Network mapping challenges

Network mapping has helped IT admins gain greater control and visibility over their networks by dividing complex networks into smaller, manageable chunks. It helps in visualizing how different network components such as servers, switch ports, and routers interconnect to carry out their functions. By representing how network devices communicate, network maps offer actionable insights for managing, scaling, and troubleshooting networks. This has also helped IT admins easily run audits, check performance, and ensure the security of mapped network devices.

With that being said, creating and maintaining network maps isn't as easy as it sounds. It requires manual legwork, active network probing, and continual status updates. Network admins depend on a number of network protocols, CLI commands, and point tools to generate network maps. This has created some hurdles to effective network topology mapping and monitoring.

Top 5 challenges with network mapping

Now, let's do a deep dive into each of the above challenges.

Updating network changes as needed—it's not a "set it and forget it" task

Network mapping isn't just setting up maps once and referring back to them whenever needed. Since most networks are dynamic in nature, your network map should also evolve along with your network. Only up-to-date network maps serve their purpose, such as aiding in remote troubleshooting, whereas outdated network maps can be misleading and might not contain sufficient information about mapped devices.

For instance, say that one of your critical devices is facing a networking issue. Using a network map, you identify that this device is connected to a faulty switch port. To ensure the other devices connected to the switch port are not affected, and to connect them to a better switch port, you need to quickly identify all the connected devices. While tracing cables manually can help, it's impractical in scenarios such as remote troubleshooting. This is where network maps boost your troubleshooting ability. However, if your map isn't up to date, then you might miss out on newly added devices while trying to identify and fix devices that have been removed from the network. To avoid this hassle, you have to constantly add, delete, or update mapped devices as your network changes, requiring a substantial amount of manual work and time.

Getting centralized control and visibility into different network maps

It's impractical to encompass all the networking components and their attributes into one network map. Network admins rely on different network maps that are created as needed.

For instance:

  • Physical network maps such as switch port maps and rack views help IT admins understand how their network components are being connected in the network's OSI physical layer. This includes mapping down cables, terminals, and hubs.
  • Logical network maps help visualize network connectivity according to the OSI data link layer.
  • Functional network maps help network admins group and visualize network components as per the networking functions they perform.

These different maps can be created using different approaches such as manual mapping, semi-automated mapping, and fully automated mapping. For example, creating custom network maps of distinct geographies such as business view maps can be done manually. However, manual mapping isn't used to map complex IT environments.

Network admins rely on all different types of maps and mapping techniques to achieve full coverage of their network. This is tedious and ineffective because they have to switch between different tools and solutions to create, view, and manipulate these maps.

Discovering the "whats" of mapped network components

It's not sufficient for network maps to only contain network components and their interconnections. They should also be able to give insights into the networking attributes of the mapped components. For instance, a Layer 2 map should display the IP address, the MAC address, and the status of a mapped device. This helps admins more easily understand the mapped network and enables effective network management.

Nevertheless, most traditional network mapping tools offer surface-level insights or no insights into the mapped components. Network admins are required to correlate data from other monitoring tools to check the networking attributes of the required devices. This causes data collection overhead and is time-consuming.

Adapting to newer network mapping technologies

With networks rapidly adopting newer technologies and networking concepts, traditional network mapping techniques and tools don't make the cut anymore. Even with the use of efficient network mapping software, network admins should ensure that their tools are constantly updated and patched to support new technologies and eliminate the threats of new network vulnerabilities.

For instance, with the advent of cloud technologies and network containerization, network admins should now be able to map physical, virtual, hybrid, and cloud network components.

The need for an integrated approach to streamline troubleshooting

One of the primary uses of network maps is their ability to speed up the troubleshooting process. Effective network maps can aid network admins in several stages of network troubleshooting, including identifying the root cause of a network issue, tracking down the components causing an issue, identifying the connected device, and isolating the affected network region.

The challenge arises when network admins need to collect information and collaborate with their team to resolve the network issue. Often this requires using different tools for network probing, scanning, data collection, task assignment, and team collaboration.
