Common network diagram symbols: a quick reference guide
5 types of network topologiesIf you’ve ever studied the history of networking, you’re likely familiar with many of the following network topologies. When designing a network today, realize that many of the following topologies, such as a ring and bus topologies, are no longer considered an efficient way of architecting a network.
Examples of network diagramsHow network diagrams can benefit organizationsThere are several positive benefits from creating and maintaining good network diagrams. First, network diagrams are a critical part of any change management process. If you ever need to change anything, like adding a new switch or a new link to a remote office, you’ll need good documentation to understand how the traffic will flow through these new pieces of the network. This will help ensure the new network is stable and efficient. Second, network diagrams are a key piece of documentation required for compliance. Auditors, such as those for PCI compliance, always want to see that you’ve accurately documented and diagramed your network topology. Specifically, they need to know where the firewalls, switches, and server resources are, and all the different ways that someone could get into the network. If you ever need to submit this kind of information to an external audit, or if there were ever a serious problem with your network and you needed to defend the design to management or bring in external consultants, having good and current diagrams will always help your case. Finally, network diagrams are a valuable component of any network troubleshooting process. When you’re faced with a “network is slow” or “network is down” problem, whether reported by a user or noticed by your network management software, having updated network diagrams allows you to immediately understand the context behind the issue. This includes what servers, applications, and users may be impacted, along with the relevant network devices along the logical and physical paths to help direct and accelerate your troubleshooting. Good network diagrams are not difficult to make but can be a time-suck due to the commitment required to discover and inventory all of the assets in the network. Because of this, up-to-date and accurate network diagrams are a rare find. Auvik is a particularly useful tool for automated network mapping. It does a comprehensive job of laying out your network topology with endpoint-level visibility, far deeper than most other systems and manual topology maps. Reacting to network changes as they happen, Auvik’s network topology maps ensure you always have the up-to-date network topology at your fingertips. — |
