Abstract: Example packet processing methods and devices are described. One example method includes that a first device identifies a received first packet through a first FlexE shim layer disposed in the first device. When identifying that the first packet is a flexible Ethernet (FlexE) packet, the first device performs timeslot mapping on the first packet, then encapsulates the first packet into a first gigabit passive optical network encapsulation mode (GEM) frame. One first identifier is selected by the first device from at least one identifier reserved for a FlexE service, and is allocated to the first GEM frame, where the first identifier is used to indicate that the first GEM frame is a GEM frame corresponding to the FlexE packet. The first device sends the first GEM frame that carries the first identifier.

Abstract: Embodiments of the present invention provide a load sharing method and apparatus, and a board. The method includes: receiving, by a built-in forwarding unit, to-be-transmitted data; obtaining, by a management control unit, current load ratios of forwarding units; and if it is determined that a current load ratio of any forwarding unit of the forwarding units is less than a preset load ratio threshold, determining that the forwarding unit is a unit for forwarding the to-be-transmitted data, where the built-in forwarding unit and the management control unit are located in a same board, and the forwarding units include the built-in forwarding unit and another forwarding unit outside the board. The present invention can solve a problem of low data transmission reliability in an existing load sharing method.

Abstract: An optical network unit (ONU) receives an Ethernet packet sent by user device and slices the Ethernet packet based on information about a minimum transmission unit to generate a first Ethernet packet slice, where a length of the minimum transmission unit is an integer multiple of a length of the first Ethernet packet slice. The ONU encapsulates the Ethernet packet slice and a slice identifier into a GEM frame, wherein the slice identifier indicates that the length of the minimum transmission unit of the OTN is an integer multiple of the length of the Ethernet packet slice. The Ethernet packet slice does not need to be processed by a network processor or a traffic management module in transmission of the OLT, thereby reducing a delay of network transmission.

Abstract: The present disclosure relates to an optical access device and an optical access system. The system includes a switching unit, at least two optical access devices, a network integrated processor, and a controller. The optical access device decapsulates an upstream data frame to obtain a payload, encapsulates the payload into a first upstream Ethernet frame, and then sends the first upstream Ethernet frame to the switching unit. The switching unit, which may comprise at least one switch, is configured to send the first upstream Ethernet frame to the network integrated processor, or send the first upstream Ethernet frame to the controller, and receive and send a second upstream Ethernet frame. The network integrated processor processes the first upstream Ethernet frame according to a received protocol parse instruction to obtain the second upstream Ethernet frame, and sends the second upstream Ethernet frame to the switching unit.
