TCP/IP-based client interface to network information distribution system servers

摘要

A TCP/IP-based client-server interface for sending service requests from a client computer to a Network Information Distribution Services server. The TCP/IP-based client-server interface is an easily implemented and economical alternative to the proprietary UDP/IP-based client-server interface developed for communication between client computers and Network Information Distribution Services servers. A service request is sent to a specific TCP/IP logical port associated with a particular type of service. A process associated with the specific TCP/IP logical port formats the request in the same manner as requests received through the proprietary UDP/IP-based client-server interface are formatted, and then directs the formatted requests to the Network Information Distribution Services server process that executes the requests.
