Remote Adapters can communicate with the Proxy Adapters deployed inside the Lightstreamer Server, via TCP sockets, through the ARI protocol.
This SDK provides the full specifications of the ARI protocol.
The other Adapter SDKs (except for Java In-Process Adapter SDK) implement this protocol through different languages.
Refer to the "Adapter Remoting Infrastructure" included in Lightstreamer Server package for an overview of the general architecture and deploy instructions for the Proxy Adapters.
