/ Method for enhancing Token passing/polling method

摘要

In the present invention, token passing/polling schedule control in a network system in which at least one assertion value acquires data transmission rights through the token method, and a plurality of sub-devices dependent on the main device acquires data transmission rights through the polling method of the main device. A method comprising: detecting a token reception period of a primary device; Detecting a polling reception period of the auxiliary device; Setting a minimum common multiple value of token circulation period values of each main device as a token management factor (T) from the number of token circulations in which the token circulation is repeated; And setting the polling period of the sub-device as the main device token receiving period (P) * the polling receiving period (Q) of the sub-device.
