Patent ID: 8644195

Claim:
A ring-based network, comprising: a plurality of nodes each having two ring ports and an unrepeated priority value, and each ring port being in a blocked status at an initial status, and each node outputting a first link-up packet, and each first link-up packet including the priority value of each node; and a plurality of links coupled to the ring ports respectively; wherein, in the initial status, each node compares each first link-up packet, and fills the priority value of each node into the first link-up packet having a higher priority value to form a second link-up packet, and the priority value of each node and the highest priority value of each adjacent node recorded by each node are compared with each second link-up packet, and if the priority value of the node and the highest priority value of each adjacent node recorded by the node are smaller than the second link-up packet, the ring port enters into a forward status, and the links form a plurality of forward links and a blocked link respectively according to the forward status or the blocked status of each ring port.
