The application discloses a communication
system, a communication method, a
communication device, a
chip and an electronic device. The communication
system comprises a plurality of nodes, each node having a sending port and a receiving port, and each node is sequentially connected with the receiving port of an adjacent node through the sending port, forming a unidirectional ring path. In a self-generation mode, a node sends a data frame generated by itself to a next node, and the hop count of the data frame generated by itself is an initial value. In a
relay mode, the node judges a hop count field in a received data frame. If the hop count does not reach a threshold value, the hop count of the data frame is incremented and then forwarded to a next node. If the hop count reaches the threshold value, the forwarding of the data frame is stopped. Through the unidirectional ring
data path, full-duplex self-synchronization is realized. Each node autonomously decides to forward by checking whether the hop count in the data frame reaches the threshold value, without the need for central scheduling and address allocation, thereby improving the flexibility and stability of
system expansion.
