Virtual Private Network (VPN): VPNs are actually virtual networks that are mainly defined for secure communication over public transmission systems. VPN helps to minimize the expense of leasing private point to point connections. Special VPN protocols are used to ensure whether a VPN can carry all types of data in a private manner. Hence these protocols encapsulate higher level protocols by a process known as tunneling. Routing and remote access service (RRAS): RRAS is actually a remote access server software and VPN solution which was developed by Microsoft. RRAS also implements a VPN and also allows a computer to accept different remote client connections on any transmission path. RRAS software controls data encryption and also routes incoming packets to the destination. Direct Access: Direct access which is also known as unified remote access is a VPN like technology that provides intranet connectivity to client computers when they are connected to the internet. Computers are connected directly when they are connected to the internet in direct access connections. Direct access provides a securely encrypted VPN and also can be deployed for multiple sites.

Program Plan Intro

Virtual Private Network (VPN):

VPNs are actually virtual networks that are mainly defined for secure communication over public transmission systems.

VPN helps to minimize the expense of leasing private point to point connections.

Special VPN protocols are used to ensure whether a VPN can carry all types of data in a private manner. Hence these protocols encapsulate higher level protocols by a process known as tunneling.

Routing and remote access service (RRAS):

RRAS is actually a remote access server software and VPN solution which was developed by Microsoft.

RRAS also implements a VPN and also allows a computer to accept different remote client connections on any transmission path.

RRAS software controls data encryption and also routes incoming packets to the destination.

Direct Access:

Direct access which is also known as unified remote access is a VPN like technology that provides intranet connectivity to client computers when they are connected to the internet.

Computers are connected directly when they are connected to the internet in direct access connections.

Direct access provides a securely encrypted VPN and also can be deployed for multiple sites.
