OVERVIEW

Cisco 1720 VPN Access Router

Flexible, Secure VPN Access for Small and Medium-Sized Businesses and Small Branch Ofﬁces

Market Trends

The Internet is fundamentally changing the way companies

do business. And the future will bring even more change,

driven by rapid changes in networking technology.

Companies who are ready for this future stand to gain

competitive advantage. In the new world of networking,

three key market trends need to be considered when making

decisions onnetwork equipment for small and medium-sized

businesses and small branch ofﬁces: virtual private network

(VPN) capability, ﬂexibility, and network device integration.

VPNs—The New World of Networking

Traditionally, companies connect their geographically

dispersed sites by leasing private WAN connections from

service providers to form a private communications

infrastructure. The resulting networks offer guaranteed

bandwidth with predictable delay, but the company pays a

high price for this bandwidth—regardless of whether they

actually use all of it. This scenario leads to an expensive

infrastructure, with cost being a function of the speciﬁed

bandwidth and distance.

Virtual private networks connect geographically

dispersed sites and remote users together using shared or

public networks—such as the Internet—while providing

security,trafﬁc prioritization, management, and reliability as

good as that of private networks. By utilizing shared, global

networks such as the Internet, VPNs can deliver signiﬁcantly

reduced WAN costs and provide new capabilities such as

secure extranet communication among business partners.

The main beneﬁts of a VPN solution include:

• Reduced cost—Industry analysts and news media report

that VPNs can save recurring WAN costs by 30 to 80

percent (see, for example, Data Communications 9/98,

Network World 8/31/98), resulting in equipment payback

periods of a few months and returns on investment (ROIs)

in the hundreds of percents. For site-to-site connectivity,

VPNs leverage the low cost of intranet access over a shared

infrastructure. For remote-user access, VPNs save

long-distance dialup charges by calling a local number and

connecting over a shared infrastructure for the long

distance. Further, companies can simplify WAN operations

by outsourcing their VPNs to a service provider.

• Extranet communication—VPNs allow business partners

and suppliers to communicate easily and securely, and to

control access to network resources such as databases.

• Improvedconnectivity—TheInternetprovidesglobalreach

for connecting sites and remote dial users. Due to the

Internet’s global popularity and availability, it is much

easier to set up a localInternet connectionwithin a foreign

country than it is to get an international private WAN line

through the country’s telephone company.

• Better reliability—Using the Internet or any large service

provider’s shared network provides automatic redundancy

due to ubiquitous routing nodes.
