The first reason might be to reduce bandwidth costs by preferring particular paths (different transit providers). In other words, traffic engineering includes not just the application of technology but also . Origin and destination study IV. Traffic Engineering utilises principles of Engineering to ensure a secure and efficient movement of people and materials on several modes of transport and road networks. Multi-Protocol Label Switching (MPLS) was created to improve packet performance in the core of the networks and is widely used for that purpose. Edge Fabric has been in production for the past several years, steering egress user traffic from our PoPs around the world. You make the best predictions you can about how traffic will flow across your network, and you then order the appropriate circuits and networking devices (routers, switches, and so on). In a 5G environment, service providers will be introducing more services, managing higher bandwidth demand and experiencing accelerated rates of change in traffic patterns - meaning the need for traffic engineering . Network traffic may also be referred to as data traffic or just plain traffic. There are various modes of transportation, inland, and outland that have evolved into the modern-day system.
