Inaccurate data can lead to costly downtime and stranded capacity.

Inaccurate. When network diagrams are updated manually, human error is bound to occur.

Resources need to be spent on this job instead of more productive work.

Time-consuming. Network topology diagrams must be manually updated every time you move, add, or change equipment.Spreadsheets and drawing tools are commonly used for network documentation, but they are: Top Challenges of Documenting Network Topologies Reliable network diagrams allow you to save time troubleshooting issues and deploying new equipment so you can focus on more strategic projects. A real-time view of your network helps you maximize the utilization of your existing capacity and forecast when you will run out of capacity. Accurate network documentation enables quick diagnosis in the event of network issues or planned maintenance. Network topology diagrams are used to visually represent a network’s devices and connections, allowing you to picture how devices are devices communicate with each other. Most commonly found in larger enterprises, hybrid topologies offer flexibility and scalability with the downside of often being complex, difficult to manage, and expensive. A network that is comprised of two or more topologies. Since there can be no single point of failure, it is reliable and secure, but it’s complexity results in high costs and lengthy configuration. A reliable topology where the devices are interconnected and data is transmitted by routing (sent the shortest distance) and flooding (sent to all devices). It is reliable unless the central hub fails, but it can be expensive to set up and use. All data passes through a central hub which connects to all other network devices. The network can run faster than in a bus topology and terminators are unnecessary, but a single failure disrupts the entire network and is hard to troubleshoot. Devices are connected in a circular pattern. It is simple and affordable, but vulnerable to downtime for the entire network with difficult troubleshooting. All devices are connected by one central cable with two endpoints. Network diagrams are typically made to represent one or all of the first three network layers (physical, data link, and network) according to the Open Systems Interconnection (OSI) model, collectively known as the media layers.ĭifferent topologies have different impacts on performance and stability. What is Data Center Service Management (DCSM)?Ī network topology diagram is a visual representation of a network’s devices, connections, and paths, allowing you to picture how devices are interconnected and how they communicate with one another.

What is the Federal Data Center Optimization Initiative (DCOI)?.

If available, check the legend to understand what the different symbols represent.

Look for any icons or symbols that may indicate a specific network service like VoIP or video streaming.

Check for any color-coding that may indicate different networks or VLANs.

Identify any security measures that are being taken to protect the network.

Check for arrows that may indicate the direction of the data flow.

Look for any notes or text that may indicate the type of information being transferred on the network.

For example, an arrow may indicate a router and a circle may indicate a switch.

Check for any symbols that may indicate the type of component.

Check for any labels or markings that may indicate the type of connection or the speed of the connection.

In a basic network diagram, this may include Ethernet cables, telephone lines, or radio signals.

Identify the lines that connect the components.

In a basic network diagram, this may include computers, printers, routers, and switches.

Identify the components of the network diagram.

■ A Z-shaped line represents a serial link.Ĭontinue reading here: Extended Star Topology ■ A straight line represents an Ethernet link. ■ A laptop or computer and monitor represent an end user PC. ■ A rectangular box with arrows represents a workgroup switch. ■ A cylinder with arrows represents a router. ■ A cloud represents the Internet or WAN connection. Figure 1-3 shows a typical network diagram.

The network topology is commonly represented by a series of lines and icons. The amount of information and the details of that information differ from organization to organization. The network diagram uses common symbols to capture information related to the network for planning, reference, and troubleshooting purposes. When designing and describing a computer network, you use a drawing or diagram to describe the physical components and how they are interconnected.
