When networks become mission-critical for business processes, IT professionals' design decisions can have far-reaching consequences. An excellent Network Infrastructure Design of your computer network infrastructure is the foundation on which you want to create your computer system environment. If the Network Infrastructure Design is terrible, no matter how well you design your computer system, the system will not function efficiently due to network congestion. A well-planned network will outperform others. It will be more secure, robust, and troubleshoot with ease, as well as scalable and adaptable to future technology.
A network infrastructure design is not the same as a network topology, although network design includes business processes and outcomes, the network topology is the design as seen through network diagrams, also known as topology maps. Network topologies include ring, chain, tree, and mesh.

Ethernet Network Infrastructure Design
The type of LAN cable used determines the Ethernet in Ethernet in the Network Infrastructure Design. The most common is 10BaseT, which works at 10 Mbps through twisted pair cable and uses baseband signaling. Hubs or repeaters can be used to connect segments in a cascading star topology, but the number of segments and repeaters you can connect is limited.
Ethernet networks can be configured to operate both Half-duplex and Full-duplex.
Half-duplex systems: Use the same physical or logical route for both sending and receiving data by basic hubs or repeaters,
Full-duplex systems: In Network Infrastructure Design, full-duplex Ethernet provides independent routes for transmitting and receiving, hence eliminating collisions. The full-duplex operation needs dedicated switch ports for each device.
There are 2 more Ethernet Network Infrastructure Design types: Fast Ethernet Network Infrastructure Design and Gigabit Ethernet in Network Infrastructure Design.
Fast Ethernet Network Infrastructure Design
Most of the architectural design is identical to Ethernet for compatibility. It is another variation of the Ethernet standard. Fast Ethernet uses the same media access mechanism, topology, and frame types as standard Ethernet. The following are Fast Ethernet standards that use either twisted pair or fiber-optic lines and run at 100 Mbps. The types of Fast ethernet are 100BaseTX, 100BaseT4, and 100BaseFX. All of the hardware, including the NICs, Hubs, and Switches, is Fast Ethernet compatible.
Gigabit Ethernet in Network Infrastructure Design
Gigabit Ethernet has a data throughput of 1,000 Mbps (1 Gigabit). 1000BaseT has a maximum length of 100 meters since it uses the same Category 5 twisted pair cable as Ethernet and Fast Ethernet.
Gigabit Ethernet can also be used in Network Infrastructure Design as a high-speed backbone or for LAN-to-desktop connections for bandwidth-intensive devices. Nevertheless, while using Gigabit Ethernet, only one repeater is permitted between any two devices.
Segmentation in Network Infrastructure Design
In your Network Infrastructure Design, segmentation is particularly beneficial in isolating traffic to a segment, preventing undesirable traffic from crossing over to another segment, or delaying WAN connectivity. When the network grows, network traffic grows to the point that data flow slows and when approached to the architectural design limit, restricts network expansion.
When segmentation in the network infrastructure is done, architectural limitations will be overcome, and congestion in the network will then be reduced, can connect several networks, and can integrate with different networks.
