Advantages and Disadvantages of Tree Topology

What is Tree Topology?

Tree Topology integrates the characteristics of Star and topology. Earlier we've a bent to saw but in Physical Star configuration, computers (nodes) unit of measurement connected by each other through central hub. which we have a tendency to put together saw in topology, work station devices unit of measurement connected by the common cable referred to as Bus. once understanding these a pair of network configurations, we'll understand tree topology higher. In Tree Topology, the number of Star networks unit of measurement connected exploitation Bus. This main cable looks like a main stem of a tree, and various star networks as a result of the branches. it's put together referred to as expanded topology. local area network protocol is commonly used during this quite topology. The diagram below will produce it clear.



Let’s discuss the advantages and disadvantages of Tree Topology presently.

Advantages of Tree Topology
1. it's associate extension of Star and bus Topologies, so in networks where these topologies can not be implemented one by one for reasons related to quantifiable, tree topology is that the most effective varied.
2. enlargement of Network is possible and easy.
3. Here, we've a bent to divide the whole network into segments (star networks), which could be merely managed and maintained.
4. Error detection and correction is easy.
5. each section is given dedicated point-to-point wiring to the central hub.
6. If one section is broken, various segments do not appear to be affected.

Disadvantages of Tree Topology
1. because of its basic structure, tree topology, depends heavily on the foremost bus cable, if it breaks whole network is halt.
2. As extra and extra nodes and segments unit of measurement different, the maintenance becomes robust.
3. quantifiability of the network depends on the type of cable used.

Advantages and Disadvantages of a Mesh Networking

What is Mesh Topology?

In a mesh configuration, every of the network node, laptop and alternative devices, ar interconnected with each other. each node not solely sends its own signals however conjointly relays information from alternative nodes. really a real network topology is that the one wherever each node is connected to each alternative node within the network. this kind of topology is extremely pricey as there ar several redundant connections, so it's not largely employed in laptop networks. it's ordinarily employed in wireless networks. Flooding or routing technique is employed in network topology.

Types of Mesh Network topologies:-

1)Full Mesh Topology:-

In this, sort of a true mesh, every part is connected to each alternative part. Even once considering the redundancy issue and price of this network, its main advantage is that the network traffic is redirected to alternative nodes if one in every of the nodes goes down. Full network topology is employed just for backbone networks.

2) Partial Mesh Topology:-

This is way more sensible as compared to full network topology. Here, a number of the systems ar connected in similar fashion as in network topology whereas rests of the systems ar solely connected to one or a pair of devices. It is aforementioned that in partial mesh, the workstations ar ‘indirectly’ connected to alternative devices. This one is a smaller amount expensive and conjointly reduces redundancy.

Advantages of Mesh Topology

1) information is transmitted from totally different devices at the same time. This topology will face up to high traffic.
2) although one in every of the elements fails there's continuously another gift. thus information transfer doesn’t get affected.
3) growth and modification in topology is shunned disrupting alternative nodes.

Disadvantages of Mesh Topology

1) There ar high possibilities of redundancy in several of the network connections.
2) Overall price of this network is much too high as compared to alternative network topologies.
3) Set-up and maintenance of this topology is extremely troublesome. Even administration of the network is hard.

Star Topology Advantages and Disadvantages

What is Star topology?

In constellation, all the elements of network ar connected to the central device observed as “hub” which may be a hub, a router or a switch. in distinction to constellation (discussed earlier), where nodes were connected to central cable, here all the workstations ar connected to central device with a point-to-point affiliation. so it should be aforesaid that every laptop computer is indirectly connected to every various node by the help of “hub”.

All the data on the constellation passes through the central device before reaching the meant destination. Hub acts as a junction to connect utterly completely different nodes gift in Star Network, and at identical time it manages and controls whole of the network. looking forward to that central device is utilized, “hub” can act as repeater or signal booster. Central device can also communicate with various hubs of assorted network. unprotected Twisted strive (UTP) coax is utilized to connect workstations to central node.

Advantages of Star topology
1) As compared to constellation it provides manner much better performance, signals don’t primarily get transmitted to any or all the workstations. A sent signal reaches the meant destination once passing through no over 3-4 devices and 2-3 links. Performance of the network depends on the potential of central hub.
2) easy to connect new nodes or devices. In constellation new nodes could also be adscititious merely whereas not moving remainder of the network. equally elements can also be removed merely.
3) Centralized management. It helps in observation the network.
4) Failure of one node or link doesn’t have a control on the rest of network. At identical time its easy to find the failure and troubleshoot it.

Disadvantages of Star topology
1) associate excessive quantity of dependency on central device has its own drawbacks. If it fails whole network goes down.
2) the utilization of hub, a router or a switch as central device can increase the worth of the network.
3) Performance and equally vary of nodes which could be adscititious in such topology is relied on capability of central device.

Network Topology and Types of Network Topologies

Computer network topology is that the strategy various components of a network (like nodes, links, peripherals, etc) unit of measurement organized. Network topologies define the layout, virtual type or structure of network, not only physically but in addition logically. the strategy at intervals that entirely totally different systems and nodes unit of measurement connected and communicate with each other is about by topology of the network. Topology area unit typically physical or logical. topology is that the physical layout of nodes, workstations and cables at intervals the network; whereas topology is that the strategy information flows between entirely totally different components.

In general, topology relates to a core network whereas topology relates to basic network.

Types of Physical Network Topologies

1)  Bus Topology
2)  Star Topology
3)  Ring Topology
4)  Mesh Topology
5)  Tree Topology
6)  Hybrid Topology


Factors to be taken into thought whereas choosing a configuration
1) Scale of your project (in terms of type of components to be connected).
2) amount of traffic expected on the network.
3) Budget assigned for the network i.e. amount of money you are willing to take a position.
4) required interval
