I would like to thank everyone for their prompt responses on this matter.
I have managed to achieve what i wanted with the concept of network bonding.
I finally got some time to review all the links which was shared here on this post (especially by @craigcurtin & @lu4t )
I had no idea something like this existed. I have managed to resolve this and now i can have a smooth transitions between my 2 ethernet connections (eth0 and eth1) using this technique.
I went on poking around with our friend "Google" and found this very easy process on how to set this up.
Hope that link is useful to others as it was to me.
Here's @lu4t 's link & @craigcurtin 's link
