A microcomputer network is designed and implemented for a resource sharing and mail service in a small organization. It is a centrally controlled multidrop type, which connects many CP/M-based slave computers with a MP/M-based master computer.
The overall structure and functions are discussed first. The high-level protocols of transport and session layers and their interfaces are designed and implemented to implement the CP/NET functions. Also a reliable mail service function is implemented.
The performance of the transport service of the network is partially tested and discussed.
