The transport layer is responsible for transporting the data. The network layer delivers data to the data link layer in a ready-to-transmit state.

The software and devices functioning at the network layer level retrieve packets from a source and establish the route they’ll take to their final destination. The network layer determines the logical addressing and the direct path of every single communication. This layer is also used by wireless (IEEE 802.11) technology and the Address Resolution Protocol. In an enterprise network, the Ethernet usually serves as the container, with most WAN providers using it to transmit your service. The Data Link LayerĪlso called the logical link layer, this takes protocol data units, or PDUs, that have been transferred by the network layer and prepares them to be transmitted by a container. Equipment location will affect your service quality. This is one of the most important layers for the network design process, especially if you’re designing a network for a large, enterprise-scale environment. At the level of this layer, IT administrators or network designers should be focusing on ensuring devices are connected appropriately and there isn’t too much distance between connected devices. The physical layer also encompasses the wireless and electric signals. This includes computers, cables, routers, printers, laptops, and everything in between. The Physical LayerĪs its name suggests, this layer refers to all the hardware and equipment on your network that can be physically handled.

Knowing how these layers work will contribute to your understanding of how to design a network. When it comes to network topology, the lower levels of the OSI model are the most important, so this guide will focus on the first four layers. Network design will typically include the cabling structure, a logical map of the network to be implemented, the quantity of network devices, the type of network devices, the location of network devices, the IP addressing structure, and the network security architecture.Īt the heart of all network design is the OSI network model, which comprises seven layers: The design process is typically depicted in the form of a network diagram, which is the blueprint for the physical implementation of the network. Network design is a complicated process involving evaluating and scoping the network to be implemented. It happens before the network infrastructure is fully implemented.
The network design phase is normally executed by specialist network designers, IT administrators, engineers, or other IT professionals. The phrase “network design” refers to how network infrastructure is planned and structured. In a critical situation where rapid troubleshooting is required, effective network design and topology mapping can make all the difference. With a topology map, identifying faulty devices becomes faster, more accurate, and less stressful. By creating a robust topology structure, you can establish a network that prevents single points of failure and minimizes bottlenecks. This is why you need a topology map, which will give you visual insight into your network’s exact structure.Ī topology map is useful in gaining an in-depth understanding of how your hardware communicates and the speed at which packets are transferred and how this impacts quality of service. Without a comprehensive understanding of how your network components fit together, service quality maintenance becomes extremely difficult. Skip to The Best Network Design Software list > The Importance of Network Designīecause network design serves as the foundation for effective network monitoring, it directly informs your ability to maintain service quality. SolarWinds®Network Topology Mapper ranks highly because it offers an impressive range of advanced utilities-including automatic network discovery and multiple discovery method options-delivered through a user-friendly interface. This guide provides network design help along with a list of the best network design tools currently available. As such, understanding your topology and how to design a network appropriately is key to your network’s success. Your topology structure will be the foundation for conducting quality of service monitoring and troubleshooting, so having a strong awareness of how your topology works is crucial. The way a network is designed impacts your network monitoring capabilities and your overall system performance, making it as important a factor as the infrastructure itself. Network design is a crucial aspect of any enterprise-grade network.
