10 Popular Topics in Networking

Top Topics in Network Engineering

Network engineering, a crucial field within the IT sector, is constantly evolving. With increasing demands for robust connectivity, network performance, and security, it’s essential to keep up-to-date with the latest topics and trends. Here are some top topics that every network engineer should be familiar with:

  1. 5G and Beyond:
    • The 5th generation of mobile networks, commonly known as 5G, promises faster data download and upload speeds, more stable connections, and broader coverage. Beyond 5G, network engineers are already discussing the 6th generation, which will further enhance connectivity capabilities. As these networks evolve, there’s a demand for experts who can design, implement, and maintain them.
  2. Software-Defined Networking (SDN):
    • SDN is changing how networks are designed and operated. By decoupling the network control plane from the forwarding plane, it allows for centralized and programmable control of network traffic. This helps in automating and optimizing network resources and can even adapt to changing business requirements.
  3. Network Function Virtualization (NFV):
    • Closely related to SDN, NFV decouples network functions from hardware, allowing them to run in software. This means that functions like firewalls, load balancers, and routers can be hosted on virtual machines, providing flexibility and reducing hardware dependence.
  4. Network Automation:
    • As networks become complex, manual configurations become a bottleneck and can introduce errors. Automation tools and frameworks, such as Ansible, Terraform, and Python scripting, allow network engineers to deploy, manage, and troubleshoot network devices automatically.
  5. Cybersecurity:
    • With increasing cyber threats, there’s a growing emphasis on network security. Engineers need to understand the latest vulnerabilities, intrusion detection systems, firewalls, and other security protocols to protect organizational data. Zero Trust Network Architecture is a notable model that focuses on never trusting and always verifying all network access.
  6. Internet of Things (IoT) and Edge Computing:
    • The number of connected devices is expected to grow exponentially, making IoT a hot topic. These devices generate vast amounts of data. Edge computing, which processes data closer to where it’s generated (i.e., at the edge of the network), helps reduce latency and ensure efficient data processing for IoT devices.
  7. Cloud Networking:
    • As more organizations move their operations to the cloud, understanding cloud networking becomes paramount. This includes comprehending virtual networks, hybrid cloud integrations, and cloud-native architectures, ensuring seamless operations between on-premises and cloud infrastructures.
  8. Intent-Based Networking (IBN):
    • IBN is a design that captures and translates business policies into network policies. It automates the configuration and monitors the network’s continuous alignment with the intended state. The objective is to have a network that can adjust and correct itself as needed.
  9. Network Telemetry:
    • Telemetry is the process of collecting data from remote or inaccessible points and transmitting it for monitoring and analysis. In networking, telemetry provides real-time insights into network performance, helping engineers make informed decisions and anticipate potential issues.
  10. Quality of Service (QoS) and Network Slicing:
    • QoS is a set of technologies that guarantee the performance of some specific applications or types of traffic over others. As we move towards a more connected world, ensuring certain data packets receive priority becomes vital. Similarly, network slicing in 5G networks allows for the creation of multiple virtual networks on a single physical network, ensuring specific quality and performance levels.

In conclusion, the world of network engineering is in a state of rapid evolution. New technologies and approaches are reshaping how networks are designed, implemented, and managed. Staying informed and adaptable is no longer just an advantage but a necessity for professionals in the field.
