Clock information processing method and device

Abstract

The embodiment of the invention provides a clock information processing method and device. The clock information processing method comprises the steps that the current equipment receives at least one clock information from upstream equipment; the clock information comprises a grade identification, a modification identification and a path cost identification; when the grade identifications of the received clock information are the same, the current equipment selects the clock information with the minimum path cost identification as target clock information; the target clock information is adopted to calibrate a local clock; the path cost identification, the modification identification and the grade identification in the target clock information are updated; and the updated target clock information is sent to downstream equipment. With the adoption of the technical scheme, the clock information from an optimal path can be selected to serve as the target information to calibrate the local clock on the condition that the original network topological structure and the transport protocols are not changed, so that the current equipment actually selects the clock information with high clock quality to calibrate the local clock.

Description

technical field [0001] Embodiments of the present invention relate to communication technology, and in particular to a clock information processing method and device. Background technique [0002] With the rapid development of communication technology, all-IP (Internet Protocol network protocol) is the future development trend of mobile packet data network. In order to meet the synchronization requirements of mobile packet data network, the G.8261 synchronous Ethernet standard proposes the The concept is to solve the problem of clock synchronization among nodes in the packet data network. [0003] In order to select a clock signal from an upstream device to calibrate the local clock, currently, the clock information processing method adopted in the prior art, the current device compares the clock information sent by multiple upstream devices, if the clock information sent by one of the upstream devices contains If the grade identifier carried is higher than that carried in ...
