Router Frame Relay Network Access Software Design And Implementation

This paper includes two parts on technology and realization of frame relay network. One is about technology and protocol of frame relay, the another design and realization of access software in frame relay network.Contents of this paper mainly include reseach of frame relay technology, architecture of frame relay, design and realization of access software in frame relay network. Deep discussions are offered for design and realization of several key technology, such as serial communications BSP design and realization, frame relay protocol design and realization, design and realization of interface between VxWorks RTOS and char & network devices, and PowerPC860's communications processor module.The data and contents of this paper come from my two years of reseach experiences.
