What is tree topology?
A combination of bus topology and star topology is called Tree Topology. In a bus network topology, different nodes are linked to a cable, and in a star network topology, all nodes are associated with a central hub. Various star topologies are connected through the primary bus backbone cable to form a tree topology and used for network expansion.
Characteristics of Tree Topology
- Better Flexibility and Scalability
- Used in Wide Area Network.
- Ideal if nodes are located in groups.
- Node expansion is fast and easy.
Finding a fault in the network is easy, and the administrator can fix the error immediately. If there is a problem with any parent node, the child node will stop accessing the data. Since the child node can become the parent node of the future node, the tree network can be easily expanded.
Tree Topology Definition, it is a superior type of building a network in which many linked elements are organized like branches of a tree. For example, tree topologies are often used to hold information in computers or databases in a company network.
Users have many servers on the network using Tree Network Topology. The tree topology is in a hierarchical pattern, in which every level is linked to the next higher level. However, it joins multiple star topologies to other star topology networks. When the network is more extensive than the smaller network, the tree topology is the best, because using a tree topology wastes cables.
When choosing a topology, you must consider the following:
Money: Money is the most significant factor in networking; the user must look if the topology is costly or not.
Length: The length also matters, so you should have to consider it as well.
Cable: Different Types of cable are present, which are used in the topology.
Features of Tree Topology
- High reliability and fault tolerance. The failure of one or more computers will not affect the work of the entire computer network.
- Due to the use of Switch or Intelligent Hub, the network performance is indeed excellent.
- Tree topology provides high security. This security has been further enhanced when using Intelligent Hub.
- You can easily expand the network tree topology to add more and more computers. This can be easily done by extending Star Networks connected to the backbone cable.
- For your small LAN tree topology, it is indeed a good choice.
Example of tree topology
Combining a star network topology and a central bus backbone, dissimilar floors can be connected to each other.
- The B-tree looks the same as the tree topology, and it is used in different programming languages (such as Redis, MySQL, and PostgreSQL).
- If your department is small and even has sub-departments, then this topology is very useful for your organization. Similarly, if you have a team layout on multiple floors, then it may be your best choice. If you try to use a basic star network solution, it will cause you many problems. In this case, it is damaging to transfer the cable from one layer to another. This will cost you too much.
Applications of Tree Topology
However, its use is entirely up to you. Not only can you use it, but you can also benefit from it. We often regard Zigbee as an application of tree topology. But let me tell you the fact that Zigbee does not use a tree topology. Instead, it is based on the concept of mesh network topology.
If you have a multi-story building and want to define a network cluster in each section, you can use it.
Most offices are divided into departments and sub-departments. Therefore, you can use multiple switches to isolate the entire tree network. This makes the whole network tree easier to manage and maintain.
Cases of Tree Toplogy
Cluster tree topology
Cluster tree topology is a case of the tree topology, therefore in a Cluster tree topology, a parent with its children is called a cluster. So, a complete parent-child set is referred to as a cluster. But in most cases, the central device is mostly designated as a parent. Each cluster is known by cluster identification number. Cluster tree topology in ZigBee, ZigBee, does not support cluster tree topology, but the IEEE 802.15.4 supports it.
Spanning tree topology
Spanning Tree Topology covers multiple Backbone Cables for linking numerous clusters present in the whole Computer Network. If we are to minimize communication costs and overheads, we can even apply the Minimal Spanning Tree Algorithm for this purpose.
The Spanning Tree Protocol (STP) is a protocol in the networking, which shapes a loop-free logical topology for Ethernet networks. So, the main function of STP is to avoid bridge loops and the broadcast radiation.
Topology Phylogenetic Tree
The phylogenetic shape is composed of two attributes, namely topology and branch length. Topology is a specific branching pattern of the tree. The marked topology represents the relationship between the taxa. Phylogenetic tree topology has aroused long-term attention in both mathematics and evolution. Unlabeled topology has no taxon at the front end, so it consists only of abstract trees.
Fat Tree Topology
The fat-tree network topology looks like the tree topology; in the tree topology, we have the same terms, such as “root,” “parent,” and “child,” and so on. Mostly used to join a large number of physical computers/servers in huge data centers. The fat tree topology is established on a complete binary tree.
In this, the number of links that enter a switch in a given layer of the topology is equal to the number of links that make the switch come the next layer.
The tree topology is a collection of rings. (T/F)
Tree Topology Advantages and Disadvantages
- The error detection is easy.
- Node expansion is easy and fast.
- Tree topology is easily maintainable and manageable.
- It delivers fault identification and easy maintenance.
- It is reliable, highly flexible, scalable, and secure.
- If one node fails, it never affects the network.
- Performance is outstanding as compared to a simple bus topology network.
- Heavily cable is used and high Cost.
- If the bulk of nodes are added, then the maintenance will be complicated.
- In case of problem in backbone cable whole network stops functioning.
- A large amount of Cost is required for construction and spreading tree networks.
