Case Study: Network performance in a small enterprise(startup) scenario

Load balancing with Cisco 1721

 

It may sound funny in the beginning as to how load balance possible with a entry level router like cisco1721.
It may be easier to do such a thing with cisco 3600 series or above however in startup companies you are with limited resources.

In my earlier tenure with a prominent startup company i had been asked to slove the network performance issue. As a newly appointed system administrator i had several issue which i had very few answers because the situation was messy and there were infrastructure issue and there were people issue on top of it management had little or no technical knowledge. To make the situation worse the one admin guy i am teaming with had by means of his lack of integrity and technical acumen had poor choices made on the infrastructure decisions takeing the network back to stone age.

I want to share here the one decision that saved my life as well as created a scope to build a high performance network with redundant network links making the internet gateway immune ISP failures.
