Distance Vector Protocol vs Link State Protocol

Fig 1: Distance Vector Protocol vs Link State Protocol

Distance Vector Protocols

These protocols are the protocols that are used to determine the best path for the packets on the basis of the distance and these protocols are the protocols that measure the distance by the numbers of the layer 3 device that is router. In distance vector protocols only complete routing table will be transmitted and this process will consume the large bandwidth factor. In most cases if the bandwidth of the link is low than on that link there is a chance to occur congestion.

Link Sate Protocols

These protocols are the protocols that work on the basis of the characteristics of the route like as the bandwidth, cost and also congestion for the determination of the best path and that's all done on the algorithm that is known as the "Dijkstra Algorithm" that is also known as the link state algorithms. In link state protocols only change will be transmitted and this process will save the large using bandwidth factor. So here below is the difference between the distance vector protocol and link state protocol:

                            Comparison Table

1	Distance Vector Protocol	Link State Protocol
2	Distance Vector Protocols are not scalable routing protocols.	Link Sates Protocols are the scalable routing protocols.
3	These are suitable for the smaller network.	These are suitable for the bigger network.
4	Neighbor to neighbor information move means one to one.	Flood information move means multicast or broadcast.
5	Convergence is slow of these protocols.	Convergence is fast of these protocols.
6	Complete routing table will be transmitted.	Change will be transmitted.
7	Cannot connect establishment.	Connect establishment but this not three-way handshake.
