1. A network system, comprising:

  • at least one host processor having means for executing a communication access method and a communication processing application;

    a plurality of terminals;

    at least one network node each coupled to one of said at least one host processor;

    a switched network coupled to said terminals; and

    at least one front end processor system, connected to said host processor via said network node and connected to said plurality of terminals via said switched network, each executing the communication processing application, a process of communication processing server and the communication access method, effecting management and connection of said network node and said host processor for connecting said terminals in response to dialing from said terminals, referring to said network node registered as a name of a connecting destination for a terminal specified by the communication processing application, and changing/updating the name of the connecting destination of the specified terminal by the communication processing application, each of said at least one front end processor system includingconnection node management means for holding a node management table indicating a connecting relationship between said terminals and said network node of a corresponding host processor to be connected to each of said terminals, for managing connection of network nodes of one of said processors to which said terminal is connected when dialing is made from the terminal to said front end processor system;

    destination name reference means informing a network node name registered as the connecting destination name of the specified terminal in said node management table to the communication processing application when the communication processing application operated in said front end processor system specifies a terminal name and issues a system call of destination name reference;

    destination name changing means for updating the connecting destination name of the specified terminal in the node management table to a specified network node name when the communication processing application specifies the terminal name and the specified network node name and issues a system call of destination name change;

    connecting process effecting means for referring to the connection node management table to determine a connection network node and transmit a connection request to said node when dialing from the terminal to said front end processor system; and

    operation information fetching means for fetching operation information used by the communication processing application for changing the connecting destination name of the terminal.
