- This paper studies how to avoid timing loop in the self-healing ring (SHR) network with synchronous digital hierarchy (SDH) and analyzes the generation and mechanism of timing loop in SDH local ring network as well as the harmfulness of timing loop to the network. Based on these results, a new method is proposed to avoid the generation of timing loop in the multiplex section protection ring by combining the K1 and K2 bytes in APS protocol of the multiplex section with S1 byte in the synchronization status message (SSM). This method improves the synchronization performance of SDH SHR network.
