Abstract: A method and a system for exercising policy control, a policy and charging enforcement function (PCEF) are provided, which can solve the problem that no policy control can be exercised over application service flows without an application function (AF). In the method, a PCRF receives information about an application event sent by a PCEF after subscribing the application event from the PCEF; and the PCRF generates a control policy for a service flow of the application according to the information about the application event. In the present invention, the PCEF sends the obtained information about the application event to the PCRF, so that even when no AF is involved, the PCRF can still generate a control policy according to policy contexts including the information about the application event and the like.

Abstract: A service processing method, a service processing system, and a PCRF entity are disclosed to overcome this defect in the prior art: The prior art is unable to handle services discriminatively according to the policy context information when different services require the same QoS level. The method includes: receiving bearer priority information from a PCRF entity, where the bearer priority information includes: bearer priority information of a service data stream, bearer priority information of an IP-CAN session, and/or bearer priority information of an IP-CAN bearer; and handling services according to the bearer priority information. In the embodiments of the present disclosure, the policy context information is converted into bearer priority information so that the PCEF handles services according to the bearer priority information. In this way, different services that require the same QoS level are handled discriminatively according to the policy context information.

Abstract: Embodiments of the present invention provide a method for processing information, a forwarding plane device and a control plane device. The method includes: receiving a data packet, and extracting characteristic information of the data packet; searching for context information corresponding to the characteristic information of the data packet; buffering or discarding the data packet if the context information is not found; and sending an event reporting message to a gateway control plane device, wherein the event reporting message carries the characteristic information of the data packet, so that the gateway control plane device acquires the context information corresponding to the characteristic information of the data packet. In this way, the gateway forwarding plane device can acquire context information to the greatest extent under the condition that the context information is lost, thereby ensuring accurate forwarding of the data packet to the greatest extent.

Abstract: The present invention provides a packet processing method and an apparatus. The method includes: determining a to-be-installed flow entry and packet sending information; and sending, to a switch, a flow entry installation message carrying the to-be-installed flow entry and the packet sending information, so that the switch obtains the to-be-installed flow entry and the packet sending information from the flow entry installation message, installs the flow entry, and sends a packet according to the packet sending information. In the present invention, a controller sends a flow entry installation message carrying a to-be-installed flow entry and a packet sending message, where the to-be-installed flow entry and a to-be-sent packet are simultaneously sent, so that a switch simultaneously receives the to-be-installed flow entry and the to-be-sent packet, and performs flow entry installation and packet sending, thereby reducing unnecessary signaling exchange, and improving efficiency of flow entry installation and packet sending.

Abstract: Embodiments of the present invention provide a switch, a controller, a system, and a link quality detection method, and pertain to the field of network technologies. In the present invention, the controller determines a detection path, and controls each switch on the detection path to obtain a detection packet, so that after determining that the obtained detection packet matches a prestored flow table entry, each switch adds OAM information to the successfully matched detection packet; and the controller obtains a termination detection packet, and determines link quality according to the termination detection packet. Each switch on a detection path does not need to use a corresponding link quality detection protocol to detect link quality, and only needs to add OAM information to an obtained detection packet. In this way, not only a structure of each switch can be simplified, but also operations of each switch are simplified.
