forwards the data to all other ports. A switch is more sophisticated, in that a

switch can determine the port that each piece of data is supposed to be

delivered to. A switch minimizes network traffic and speeds up the

communication over a network.

Networks take some time in order to plan and implement correctly.

There are many types of scenarios to consider which could affect the

operability of a network.

Introduction to Virtual Private Networking

Virtual Private Networking (VPN) uses a publicly wired network (the

Internet) to securely connect two different networks as if they were the same

network. For example, an employee can access the corporate network from

home using VPN, allowing the employee to access files and printers. Here

are several different implementations of VPN that can be used.

Point-to-Point Tunneling Protocol (PPTP)

PPTP uses proprietary means of connecting two private networks over the

Internet. PPTP is a way of securing the information that is communicated

between networks. PPTP secures information by encrypting the data inside

of a packet.

IP Security (IPSec)

IPSec provides a more secure network-to-network connection across the

Internet or a Wide Area Network (WAN). IPSec encrypts all communication

between the client and server whereas PPTP only encrypts the data packets.

Both of these VPN implementations are used because there is not a
