Mesh Topology : Routing
In routing, the nodes has a routing logic, as per the network requirement. Like routing logic to direct the data to reach the destination using the shortest distance. We can even have routing logic, to re-configure the failed network
Mesh Topology: Floading
The same data is transmitted to all the network node, hence no routing logic is required. The network is robust, and the its very unlikely to lose the data. But it leads to unwanted load over the network
Type of Mesh Topology:
- Partial Mesh Topology
2.Full Mesh Topology
-
Advantages:
1.Each connection can carry its own data load
2.It is robust
3.Fault is diagnosed easily
4.Provide security and privacy
Disadvantages:
1.Installation and configuration is difficult
2.Cabling cost is more
3.Bulk wiring is required
Bus topology
When it has exactly two endpoints, then it is called Linear Bus Topology
Features:
- It transmit data only in one direction
2.Every device is connected to a single cable
Advantages:
1.Its cost effective
2.Cable required is least compared to other network topology
3.Use in small network
4.Easy to understand
5.Easy to expand joining two cables together
Disadvantages:
1.Cable fails than whole network fails
2.If network traffic is heavy or nodes are more the performance of the network decrease
3.Cable has a limited length
4.Slower than ring topology
-
Star topology
-
-
Features:
- Every node has its own dedicated connection to the hub
2.Hub acts as a repeater for data flow
3.Can be used with twisted pair, Optical Fibre or coaxial cable
Advantages:
1.Fast performance with few node and low network traffic
2.Hub can be upgraded easily
3.Easy to troubleshoot
4.Easy to setup and modify
5.Only that node is affected which has failed, rest of the nodes can work smoothly
Disadvantages:
1.Cost of installation is high
2.Expensive to use
3.If the hub fails, the whole network is stopped because all the nodes depend on the hub
4.Performance is based on the hub that is depends on its capacity
Ring topology
It forms a ring has each computer is connected to another computer, with the last one connected to the first
-
Features:
- A number of repeater a used for ring topology with large number of nodes. It prevent data loss repeaters are used in the network
- The transmission is unidirectional, but it can be made by directional by having 2 connections between each network nodes it called Dual Ring Topology
- In Dual Ring Topology, two ring network are formed, and data flow is in opposite direction in them.
- Data is transferred a sequential manner that is bit by bit. Data transmitted, has two pass through each node of the network, till the destination nodes.
Advantages:
- Transmitting network is not affected by high traffic or by adding more nodes, as only the nodes having tokens can transmit data.
- Cheap to install and expand
Disadvantages:
1.Troubleshooting is difficult in ring topology
2.Adding or deleting the computer disturbs the network activity
3.Failure of one computer disturbs the whole network
Tree topology
It has a root, node and all other nodes are connected to it forming a hierarchy
-
Features:
- Ideal if workstation a located in groups
2.Used in wide area network
Advantages:
1.Extension of bus and star topologies
2.Expansion of nodes is possible and easy
3.Easily managed and maintained
4.Error detection is easily done
Disadvantages:
1.Heavily cabled
2.Costly
3.If more nodes are added, maintenance is difficult
4.Central hub fails, network fails
Hybrid topology
-
Features:
1.It is a combination of two or topologies
2.Inherit, the advantages and disadvantages of the topologies included
Advantages:
1.Reliable as error detecting and trouble shooting is easy
2.Effective
3.Scalable as size can be increased easily
4.Flexible
