Link concept

A link is a channel for communication between sites. Links serve as a transport for application connections and requests. A set of linked sites constitutes a network.

To create a link to a remote site, the remote site must provide link access. A link access is an external access point for accepting links.

Application connections and requests flow across links in both directions. A linked site can communicate with any other site in the network of sites, even if it is not linked directly.

Links are encrypted and authenticated using mutual TLS. You can use access tokens to create links.
