which forwards traffic according to the control plane's decisions). Which allows for a central SDN controller to manage the network, making it easier to configure, monitor, and optimize the network.

5G Core Network Architecture
In this post, we will learn 5G Network Architecture. The control plane in 5G network includes the AMF, the SMF, the AUSF, the UDM, and the PCF. While the user plane includes the UPF. The control plane is not including those network functions only, there are another network functions in the control plane, that will be discussed later. In…

What is 5G CUPS in 5G Network ?
In this post we will learn what is 5G CUPS. CUPS refers to "control plane and user plane separation". 5G CUPS means that the 5G network is separated into "control plane" and "user plane". In order to understand CUPS, first we should know that in order for the UE to be able to exchange user…

5G Network Slicing
5G Network Slicing means that, to divide the physical network that the operator is having, into different logical networks with different characteristics. Every logical network, is a network slice. And every network slice has different characteristics from the other network slices, so that it can serve a certain type of services accordingly. Every network function…
