Abstract
A remote mobile device periodically connects with a centralized data server to receive updated information. Because of the mobile nature of the remote device, a download of all available information may not be able to be completed during the initial network connection. When the mobile device can again reconnect to the centralized data server, the two machines are able to continue the exchange of information even if the new network connection uses different underlying technologies or different connection protocols. A fragmentation layer is used in the protocol stack above the transport layer to separate messages into chunks. By tracking which chunks are successfully sent between the two machines, the efficient exchange of messages can occur across multiple, different network connections.
