VPN Tunneling Services

The various types of VPN networks are the most direct alternative to the MPLS solution. With VPN networks, traffic is conveyed through a private and encrypted network to the public Internet. Although data traffic is both private and secure, being conveyed to the public Internet network might make information data affected by issues such as latency, packet loss or congestion. Therefore, configuration of VPNs is critically important to have the most of the benefits of them. For this reason, each tunneling protocol is tailored for a different specific tunneling purpose:
In order to meet your business needs, each VPN network that has already been configured by your IT department will be custom made by our experts. In this way, of course, VPN performance and capability will be strictly connected to the IT department’s expert skills. On the other hand, if you decide to rely upon an external VPN service provider, management will be much easier, since both consulting and realization will be furnished by the provider. Here is a thorough analysis from our experts, where you can find detailed information about the pros and cons of each different type of VPN network. With regard to performance, there is simply no comparison between VPNs and MPLS networks. Nevertheless, VPNs are still to be considered a valid solution since they can create efficient private networking networks by applying the most suitable routing.

Our VPNs can guarantee high Quality Service and are compatible with failover. The capacity for automatic failover means that normal functions can be maintained despite the inevitable interruptions caused by problems with equipment. Yet, the real true strength of the VPN is still its excellent value for money: a standard VPN business is about 100 times cheaper than an MPLS.

Cost savings

VPNs enable organizations to use third-party Internet transport to connect remote offices  to the main site, therefore, eliminating expensive, dedicated WAN links and modem banks. Furthermore, with the advent of cost-effective, high bandwidth technologies, such as DSL, organizations can use VPNs to reduce their connectivity costs.

Compatibility with broadband technology

Through VPNs mobile workers and telecommuting employees can have the opportunity of high-speed, broadband connectivity, like DSL and cable or Fiber which provides them with secure connection to the corporate intranet. Broadband connectivity supplies flexibility and efficiency. High- speed, broadband connections are a very helpful means, that allow companies with remote offices to create one cohesive network at a cost.

Security

VPNs can also include a security device that provides network administrators with secure traffic flow. VPNs advanced encryption and authentication protocols guarantee the highest level of security to protect

Scalability

Finally, it should be also taken in consideration this VPNs option by which companies become able to add a large supply of capacity, without any addition of significant infrastructure. By this solution organizations can use the Internet infrastructure within ISPs and devices, and have the opportunity to add new users whenever necessary.

Providing Dynamic Routing Protocols over Layer3 VPN

Dynamic routing is the best choice for large networks like the one shown.

Builds a Topological Map

Link-state routing protocols create a topological map, or SPF tree of the network topology. Using the SPF tree, each router can independently determine the shortest path to every network.

Hierarchical Design

Link-state routing protocols use the concept of areas.

Fast Convergence

When receiving an LSP, link-state routing protocols immediately flood the LSP out all interfaces except for the interface from which the LSP was received.

Event-driven Updates

After the initial flooding of LSPs, link-state routing protocols only send out an LSP when there is a change in the topology.
