VPN and Traffic Flow
VPN (virtual private network) uses basic telecommunication infrastructure and it allows employees on the move or in a remote location network access. In light of this, it is important to understand how the network traffic flow. The reason for this is that it enables the personnel to have ready measures should anything go wrong. Ideally, the support staff should learn VPN and traffic flow so that if anything happens, the business should least be affected.
VPN relies a lot on tunneling in order to create a private network that could reach across the internet. On any description on how internet works, information is given on how data files are broken into a series of packets. These are then sent and received by all computers in the office or at home that are connected to the internet. Usually contents from the public view are protected by the outer packet that is also made to move within a virtue tunnel. Tunneling of VPN is a basic process that places a packet within another packet before being transported over internet.
In the VPN traffic tunneling, there is a process called encapsulation that involves layering of packets. Computers or other network devices are placed at each end of the tunnel. These ends are known as interfaces. The computers can encapsulate the outgoing packets and at the same time reopen any incoming packets. This keeps the user or the employee at one end of the tunnel and the technician at the other end. The technician can be placed at either and to help configure the interfaces responsible so as to use VPN service tunneling protocol.
The main purpose of VPN traffic tunneling protocol is to add a security layer that will protect each packet while on its journey over internet. It explains how each computer receives and sends data over its internet service provider. To understand this better, try to look at some training modules on how computers use common networks such as Local Area Network to communicate to each other. This will make your understanding of VPN a lot easier.
To understand the VPN tunneling protocol in layman language, look at the process the computer goes through before getting to you. It starts from the shipping company to the vendor at the warehouse then to the shop and finally, to your home. With this understanding, you can learn the loops of how tunneling works to make your work and maintenance easier and also VPN traffic flow.
