Abstract: A packet header information obtaining method. The method includes: obtaining, by a communications device, a first packet, where the first packet includes a plurality of extension packet headers; and obtaining an extension header self-describing option from the first packet, where the extension header self-describing option is used to indicate information about the plurality of extension packet headers. Therefore, the communications device obtains, based on the extension header self-describing option in the first packet, a first extension packet header included in the plurality of extension packet headers. Packet header information of the extension packet header in the first packet can be obtained by using the extension header self-describing option, and the first extension packet header that needs to be parsed can be directly located from the first packet by using the obtained packet header information.

Abstract: A method for providing a service for a traffic flow includes a network device receives a first packet; and when a packet feature of the first packet matches a packet feature of the traffic flow, the network device encapsulates an indication identifier of the traffic flow into the first packet to obtain a second packet, and sends the second packet. The second packet is an Internet Protocol (IP) version 6 (IPv6) packet or a Multiprotocol Label Switching MPLS packet. The indication identifier indicates the service provided for the traffic flow.

Abstract: A transport network slice subset management entity is configured to provide an NSSMF (Network Slice Subset Management Function) of a TN (Transport Network), wherein the transport network slice subset management entity is configured to receive from or send messages to a network slice management entity and to provide configuration information to entities of a transport network. A method for interfacing with a transport network slice subset management entity, comprises the steps receiving, from a request originator, a message comprising a request relating to a network slice subset instance, updating a network slice database of a transport network, according to said request and configuring an entity of a transport network according to said request. A network slice management entity configured to provide an NSMF (Network Slice Management Function) is configured to send messages to or receive messages from a transport network slice subset management entity.
