Routing in OSI model,Use of routers .pdf

These are the slides of computer network subject in software engineering about a topic Routing . Routing describes how the router is used in OSI model to transfer data from on e device to another.

1. Introduction to
Routing
Dr Afzal Badshah

2. What is
Routing?
Routing directs packets from source
devices to destination
It make ensure that information
reach successfully
It also make ensure that the
communication is carried out
efficiently and optimally

3. Types of Routing
Static routing Dynamic routing

4. Understanding
Static Routing
Routing table manual configuration
Routing decisions are
predetermined
These decisions are not changed
Suitable for small network

5. How Static Routing Works
•Configuration
•Routing table
•No Adaptability

6. Advantages and Disadvantages
Simplicity Low
overhead
Lack of
Adaptability
Maintenance
Challenges

7. Understanding Dynamic Routing
Adaptive approach to
routing
Inter routers
communicateusing
routing protocols
Dynamic routing table
Suitable for larger
network

8. How Dynamic Routing
Works
•Routing protocol
•OSPF (Open Shortest Path First)
•RIP (Routing Information Protocol)
•BGP (Border Gateway Protocol)
•Exchange of routing information
•Adaptability
•Efficiency in path selection

9. Advantages and Disadvantages
Adaptability Efficiency
Complexity
Resource
Overhead
