1.2.2 Topology Types - Huawei Talent Online
Bus topology
As the simplest design, a bus topology requires nodes to be in a linear order. Each device in a bus topology setup connects to a single cable. You should note that a bus and linear topology doesn’t transmit data bidirectionally. In other words, the data can only go from one end to the other. As with all other topologies, there are advantages and disadvantages to a bus topology.
Ring topology
Another simple design is the ring topology. As you might suspect, a ring topology is in the form of a circle, where each device has two adjacent nodes. A typical ring topology will have four nodes, but there could be more if the need arises. Ring topologies are versatile and fitting for all sized businesses, and many businesses use them because of their advantages.
Star topology
Unsurprisingly, a star topology’s setup resembles, well, a star. In the center of the star is a central hub that each node connects to. Because of the central hub, star topologies are more reliable than the previous setups and have several advantages. Since each node has its own connection to the central hub, trouble shooting is much easier. Additionally, the performance is faster because data doesn’t have to go through each node before reaching its destination. Finally, if one node fails, the rest of them will still work as normal.
Mesh topology
A mesh topology is like a glorified ring topology. The mesh topology is among the most common setups for businesses for a few reasons, but mostly for its reliability. The reason a mesh topology is so reliable is because each node is connected directly to other devices with point-to-point links. Because the devices connect to other devices in the network, you’ll experience little to no problems caused by data traffic. Additionally, if one node were to fail, the rest of your network will work fine. The interconnected devices also improve security and privacy, something that’s especially important to businesses. The reason mesh topology is secure is because all the connections are point-to-point, ensuring unauthorized users cannot access the database.
Tree topology
Many organizations like to use a tree topology (sometimes referred to as hierarchical topology) because it’s great for Wide Area Networks. A tree topology requires what’s called a root node, which then connect to sub-root nodes, and continue expanding to other nodes as a top-down effect. You can see why it’s also called the hierarchical topology. The primary benefit of tree topologies is that you’re combining the reliability of bus and star topologies. Moreover, troubleshooting is very simple. Although with primary hubs, you guessed it, if one goes down, they all go down.
