🏷️SDN/NFV in 5G

• SDN was introduced to optimize network management.
• SDN and NFV are key to efficient operations in 5G networks, allowing for customized
  network slices to meet specific requirements.
• Huawei, 5G Network Architecture White Paper
  
• Cisco, The Cisco 5G Strategy Series White Paper
  
• According to 5G white papers, SDN is primarily deployed between the RAN and the Core
  network.
• The SDN Controller manages the flow of data packets through network devices, ensuring
  that traffic entering the 5G core follows the sequence defined in the service chain.
• Within the network slices, Network Functions (NFs) dynamically receive and utilize resources,
  functioning as a network hypervisor to enable this operation.
