Research in a Framework of Embedded Network Protocol Stack and Application

This paper introduces a network stackpsilas framework based on embedded systems. In order to improve the portability of the stack, this paper puts forward the system abstraction layer. For the maintainability, the multi-connection management of the stack and the access control, connection layer is introduced. Communication interface layer enhances the transaction way between the stack and the application. In order to compatible with the BSD socket API to make network applications applied directly in the embedded protocol stack framework, this paper designs and implements the Socket Lib.
