DEVICE AND METHOD FOR AUTOMATIC SELECTION OF COMMUNICATION PROTOCOL OF NETWORK

PROBLEM TO BE SOLVED: To automatically select the best communication protocol in environment wherein computers are connected to a network without paying attention to applications. SOLUTION: The network 70 is constituted by connecting the computers 10a and 10b which have communication protocols 1-3 with characteristics of different network loads, CPU loads, and reliability and a load monitor device 60 which monitors the load on the network. In this case, each computer has various tables such as a CPU load monitor table 32a for monitoring the CPU load of the computer and a network load monitor table 31a for monitoring the network load from the load monitor device and is equipped with an automatic protocol selecting device 30a which selects the best communication protocol under selection conditions of a user-settable selection condition table 36a according to load information from those tables. Consequently, there is no need to pay attention to applications and even when computers in the network increase in number, network load problems are prevented.
