Full-Mesh WAN is a networking topology in which all nodes or sites are interconnected with direct links to each other, forming a complete mesh or network. In a Full-Mesh WAN, each site has a direct connection to every other site, allowing for direct communication between any two sites in the network.

This topology is commonly used in Wide Area Networks (WANs) where multiple geographically distributed sites need to be interconnected. In a Full-Mesh WAN, the advantage is that it provides maximum redundancy and fault tolerance. Since each site has a direct link to every other site, if one link or site fails, the remaining sites can still communicate directly with each other.

The number of connections in a Full-Mesh WAN can be calculated using the formula n(n-1)/2, where n is the number of sites. As the number of sites increases, the number of connections grows exponentially. Therefore, implementing a Full-Mesh WAN can become costly and complex as the number of sites increases.

Despite its advantages, Full-Mesh WANs have some disadvantages. The cost of implementing and maintaining the direct connections between all sites can be high. Additionally, the complexity of managing and troubleshooting the network may also increase with the number of sites. Therefore, Full-Mesh WANs are typically used in scenarios where high availability and direct communication between sites are critical, such as financial institutions or government agencies.
