Extending the Network into the WAN & VPNs and their Benefits

Extending the Network into the WAN & VPNs and their Benefits:

For the most of the services in the service networks, WANs are most widely used which are provided the means for the various users to access the resources around the wide geographical area. And some other services are mainly considered as a Layer 2 type of connections in between the remote locations and mainly around the telephone companies and over its switches. And in this some of the switches are included in the serial point-to-point connection which was a leased line and it’s a Frame Relay Connections.

In this the other type of connections are leverage to the internet infrastructure and then a Layer 3 is an alternative to interconnect the various remote connections and its locations to the organizations. And to provide a protected and security across the all the public internet, and in this we can implement a virtual (VPN) private network solution.

Introducing the solutions for VPN:

For connecting the offices, home offices, business partners sites, and in the remote telecommunications to all the different portions of the company the Cisco VPN solutions are provided using the Internet-based WAN infrastructures. And considering the cost effective, high-bandwidth internet connectivity which was secured by the encrypted VPN tunnels, and the cost can be reduced in the WAN bandwidth and the connectivity can be gradually increases the speed.
By using and integrating the advanced network routing and its intelligence, there the Cisco VPNs are reliable the transport complex of the mission-critical traffic, mainly as the voice and the client server applications, without any compromises of the communications in the security and in the quality.

In between the public and the private networks the VPNs are the encrypted connection mainly acts as an Internet. In this the V stands as a virtual, and the N stands as a network. And then the information is transported from the private network to the public network in a much secured line in the form of a virtual network. The P stands for the private. The traffic is then encrypted in order to keep the data to be confidential and which to remain in the private. In these to form a virtual connection which are routed through the internet in the private network of a company to the employees host or the remote site VPN uses the IPsec instead of using the virtual connections. The following image shows the example of the using the VPNs which are connected to the different and various types of the remote sites.

• Cost Savings: The organizations which uses the more form of the cost effective third party internet to which transports and connects the remote areas like the offices and through the remote users to the main corporate site and thus helps them to eliminate the link expensive and dedicated WAN links and the modem banks.

• Security: By using the advance authentication and the security VPNs protect the data from the unauthorised user access can be very strictly implicated.

• Scalability: with in the VPNs enable the users can access the internet within the ISPs and the devices, and thus makes to enable new sort of users, and thus there the corporations are used in adding the large amount of capacity and by without adding the certain significant infrastructure.
