碩士 === 國立成功大學 === 電腦與通信工程研究所 === 95 === This thesis presents the implementation of a network module in a microkernel operating system. The goal of this thesis is to provide the microkernel operating system the capability of communicating with other nodes on Internet through TCP/IP network protocols. The implementation includes a network module which consists of a network manager and TCP/IP network protocols, and a socket library. The network module designed and implemented in this thesis is independent of other modules in the microkernel operating system architecture. It operates with applications and the microkernel through message passing. It supports five popular TCP/IP network protocols namely IP, ARP, ICMP, UDP, and TCP. The implementation of the socket function library consists of 17 popular socket functions which can be used in developing network related application programs. From the testing for the functional correction and performance, satisfactory results are observed. The functionality of network communication is becoming indispensable for modern embedded system products especially in comsumer electronics market. This implementation attempts to achive an efficient and reliable network module in a microkernel operating system. The network module is separated from the microkernel and other modules in the system. Its code size of 105K bytes is relative small. It can be ported to other platform without much effort. Therefore, this implementation provides another choice for developing network software in embedded systems.
