Abstract: 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.

Abstract: The present invention provides an access method and system of a customer premise equipment, and a broadband network gateway. The access method of a customer premise equipment includes: receiving, by a BNG in a BNG pool, an access request packet sent by a CPE, where the access request packet carries an identifier of a CPE group to which the CPE belongs; and obtaining, by the BNG, an access policy of the CPE group according to the identifier of the CPE group, and performing access control on the CPE according to the access policy. Through the present invention, a BNG in a BNG pool is enabled to provide an access service for a CPE according to an access policy, so that when a BNG in a BNG pool is faulty, a BNG that is not faulty in the BNG pool can provide an access service for a CPE originally accessing the faulty BNG, thereby improving the reliability of the entire network.

Abstract: A troubleshooting method, a device, and a readable storage medium are provided, to detect a unidirectional fault in a ring Ethernet and provide a fault recovery mechanism after the unidirectional fault occurs. In embodiments of this application, if determining that a link corresponding to a receiving unit of a first port is in a fault status, the first device performs loopback on the first port, and sends a first continuity check message to a second device via the first port. The first continuity check message carries first indication information. The first indication information indicates that a link corresponding to a receiving unit of a port that sends the first indication information is in a fault status.

Abstract: The present subject matter relates to the field of communications technologies, and in particular, to a method and an apparatus for indicating a fault in flexible Ethernet. The method for indicating a fault includes: detecting whether a fault occurs in at least one physical layer entity included in a flexible Ethernet group; and when a fault occurs in the at least one physical layer entity, periodically sending a fault indication code block to a flexible Ethernet client corresponding to the at least one physical layer entity in which the fault occurs. Not all bandwidth of a downstream transmission path in the flexible Ethernet is occupied, and data transmission on a non-faulty channel in a same flexible Ethernet group is not affected, thereby reducing a quantity of affected flexible Ethernet clients.

Abstract: The present application discloses a method for generating forwarding information. The method includes: determining, by a controller, a first SFE and a second SFE that are used to forward a service stream, where the first SFE and the second SFE are on a service function chain corresponding to the service stream; generating, by the controller, first forwarding information for the first SFE and generating second forwarding information for the second SFE; and sending, by the controller, the first forwarding information to the first SFE and sending the second forwarding information to the second SFE. According to the method for generating forwarding information, the controller generates forwarding information for the SFE, so that a service chaining technology can be applied to a service environment in which a large quantity of services and a large quantity of service processing function units exist.
