Abstract: A method and system for simulating high-bandwidth throughput on a low-bandwidth connection in a network is disclosed. The network includes at least one server and multiple client devices, where a first client device is connected to the server via the low bandwidth connection. Once a client device logs in to network and accesses a software application running on the server, only display data are transmitted to the client device. The display data is transmitted by breaking application display data for an object into subpackets, and then encapsulating the subpackets in a TCP/IP packet. The TCP/IP packet is provided with a header indicating a total number of packets in the package and a destination address of the client device receiving the packet, such that when the TCP/IP packet is routed across the network to the client device, only the header of TCP/IP packet needs to be read.
