This includes: Planning a new network/service involves implementing the new system across the first four layers of the OSI Reference Model.
[1] The dimensioning process involves determining the network’s topology, routing plan, traffic matrix, and GoS requirements, and using this information to determine the maximum call handling capacity of the switches, and the maximum number of channels required between the switches.
[1] This process requires a complex model that simulates the behavior of the network equipment and routing protocols.
[1] To calculate the correct dimensioning to comply with the above rule, the planner must take on-going measurements of the network’s traffic, and continuously maintain and upgrade resources to meet the changing requirements.
This topic has been actively studied in conferences, such as the International Workshop on Design of Reliable Communication Networks (DRCN).
[3] More recently, with the increasing role of Artificial Intelligence technologies in engineering, the idea of using data to create data-driven models of existing networks has been proposed.
