What is Internet Traffic Engineering? Optimizing Networks

With the highly connected nature of our world today, millions of packets of information are transmitted via the internet infrastructure each second. When there is no proper regulation of this flow of information, spikes in activities from streaming and cloud services can cause gridlock. Traffic engineering of the internet will be beneficial for network administrators to manage their resources well.

Understanding the Internet Traffic Engineering Process

Imagine your network as a large network of highways. Traffic engineering of the internet would be like a traffic control system in charge of measuring, modeling, and managing flows of information through network paths.

Rather than letting the information packets find a route to move through at their whim, the traffic engineering process utilizes information modeling and analysis to find the best possible route for them.

Key Approaches to Managing Traffic

Traffic management specialists use various techniques to ensure effective data transfer and avoid overloading the servers:

• Load balancing is spreading out all incoming traffic to the data servers or different paths by means of such approaches as Equal-Cost Multipath (ECMP).
• Quality of Service (QoS) approach provides for prioritization of critical data such as voice calls or video conferences rather than ordinary file downloads.
• Route optimization implies the use of intelligent routing protocols that can choose optimal routes using criteria such as bandwidth and latency. Such protocols are OSPF and BGP.

The Role of Software-Defined Networking (SDN)

In today’s Internet traffic engineering, the concept of Software-Defined Networking (SDN) is widely used. The idea of SDN is to isolate the network’s control logic from hardware.

As a result, network administrators obtain the ability to program the process of traffic routing. The resulting separation of architecture provides engineers with visibility into all connected devices, allowing them to manage data flow in an optimal way to avoid bottlenecks and optimize the utilization of network resources.
