Method for transferring a user interface from at least one server via a proxy to at least one client, wherein a user interface of the server is transferred to the client such that the user interface is displayed on the client, and the server can be controlled from the client, wherein in order to display the user interface on the client, a data stream of a plurality of successive frames is transmitted from the server to the client by means of a packet-based transfer, wherein a latency (AFL, IFL) of the transfer is determined recurrently for individual frames in order to monitor the transfer, wherein the method comprises at least one of the following steps: (i) wherein the latency is determined as the absolute frame latency, namely as the difference between a start of a server-side processing of a particular frame, and the end of a client-side processing of that particular frame, the user interface of the server is transferred via the proxy to a plurality of clients, resulting in a dedicated data stream for each client, each client determines the absolute frame latency for the associated data stream, and the proxy determines the largest absolute frame latency, which it transmits to the server, (ii) wherein the frames from the server are forwarded by the proxy at a frame rate that is adapted dynamically by ascertaining a round-trip time between the server and the client, and depending on the round-trip time, forwarding only a subset of frames to the client, the subset of frames that is forwarded is defined by an adjustable factor, which specifies a number of successive frames, of which one is forwarded and all the others are discarded, the factor is increased by 1 if the round-trip time exceeds an upper threshold value, and decreased by 1 if the round-trip time goes below a lower threshold value. wherein a user interface of the server is transferred to the client such that the user interface is displayed on the client, and the server can be controlled from the client, wherein in order to display the user interface on the client, a data stream of a plurality of successive frames is transmitted from the server to the client by means of a packet-based transfer, wherein a latency (AFL, IFL) of the transfer is determined recurrently for individual frames in order to monitor the transfer, wherein the method comprises at least one of the following steps: (i) wherein the latency is determined as the absolute frame latency, namely as the difference between a start of a server-side processing of a particular frame, and the end of a client-side processing of that particular frame, the user interface of the server is transferred via the proxy to a plurality of clients, resulting in a dedicated data stream for each client, each client determines the absolute frame latency for the associated data stream, and the proxy determines the largest absolute frame latency, which it transmits to the server, (ii) wherein the frames from the server are forwarded by the proxy at a frame rate that is adapted dynamically by ascertaining a round-trip time between the server and the client, and depending on the round-trip time, forwarding only a subset of frames to the client, the subset of frames that is forwarded is defined by an adjustable factor, which specifies a number of successive frames, of which one is forwarded and all the others are discarded, the factor is increased by 1 if the round-trip time exceeds an upper threshold value, and decreased by 1 if the round-trip time goes below a lower threshold value.
