Abstract
A method includes receiving, by a first node on a first port of the first node, a first packet from a second node; and when the first packet carries a first flag, avoid selecting, by the first node and when selecting a clock source, a clock source corresponding to the first port, where the first flag indicates that time synchronization of the second node is uncertain.
Claims20
A method for selecting a first clock source implemented by a first node, wherein the method comprises:
- receiving, on a first port of the first node, a first packet from a second node, wherein the first packet is a first announce packet, and wherein the first packet carries a first flag indicates that a time synchronization of the second node is uncertain;
- and
- avoiding selecting, in response to the first packet carrying the first flag, a second clock source corresponding to the first port when selecting a first clock source, wherein the first clock source is a clock source of the first node.
A first node comprising:
- a first port;
- one or more processors;
- and
- one or more memories configured to store instructions, wherein when executed by the one or more processors, the instructions cause the first node to:
- receive, on the first port, a first packet from a second node, wherein the first packet is a first announce packet and wherein the first packet carries a first flag indicates that a time synchronization of the second node is uncertain;
- and
- avoid selecting, in response to the first packet carrying the first flag, a second clock source corresponding to the first port when selecting a first clock resource, wherein the first clock source is a clock source of the first node.

A system for selecting a first clock source, comprising:
- a second node configured to send a first packet, wherein the first packet is a first announce packet;
- and
- a first node coupled to the second node and configured to:
- receive, on a first port of the first node, the first packet from the second node, wherein the first packet carries a first flag indicating that a time synchronization of the second node is uncertain;
- and
- avoid selecting, in response to the first packet carrying the first flag, a second clock source corresponding to the first port when selecting a first clock source, wherein the first clock source is a clock source of the first node.
