摘要： A clock synchronization system synchronizes a clock of a slave node with a clock of a master node. The master node includes a packet transmitting unit that transmits a packet including a time stamp (TS) to the slave node. The slave node includes: a packet receiving unit that receives the packet transmitted from the master node; a packet filter unit that calculates as a value of delay of the packet a difference between a TS on the clock of the slave node when the packet is received and the TS of the packet received, corrects the value of the delay of the packet or a threthold for the delay of the packet, and performs filter processing on the packet received from the packet receiving unit based on the value of the delay of the packet and the threshold for the delay of the packet; and a phase synchronization unit that outputs the clock of the slave node based on the TS included in the packet employed.

摘要： Two transmission devices connected to a link in which a failure occurs turn back a ring. Other transmission device changes a transmission ring of an NNI packet which is a UNI packet whose transmission source is its own transmission device and which had been transmitted through the link before the failure occurs to have a reverse direction. In addition, each transmission device, upon receiving an NNI packet whose transmission destination NNI address is one or any one of a plurality of NNI addresses applied to its own transmission device, outputs the packet to a self-owned tributary port irrespectively of whether it is sent through an inner ring or an outer ring.
