API Development for Persistent Data Sessions Support

摘要

This thesis studies and discusses the development or the APT, called the persistency APT, for supporting the persistent data sessions. Without persistent session support, network applications often need to he restarted from the beginning hen intermittent physical connection Toss happens. Application programmers tan use the persistency APT to achieve the service continuity. The persistency APT provides the interface that allows a program to continue retrieve data from the Point the connection is lost after the Physical connection is restored. The rots or this thesis is to develop a generative Persistency APT that supports various types of applications. This thesis studies the Persistent session support for two types of transport protocols, TCP and UDP, which are used by major or network applications . An application that performs test file and file transfer is implemented to demonstrate the persistent data transfer sessions for TCP and UDP, respectively. The study shows that the proposed APTs can support the data transfer continuity in the reconnection process.
