Thank you for watching our video on Network
Visualization.
Network visualization refers to the process of
producing and showcasing graphical representations of
network devices, connections, and device details.
Numerous forms of network visualization exist,
including network maps, graphs, charts, and matrices.
If you’ve ever found yourself in a situation where
sharing your screen was the easiest way to communicate
your point, you’ll appreciate the benefits of network
visualization.
Network visualization embodies the sentiment, “a
picture is worth a thousand words.”
Network visualization enables administrators to
rapidly and intuitively assimilate extensive
information about the network’s state.
For instance, a network map can deliver a
comprehensive topology overview, elucidating both
physical and logical data flows.
Charts and graphs that depict network data over time
are instrumental in identifying trends and
facilitating capacity planning.
Matrices and network topology maps can unveil
dependencies crucial for troubleshooting and resolving
outages or bottlenecks.
Let’s delve deeper into the core benefits of network
visualization:
Network topology maps offer complete visibility into
your entire network, enabling you to comprehend the
network architecture and device dependencies
intricately.
Dynamic network maps, unlike their static
counterparts, automatically update when changes occur.
Without visibility, problem-solving
becomes an uphill battle.
Network visualization techniques, like maps and
performance graphs, provide the necessary visibility
to streamline troubleshooting and root
cause analysis efforts.
When you understand your current network dependencies,
inventory, and resource utilization trends, planning
for network upgrades and refreshes becomes simpler.
Speed and understanding new scenarios are two key
components to effective onboarding in network roles.
An accurate network topology map can expedite the
process by providing a new network engineer with a
comprehensive view of the network, detailing device
and cable connections, both logical and physical.
Accurately and succinctly conveying complex
information in a manner that customers, managers, and
engineers can understand and act upon is
a formidable challenge.
The appropriate visuals can substantially enhance
clarity, enabling you to address
specific problems effectively.
Network visualization can take many forms.
In this section, we will discuss charts and graphs,
dashboards, and network maps.
Charts and graphs excel at visualizing trends and
comparing data sets.
In terms of network visualization, there’s a plethora
of charts and graphs that can aid in comprehending
your network’s health.
Metrics such as interface utilization, bandwidth, and
packet loss can be graphed over time, while charts can
compare metrics between devices,
interfaces, or time periods.
To transform useful information into actionable
insights, it must be easily accessible and digestible.
While not a distinct type of network visualization,
dashboards aggregate crucial data on a single page,
simplifying the consumption of important information.
A custom-designed dashboard should be information-rich
yet intuitive, allowing for a swift
understanding of vital data.
A default dashboard should provide information on open
alerts, detected misconfigurations, and a graph of top
device utilization among other metrics.
Network maps remain one of the most favored types of
network visualization, and rightly so.

Network maps include physical and logical connections,
rack locations, and floor plans and are categorized
into two types: static network maps and dynamic
network maps.
Also known as network diagrams, static maps can be
created by hand using tools like Visio, or LucidChart.

Static network maps can also be automatically
generated by software tools like U V explorer.
Coupling network discovery with network mapping
presents the advantage of creating snapshots of a
network’s actual state.
Dynamic network maps incorporate real-time data on
network changes.
Dynamic network maps are interactive, allowing a
drill-down to view specific metrics on connections,
devices, and traffic flows.
Given the automation of the discovery and
visualization processes, dynamic network maps tend to
offer a lot of detail.
