A service packet processing method, apparatus, and system, the method including receiving, by a first network device, a first packet, where the first packet includes a first service path identifier, and the first service path identifier indicates a first service path for transmitting the first packet, generating, by the first network device, a second packet based on the first packet, where the second packet includes a second service path identifier indicating a second service path, and the second service path identifier is different from the first service path identifier, and sending, by the first network device, the second packet via the second service path.

Service packet processing method, apparatus, and system

An embodiment method includes: a first service atom receives a second packet sent by a central switching device, where a first service packet is encapsulated in the second packet and the second packet further includes a first service path identifier. The first service atom performs first service processing according to information in the first service packet, to obtain a first processing result. The first service atom queries a first path switching entry according to the first processing result and the first service path identifier. The first service atom sends a third packet to the central switching device, where a source device identifier of the third packet is a device identifier of the first service atom, a second service packet is encapsulated in the third packet, and the third packet includes the second service path identifier.

A method for determining a clock synchronization path, and a device, where the method includes determining a first clock synchronization path from a clock injection node of the first network to the first network element based on a request of the first network element and the clock synchronization topology of the first network. A clock synchronization topology is automatically updated based on clock synchronization capability information of a network element, and a clock synchronization path is determined to reduce costs of deploying a clock synchronization path.

Method for updating clock synchronization topology, method for determining clock synchronization path, and device

A method, node, and system for detecting a clock synchronization path, where the method includes generating, by a first node, a synchronization detection request message, sending the synchronization detection request message to a second node, where the synchronization detection request message includes an identifier (ID) of the first node, generating, by the second node, a synchronization detection response message according to the synchronization detection request message, sending the synchronization detection response message to the first node, where the synchronization detection response message includes clock topology information of the second node and the ID of the first node, and obtaining, by the first node, a first detection result according to the synchronization detection response message, where the first detection result indicates a status of a clock synchronization path between the first node and the second node.
