4. BUS TOPOLOGY
• Nodes are connected to a single
communication channel
• Time shared bus
Only one pair of nodes to establish
communication at a time
• Efficient and reliable
• Example
CSMA / CD
Token Bus
5. Structure of BUS Network
• Ability to connect any number of nodes
• Easy to add and remove
• Easy to maintain
6. Star Topology
• Connected to the central HUB
• Dedicated point to point link
• Server provides connectivity for all nodes
• If the server fails, entire network fails
• Easy implementation
• Centralized control
8. RING Topology
• Connected in the form of closed loop
• Unidirectional and Bidirectional
• Pros
Short cable length
Suitable for OFC
Flexibility to add new nodes
• Cons
Single node failure leads to network failure
Difficulty in diagnosing faults
Non adaptability to structural changes
10. MESH Topology
• Exclusive point to point link
• More than one path for data
• Useful when frequent data sent from a node
• Excessive amount of bandwidth
• Inherent fault tolerance
12. TREE Topology
• Another form of BUS topology
• Connected in hierarchical form
• Parent Child relationship
• Root node is powerful
• Ease of expansion, Identification
• Isolation of faulty nodes
• Cons
Highly dependent on the root node
