Abstract
One embodiment of the present invention provides a system that supports low-latency session-mobility for an ultra-thin-client. During system operation, an ultra-thin-client sends a location-identifier to a Connection Assignment Server (CAS), which facilitates communication with a user-interface (UI) server, wherein the location-identifier specifies the current location of the ultra-thin-client. Next, the ultra-thin-client receives the address of a local UI-server from the CAS, wherein the CAS selects the local UI-server based on the location-identifier. The ultra-thin-client then sends a user-session identifier to the local UI-server. This allows the local UI-server to retrieve a user-session-image for a user-session from a user-session-image repository. Note that, before moving to the current location, the ultra-thin-client was previously communicating with a remote UI-server, which stored the user-session-image in the user-session-image repository. Next, the ultra-thin-client establishes a user-session connection with the local UI-server. In this way, the system enables the ultra-thin-client to resume the user-session through the local UI-server. Note that the system reduces the delay experienced by the user because it enables the ultra-thin-client to carry on the user-session with the local UI-server instead of the remote UI-server.
