Embodiment 1

[0114] like Figure 4 Shown, embodiment one comprises the following steps:

[0115] S401: The classifier 303 configures predefined policy rules, or receives policy rules from other logical functions, such as: policy rules from a policy and charging rules function (PolicyandChargingRulesFunction, PCRF) unit; or, the classifier also accepts the PCRF unit issued policy rules, that is, the classifier generates a service chain according to the predefined policy rules and the policy rules issued by the PCRF unit.

[0116] S402: Generate service chain information of different service chains for different service flows according to the policy rules in step S401 (predefined policy rules and / or policy rules issued by the PCRF unit);

[0117] S403: receiving data packets;

[0118] S404: The classifier 303 puts the service chain information into the data packet, and sends the data packet to the data packet processing device 301. Optionally, the data packet may also include user identifi...

Abstract

The present invention relates to the technical field of communications, and more particularly to a data packet processing apparatus and method, which are used for solving the problem of load unbalancing between instances in the same value added service (VAS) type. The data packet processing apparatus provided by an embodiment of the present invention is located in a VAS processing network, and comprises a transceiver module used for receiving a first data packet; and a processing module used for determining, according to load conditions of VAS instances corresponding to each VAS type on a service chain that the first data packet passes through, a service path that the first data packet passes through, wherein the transceiver module sends the first data packet carrying a service path identifier to a data packet routing apparatus in the network, and instructs the data packet routing apparatus to route the first data packet according to the service path identified by the service path identifier. Because the service path is determined according to the load conditions of the VAS instances, when the first data packet is routed, the load of each VAS instance is considered, and load unbalancing between the devices in the same VAS type is avoided.

Description

technical field [0001] The present invention relates to the technical field of communications, and in particular to a data packet processing device and method. Background technique [0002] In the field of fixed or mobile broadband access and data center applications, there will be many value-added service processing based on layers 4 to 7, including: anti-virus, firewall, application cache and acceleration, NAT address translation, etc. usually as figure 1 As shown in the figure, the value-added service processing equipment providing the above-mentioned value-added service processing function is connected in series behind the fixed or mobile user access equipment, and the network composed of these value-added service processing equipment and related switches and control equipment is called "value-added service processing network". ". [0003] In practical applications, NAT address translation may be required for some user service flows; only video or web access service fl...
