Site-to-site VPNs are virtual private networks that allow you to connect to different offices from one main location. They work by creating a tunnel between two networks and performing IKE negotiation and decryption between the two networks. In addition, they offer higher performance than other types of WANs. This makes them an ideal solution for businesses that need a secure connection without the expense and complexity of a wide-area network.

Dynamic routing protocol

Site-to-site VPNs are VPNs that connect two locations through a secure tunnel. They can be used to connect two separate networks, whether they are physical or virtual. Using these types of VPNs allows you to connect to two different networks without leaving your home network. This type of VPN also protects your private information.


Permanent connection between offices

Site-to-site VPNs allow you to establish a secure connection between two different locations. These technologies are especially useful in situations where employees are spread across different locations. For example, if a hurricane strikes New York City, your employees could still use the VPN to continue working.

Site-to-site VPNs connect two networks, such as a corporate network and a branch office network. This type of VPN utilizes your internet connection to pass private traffic, making it an excellent alternative to private MPLS circuits. Many organizations and businesses use this type of network to connect their branches.


Better performance than other types of WANs

A new type of point-to-point connectivity called a wavelength WAN can offer extremely high bandwidth. This type of network uses multiple wavelengths on the light spectrum to achieve maximum bandwidth and low latency. It is highly popular in the technology and financial sectors, and is increasingly being used by internet service providers. As a result, carriers are building new wavelength routes to keep up with demand.

The speed of a WAN depends on a variety of factors, including the type of wide area network cabling and the type of equipment that connects to it. Distance also plays a role in how fast a WAN is. For example, data transfers between two states in the U.S. are typically much faster than those between London and Los Angeles. To speed up such long distance transfers, high-quality copper submarine cables are commonly used.

Another advantage of SD-WAN is that it has the potential to integrate multiple types of connections. It uses multiple tunnels to maximize WAN bandwidth. This gives it a distinct advantage over traditional IPsec VPNs. It also ensures that applications enjoy the highest QoS possible, which is vital for ensuring optimal performance. This technology can also help improve network redundancy and simplify network management.

Another benefit of SD-WANs is that they have an inbuilt feature called WAN Optimisation (WAN-OP). WAN-OP helps reduce latency, a major factor in improving throughput. Even 20ms of latency can cut throughput by 80% or more. Latency mitigation strategies such as moving the end points closer to one another can reduce latency dramatically.

Despite the growing popularity of the cloud, bandwidth requirements continue to increase. Legacy WAN architectures backhaul data to a data center, which is inefficient and costly. While SD-WAN offers a low-cost solution while allowing users to benefit from high-quality networking services.
