Abstract

This is an Internet era. Most of the organizations try to establish their development centers and branch offices across the World. Employees working from their homes are also becoming very popular and organizations benefit financially by utilizing less office space, and reducing total expenses incurred by having office workers on site. To meet such requirements organizations develop a need to communicate with these offices over highly secure, confidential and reliable connections regardless of the location of the office. Here the VPN plays a vital role in establishing a distributed business model.
