A Virtual Private Network (VPN) is a network that allows the private networks at a remote location securely connect to the public Internet and provide access only to the intended recipients for transmitting data. VPN is built by creating the virtual point-to-point connection using the dedicated connections, traffic encryption or virtual tunneling protocols. This example was created in
It is the default PPTP/L2TP/SSTP/OpenVPN topology. A VPN tunnel on a shared IP is protected from many incoming threats. It is great on mobile devices or when added security/privacy is needed. When you use a VPN connection with a shared IP address you connect to a private network with our firewall in front of it safeguarding your device from How Does a VPN Work - Cisco A virtual private network (VPN) extends a company's network, allowing secure remote user access through encrypted connections over the Internet. This allows VPN traffic to remain private as it travels between devices and the network. As a VPN user browses the web, their device contacts websites through the encrypted VPN connection.

The network is robust, and the its very unlikely to lose the data. But it leads to unwanted load over the network. Types of Mesh Topology. Partial Mesh Topology : In this topology some of the systems are connected in the same fashion as mesh topology but some devices are only connected to two or three devices. An example of a company that needs a remote-access VPN is a large firm with hundreds of salespeople in the field. Another name for this type of VPN is virtual private dial-up network (VPDN), acknowledging that in its earliest form, a remote-access VPN required dialing in to a server using an analog telephone system.
A remote-access VPN allows individual users to establish secure connections with a remote computer network. Those users can access the secure resources on that network as if they were directly plugged in to the network's servers. An example of a company that needs a remote-access VPN is a large firm with hundreds of salespeople in the field. Another name for this type of VPN is virtual private
The Mesh Topology This type of network topology boasts the highest fault tolerance of all of the network topologies, it is also usually the most expensive. In a mesh topology, each device/PC is connected to every other device/PC in the network by its own cable (see fig 1.2 below), which means vast amounts of cables for any sizeable network. Each network topology must have at least one data center. To configure data centers for a network topology, follow these steps: Select Configuration Network Design and then click Create Network Design (which displays if you have not yet created a network topology) or Manage Network Design (which displays if you have created a network topology).
