The present invention relates to the communications field, and discloses a packet processing method, an apparatus, and a system, so that context processing can be separately performed on a packet by using distributed forwarding-plane devices, so as to improve load balance during the context processing of the network packet. The method includes: receiving, by an ingress network element, a flow entry sent by a control network element; receiving, by the ingress network element, a packet; performing, by the ingress network element, matching on the packet according to the flow entry, and acquiring a packet on which context processing is performed this time; forwarding, by the ingress network element, the packet to a processing network element, so that the processing network element performs context processing on the packet, or forwards the packet to a processing network element for context processing after performing context processing on the user. Embodiments of the present invention are applied to context processing of a packet.

Embodiments of the present invention provide a QoS control method and a device for SDN. A control plane device includes: a determining unit, configured to determine a flow entry, where the flow entry includes QoS information, the QoS information is used to indicate a QoS processing rule, the QoS processing rule includes a QoS parameter, and the QoS processing rule is used to instruct to perform QoS control on a data packet according to the QoS parameter; and a sending unit, configured to send the flow entry to a forwarding plane device, so that the forwarding plane device obtains the QoS processing rule, and performs QoS control on a target packet according to the QoS parameter in the QoS processing rule, where the target packet is a data packet that matches the flow entry. In the embodiments of the present invention, because the QoS information included in the flow entry is used to indicate the QoS processing rule, the forwarding plane device can perform QoS control on the target packet according to the QoS processing rule, so that a QoS control function in the SDN can be implemented.

Embodiments of the present invention provide a method for processing a packet in a software-defined network (Software-Defined Network), where the method is performed by a forwarder, and the method includes: receiving an input packet; determining a flow to which the input packet belongs according to the input packet; determining a context identifier set corresponding to the flow to which the input packet belongs according to a first correspondence between flows and context identifier sets, where a context identifier set corresponding to each flow in the first correspondence includes at least one context identifier; determining a context corresponding to the context identifier set according to a second correspondence between context identifiers and contexts; and processing the input packet according to the context corresponding to the context identifier set. In the embodiments of the present invention, a flow is not directly associated with a context, and even when multiple flows share a context, this context does not need to be saved for multiple times, and under a hardware condition the same as that in the conventional technology, a storage capability and a processing capability of a forwarder are greatly improved in the embodiments of the present invention.

The present invention discloses a method and a system for sharing a deep packet inspection parsing result, and a corresponding equipment. The method includes the following steps: a serving network element receives a user packet; performs deep packet inspection on the user packet, to obtain a deep packet inspection parsing result; and sends, to a forwarding network element which sends a request, the deep packet inspection parsing result, to achieve sharing of the deep packet inspection parsing result. A serving network element is provided in the operational network to perform the deep packet inspection on the user packet, and in a case that a forwarding network element sends a request to the serving network element, a deep packet inspection parsing result is sent to the forwarding network element which sends the request, to achieve sharing of the deep packet inspection parsing result, thereby the occupied computing resources of the forwarding network element is reduced and the packet forwarding efficiency of the forwarding network element is improved.
