There are seven layers on OSI, what is the important layer to optimize the performace the routing performance.

Thank You

I would say all the layers are very important. Each layer has their own functionality to take over. I think most job done by network layer.

Just my 2 cents

Thank you

Your question answers itself. The most important layer for routing performance is the only layer in which routing occurs: Layer 3 (Network Layer)

Of course there is whole lot more to routing performance than just layer 3 info....

Just thought I'd mention that

Hello...

As earlier mentioned that all the layers have their importance. Mostly the Network, transprot and application layers are the most important and very useful layers in routing. Here I have provided one URL that will help you to found the applications of different layers and different way as a pictorial representation:

hi
all the layers are important but the most necessory are data link layer and the physical layer because without these two the data can not be transferred but if we miss the session or application layer the transfer is still possible.

'Important' wouldn't be the word I'd use. I'd say layer 3 the network layer would be the most significant layer in optimizing network performance. Google search 'Layer 3 Switches' and you'll find out how they've integrated routing logic into hardware in switches.

i think there are some layers which you can skip but the most important is network layer becuse it makes it possible to manage addressing and routing of data, i.e. their path via the network

Hi,

Well, I would say that better understanding of routing protocols like BGP, OSPF can help better in optimization of routing performance.
