摘要： A method, computer program product, and computer system for client-server communication based on delta transfer. A server of the computer system receives from a client a HTTP request for transferring a current image page, compares the current image page and a saved image page which is stored on the server for the client. Based on the comparison, the server of the computer system constructs delta contents between the current image page and the saved image page. The server of the computer system updates the saved image page on the server with the current image page and sends a HTTP response comprising the delta contents to the client.

摘要： A plurality of network addresses identify a source device in the network. A plurality of subscriptions for the source device to receive messages from the target devices each identify one of the target devices and one of the source network addresses the identified target device uses to communicate with the source device. Upon detecting a change to a changed network address, a determination is made of a subscription indicating the changed network address and the target device indicated in the determined subscription is determined. A selection is made of a selected network address, other than the changed network address is selected. If the selected network address can be used to communicate between the determined target device and the source device, then the selected network address is used and provided to the determined target device.
