Abstract: A packet forwarding method, apparatus, and system, and a computer-readable storage medium are disclosed, and pertain to the field of communication technologies. After receiving a packet sent by a second device, a first device determines a target service node based on indication information and an application service identifier that are in the packet, where a service capability of the target service node matches the indication information, and a target application service corresponding to the application service identifier is deployed in the target service node. Then, the first device sends the packet to the target service node. The indication information is carried in the packet sent by the device, so that a forwarding device can send the packet to a service node whose service capability matches the indication information. In this way, differentiated application services are provided for devices of different levels, and flexibility of task scheduling is high.

Abstract: This application discloses a method for computing a forwarding path. The method includes: receiving, by a network device, notification packets separately sent by a plurality of forwarding nodes, where each notification packet includes interface forwarding delay information of the forwarding node that sends the notification packet, device forwarding delay information of the forwarding node, and a transmission delay of a link connected to the forwarding node; obtaining the interface forwarding delay information and the device forwarding delay information of each of the plurality of forwarding nodes, and obtaining a transmission delay of a link between the plurality of forwarding nodes; and computing a forwarding path between a first forwarding node and a second forwarding node, where a forwarding delay of the forwarding path meets a delay requirement of a service.

Abstract: This application discloses a packet forwarding method, an apparatus, and a system, and belongs to the field of communication technologies. The method includes: A first node receives a first packet. The first node sends a second packet to a second node based on the first packet, where a source address of the second packet is obtained by translating a source address of the first packet, a destination address of the second packet is a destination address of the first packet, a packet payload of the second packet is a packet payload of the first packet, the second packet further includes a session identifier, and the session identifier is used by the second node to forward the second packet.

Abstract: A packet forwarding method. In this method, a forwarding node receives a packet, obtains a target service resource status advertised by each service node in a plurality of service nodes, selects a target service node from the plurality of service nodes based on the target service resource status advertised by the service node, and forwards the packet to the target service node. In other words, the forwarding node can sense a service resource status advertised by the service node, and the service resource status can indicate a resource usage status of a service resource managed by the service node. An actual processing capability of the service node can be sensed based on the resource usage status.

Abstract: An SFC-based communications method and system, and an apparatus are provided. The SFC includes a CF node, an SFF node, and an SF node, and the SFF node is connected to the SF node. The method includes: receiving, by the CF node, a first message from the SFF node; obtaining, by the CF node, network topology information of the SFC based on the first message; obtaining, by the CF node, an SFC forwarding table, where the SFC forwarding table is determined based on the network topology information of the SFC; and sending, by the CF node to the SFF node, a second message used to indicate the SFC forwarding table. In this way, a network topology of the SFC can be flexibly and efficiently discovered.
