  3. 3. What is Topology <ul><li>The pattern of interconnection of nodes in a network is called the </li></ul><ul><li>Topology . </li></ul><ul><li>The factors while selecting a Topology </li></ul><ul><li>Cost </li></ul><ul><li>Flexibility </li></ul><ul><li>Reliability </li></ul>Network topologies
  4. 4. Different Topologies <ul><li>The Star Topology </li></ul><ul><li>The Bus Topology </li></ul><ul><li>The Ring Topology </li></ul><ul><li>The Tree Topology </li></ul><ul><li>Graph Topology </li></ul><ul><li>Mesh Topology </li></ul>Network topologies
  5. 5. Network topologies <ul><li>The Star Topology </li></ul>Client Client Client Client Server
  6. 6. <ul><li>The Star Topology </li></ul><ul><ul><li>All nodes are connected to a central node by a single path </li></ul></ul><ul><ul><li>This is used for data processing and voice communication networks </li></ul></ul><ul><ul><li>Advantages </li></ul></ul><ul><ul><ul><li>Ease of service </li></ul></ul></ul><ul><ul><ul><li>One device per connection </li></ul></ul></ul><ul><ul><ul><li>Centralized control/Problem diagnosis </li></ul></ul></ul><ul><ul><ul><li>Simple access protocols </li></ul></ul></ul>Network topologies
  7. 7. <ul><ul><li>Disadvantages </li></ul></ul><ul><ul><ul><li>Long cable length </li></ul></ul></ul><ul><ul><ul><li>Difficult to expand </li></ul></ul></ul><ul><ul><ul><li>Central node dependency </li></ul></ul></ul><ul><li>The Bus Topology </li></ul>Network topologies Server Client Client Client Client
  8. 8. Network topologies <ul><ul><li>Popular topology for data network </li></ul></ul><ul><ul><li>Single transmission medium onto which various nodes are attached </li></ul></ul><ul><ul><li>Normally coaxial cable is used </li></ul></ul><ul><ul><li>Terminators at both end of BUS absorb signal, removing it from BUS </li></ul></ul><ul><li>The Bus Topology </li></ul>
  9. 9. <ul><ul><li>Advantages </li></ul></ul><ul><ul><ul><li>Short cable length and simple wiring layout </li></ul></ul></ul><ul><ul><ul><li>Resilient Architecture </li></ul></ul></ul><ul><ul><ul><li>Easy to extend </li></ul></ul></ul><ul><ul><li>Disadvantages </li></ul></ul><ul><ul><ul><li>Fault diagnosis is difficult </li></ul></ul></ul><ul><ul><ul><li>Fault isolation is difficult </li></ul></ul></ul><ul><ul><ul><li>Repeater configuration </li></ul></ul></ul><ul><ul><ul><li>Nodes must be intelligent </li></ul></ul></ul>Network topologies
  10. 10. <ul><li>The Ring Topology </li></ul>Network topologies A B C D
  11. 11. Network topologies <ul><li>The Ring Topology </li></ul><ul><ul><li>Each node is connected to two and only two neighboring nodes </li></ul></ul><ul><ul><li>Data is accepted from one neighboring node transmitted to other </li></ul></ul><ul><ul><li>Data travels in one direction </li></ul></ul><ul><ul><li>After passing through each node, it returns to sending node, which removes it </li></ul></ul><ul><ul><li>Advantages </li></ul></ul><ul><ul><ul><li>Short cable length </li></ul></ul></ul><ul><ul><ul><li>No wiring closest space required </li></ul></ul></ul><ul><ul><ul><li>Suitable for optical fibers </li></ul></ul></ul>
  12. 12. <ul><ul><li>Disadvantages </li></ul></ul><ul><ul><ul><li>Node failure causes network failure </li></ul></ul></ul><ul><ul><ul><li>Difficult to diagnose faults </li></ul></ul></ul><ul><ul><ul><li>Network reconfiguration is difficult </li></ul></ul></ul><ul><li>The Tree Topology </li></ul>Network topologies Server Client Client Client Client Client Client
  13. 13. Network topologies <ul><li>The Tree Topology </li></ul><ul><ul><ul><li>Variation of BUS topology </li></ul></ul></ul><ul><ul><ul><li>Tree structure with central root branching and </li></ul></ul></ul><ul><ul><ul><li>subbranching to the extremities of network </li></ul></ul></ul><ul><ul><ul><li>Transmission is same as BUS </li></ul></ul></ul><ul><ul><ul><li>Also known as Hybrid Topology </li></ul></ul></ul>
  14. 14. <ul><li>Graph Topology </li></ul><ul><ul><li>Nodes are connected in arbitrary fashion </li></ul></ul><ul><ul><li>Link may or may not connect two or more nodes </li></ul></ul>Network topologies Machine Machine Machine Machine Machine Machine Machine Machine
  15. 15. Network topologies <ul><li>Mesh Topology </li></ul><ul><ul><li>Each node is connected to more than one node </li></ul></ul><ul><ul><li>This provide an alternate route mechanism </li></ul></ul><ul><ul><li>Excellent for long distance networking </li></ul></ul><ul><ul><li>Supports back-up and rerouting </li></ul></ul><ul><ul><li>Used in large internetworking environments with stars, rings and buses as nodes </li></ul></ul>
