DATA COMMUNICATION SYSTEM AND METHOD OF ESTABLISHING COMMUNICATION PATH

摘要

PURPOSE: To enable a host to execute normal control for host application or a terminal user by defining a local SNA(system network architexture) network in each SNA host by a front end processor connected to a channel. CONSTITUTION: A function between an SNA terminal and an SNA host can connect remote products such as a cluster controller 3274 and relative terminals such as 3273, 3180 and attain the direct connection of a PC for emuting a device 3270. A centralized network control function attains a centralized control communication network manager by using IBM network control program products such as a network communication control function, a network direct control function and a network problem discrimination application. An inter-host function attains a communication function, mutually addresses MVS and VM host systems and executes communication beween these host systems through a DDN.
