Routing

1. Unit IV
Routing Algorithm:
 Routing is the process of selecting a path for traffic in a
network or between or across multiple networks.
There are three main types of routing algorithms:
1. Distance Vector (distance-vector routing)-DVR
2. To link state (link state routing)-(LSR)
3. Path to vector (path-vector routing)-(PVR)
Routing Protocols:
1. RIP(Routing Information Protocol)
-It identifies the availability path between source and
destination(or)sender and receiver
-DVR Algorithm used in this protocol

2. 2.Open Shortest Path First Protocol(OSPF)
-It identifies the shortest path in the network
-Link state Routing protocols used(LSR)
