Virtual Desktop Infrastructure (VDI) relies on a client-server model where display remoting, input handling, and peripheral redirection occur over network protocols. Citrix has dominated this space with its HDX (High Definition Experience) protocol. The Citrix VDI Plugin—often delivered as part of Citrix Workspace app (formerly Receiver)—is the software agent installed on end-user devices (Windows, macOS, Linux, Chrome OS, iOS, Android). It interprets ICA (Independent Computing Architecture) traffic, renders the remote desktop locally, and redirects local resources (drives, printers, USB devices, clipboards) securely. renders the remote desktop locally
