NODE APPARATUS FOR CLOCK SYNCHRONIZATION IN RESIDENTIAL ETHERNET SYSTEM AND METHOD FOR CLOCK SYNCHRONIZATION

摘要

1. The art that the invention defined in the claims ; The present invention relates to a cash register deonsyeol Ethernet, shall in particular, to an apparatus and method for maintaining synchronization with the clock, even if multiple devices are connected to that node. ; 2. In the aspect ; This invention is a basic clock based on the time synchronization method in the register deonsyeol Ethernet system to be Solved by the invention, the hop synchronization complete message at the top if a large number of switch hops are present The aim is that to provide a node device, and a clock synchronization method for clock synchronization in the synchronization register deonsyeol Ethernet reducing errors that may occur when there is a large number of hop by performing a synchronization process, and then delivered to. ; 3. A base ; The solution to the present invention invention is a node device for clock synchronization in the register deonsyeol Ethernet system, the clock information by receiving the clock synchronization information and end information transmitted from the superordinate device delivering the local clock and the slave port to forward to the master port of the node device inside the synchronization termination information; Receiving the clock information from the slave port, the local clock to change the internal clock of the node apparatus; And by receiving the synchronization message from the slave port on the end, including at least one port for transmitting the master clock from the local clock as a child of the node device. ; 4. An important use ; The present invention used to fight like Reggie deonsyeol Ethernet invention.
