Abstract: A packet processing method includes: a traffic classifier receives a first packet; the traffic classifier determines, in policy information in the traffic classifier and according to a first filtering rule that matches the first packet, a first service identifier that matches the first filtering rule, and an address, which matches the first filtering rule, of a first service routing trigger. The traffic classifier sends a second packet to the first service routing trigger. Where the policy information includes: a filtering rule, an address of a service routing trigger, and a service identifier corresponding to the filtering rule. Where the filtering rule is used to identify a packet, and the service identifier is used to represent a sequence of a service node that processes the packet. Where the second packet is formed by adding the first service identifier to the first packet.

Abstract: The application disclose a packet processing method that includes: receiving, by a service distribution node, service routing information sent by a controller, where the service routing information includes a flow identifier, a service identifier, and a next-hop address, the flow identifier is used to identify a packet flow, the service identifier is used to identify a sequence of a service node instance that processes the packet flow, and the next-hop address is used to identify the service node instance that processes the packet flow; receiving a first packet; acquiring a first flow identifier according to the first packet, and searching the service routing information according to the first flow identifier to acquire a matched service identifier and a matched next-hop address; and sending a second packet to a first service node instance that has the matched next-hop address, which implements service processing on a packet flow.

Abstract: Embodiments of the present invention provide a method, a device, and a system for controlling a network path, where the method includes: the first control device generates path information for a first AP according to network topology information, and generates first forwarding information for the first AP according to acquired forwarding resource information of the first AP and the path information, and sends the first forwarding information to the first AP; the first control device determines that a second AP which is not managed by the first control device is included in the path information, sends the path information to a second control device for managing the second AP, so that the second control device generates second forwarding information for the second AP according to the path information and the acquired forwarding resource information of the second AP, and sends the second forwarding information to the second AP.
