How does a Virtual Private Network (VPN) work?

Example 1: Remote Network Access

"Road Warrior A" is on company business in Los Angeles, California. He needs to check his e-mail and respond to important messages, as well as download a brochure for a client from the corporate Intranet in Chicago.

Using an 800 number designated for the corporate network, Road Warrior A dials in and spends three hours on the network. The company pays for long distance phone charges. Cost: approximately $20.00.

With a VPN connection, Road Warrior A uses a local Los Angeles number to dial up a local Internet Service Provider (ISP). He automatically connects to the corporate network via the Internet, using the VPN software installed on his laptop. Cost: $0.00.

Number of Road Warriors	Network minutes per month (20 days/2 hours each)	Long-distance cost per month ($0.10 per minute)	VPN cost per month (average ISP cost of $20 per user)
5	12000	$ 1,200.00	$ 100.00
10	24000	$ 2,400.00	$ 200.00
20	48000	$ 4,800.00	$ 400.00
50	120000	$12,000.00	$1,000.00

Example B: Branch office network access

A company has a main office and three domestic satellite offices. The satellite offices need immediate, full-time access the corporate network. For dedicated frame relays or leased lines, at a speed of 128K, the company pays approximately $800.00 per month per branch office, for a total monthly cost of $2400.00.

With a VPN connection, the branch offices connect to headquarters using VPN routers to connect to the Internet. The company pays approximately $350.00 per office per month, for a total monthly cost of only $1050.00.

And the company can pay as little as $100.00 per office per month, by using a VPN in conjunction with a Dedicated Subscriber Line (DSL) or cable modem (at speeds of up to 786K), for a total monthly cost of just $100.00.

Speed	Cost per month with dedicated or leased lines	Cost per month with dedicated Internet connection	Cost per month with DSL or cable modem**
128K	$ 800.00	$ 350.00	$ 1,200.00
386K	$1200.00	$ 500.00	$ 2,400.00
512K	$1500.00	$ 600.00	$ 4,800.00
784K	$2000.00	$ 800.00	$100.00
1.5MB	$2500.00	$1200.00	$200.00
