Q. write a note on mesh Topology

Ans.--> In a mesh network Topology ,each of  the network node computers and other  devices  are inter connected with one another .Every node not only sends its own signals but also relays data from other nodes .

 

--> In fact a true mesh Topology is one where every node is connected to every other node

      in the network.

--> This type of Topology  is very expensive  as these are many redundant connection thus

      it is not mostly used in computer network.

-->  It is commonly used in wireless networks. flooding or routing technique is used in 

       mesh Topology.

-->  Mesh Topology structure .

 

           *Types of mesh Topology .

         1.Full mesh Topology.

         2.Partial mesh Topology .

 

1.Full mesh Topology .

   -->   like a true mesh ,each component is connected to every other component .Even 

          after considering the redundancy factor and cost of this network.

  -->  Its main advantage is that the network traffic can be redirected to other  nodes goes

          Down full mesh Topology is used only for Backbone network.

 

 2. Partial mesh Topology.

    -->Some of the System are connected in smaller fashion as in mesh Topology, while      

         reset of the  system  are only connected to 1 or 2 device .It can be said that partial

         mesh ,the workstations are indirectly connected to other devices .This one is less

         costly and less reduce redundancy.

 

 

Advantages:-

            1.Data can transmitted from different devices simultaneously .This Topology 

                 can with stand high traffic.

            2. Even it one of the component fails there is always an alternative present so data 

                Transfer doesn’t get affected.

            3. Expansion and modification in topology can be done without distributing other

               nodes.

 

Disadvantage:-

               1. There are high chances of redundancy in many of the network connection .

               2. Overall cost of this network is way too high as compared to other network

                  topologies.

               3. set up and maintenance of this topology is very difficult even administration

                  Of  the network is though.

               4. The more computer  that are on mesh network the more cable needed to make

                    Up network.

                     ( x (x-1))-2 : x is the nodes it is used to find number of cable needed mesh      topology.
