Learn to Create Your Own Network Architecture Diagram
As a network architect, your job is to create the network architecture diagram that will describe and explain the desired physical and logical relationships among all the interfaces and the switches in your network. To do this, you need to know as much as possible about the various pieces that make up the design and how they interact with each other. Network diagrams are the tools that allow you to visualize these relationships and problems. Network diagrams contain very detailed descriptions of each component that makes up the network, and it's very easy to make them from scratch. There are a few things that you should look for when creating a network architecture diagram. Here are just a few things to take into consideration.o Links. Most network diagrams contain a box with a name, and those boxes are referred to as links. Relationships are the connections between elements on the network.
o Routes. Other than links, routes are the paths that the packets take to reach their destination. There is usually one route per element on the network. One of the essential functions of a route is to route traffic from source to target, and it's used in determining how the traffic is routed through the network.o Control plane. The control plane is usually described as a building or tower. This is where the interfaces, switches, routers, and firewalls are located. It's also the place where you will find the various mechanisms that will send information back and forth between the elements on the network.o Physical layer. The physical layer of the network architecture diagram describes how a device on the network is connected to another device, such as a client. It also describes how the network is "piped."o Logical layer. Logical layers contain information from the physical layer. They are used to present a sequence of options for how to create an interface. These are also called "physical options."o Network layer. The network layer describes how the network receives traffic. Network layer names include Ethernet, Token Ring, and Local Area Network (LAN).o Service layer. This layer is used to describe services on the network. The service layer is a series of logical functions, or options, used to generate a set of requests.
