Service management method and connection oriented network system using such management method

摘要

For a connection-oriented network system in which information terminals such as PC and WS are connected to a network such as LAN and WAN and a logical connection is established if necessary to a terminal to transfer data over the established connection, a service management method is provided which allows data transfer without connection management by a service application. A communication driver for data transfer is provided with a connection processing unit for establishing a connection to a transmission destination terminal and a connection queue for temporarily storing transmission data during a connection process. If a connection is still not established between terminals for data transmission, the connection processing unit stores the transmission data supplied from a service application in the connection queue, establishes a connection to the transmission destination terminal designated by the service application, and thereafter dequeues the transmission data from the connection queue to transmit the transmission data over the established connection.
