Efficient Scheduling Telecommunications Method Using First Cyclic Ethernet Protocol and Second Cyclic Ethernet Protocol

摘要

The present invention relates to a method of transmitting data by hop between communication entities. The communication entity is at least one master entity (M) configured to communicate according to the first protocol, and a first of the slave entities capable of supporting communication according to the first protocol and not supporting communication according to the second protocol. A plurality of slave entities including a group and a second group (NGS) of slave entities capable of supporting communication according to the second protocol is provided. The first protocol is executed until the token reaches the master entity again by token passing by communication data from the master entity to each neighboring slave entity in succession, and thus defines the first cycle according to the first protocol. . The second protocol is implemented by passing a data frame containing the intended data to the second group of entities, and one current entity in the second group, upon receiving the data frame, the current entity Change the data frame by acquiring the data intended for the data frame and / or by adding the data intended for other entities in the second group to the data frame, and the data frame thus changed, It is configured to continuously transmit a data frame to the neighboring entity until it reaches the current entity, and thus define a second cycle according to the second protocol.
