Embodiment 1

[0018] This embodiment provides a method for processing data services. Such as figure 1 As shown, the method includes:

[0019] Step 101: receiving a data service message;

[0020] The network device receives the data service message, and the data service message may be a data request message sent by the terminal, or a data response message sent by the application server.

[0021] Step 102: Identify the protocol information and / or service information of the data service message;

[0022] The protocol information of the message generally includes: protocol type, etc.;

[0023] The service information of the message generally includes: the service type of the message; of course, it can also include user brand, user priority, quality of service (QoS, Quality Of Service) table, access point name (APN, Access Point Name) information, Time period, cumulative traffic, cumulative duration, bearer type, business type fields, etc.

[0024] Network devices can identify the protocol ...

Embodiment 2

[0031] This embodiment provides a network device for processing data services, such as an edge router, a network access server (NAS), a switch, a router, a firewall, and the like. Such as figure 2 As shown, the network device 200 includes:

[0032] A message receiving unit 210, configured to receive a data service message, including a data request message sent by the terminal and a data response message sent by the application server;

[0033] The message information identification unit 220 is configured to identify the protocol information and / or service information of the message, and the specific identification method can refer to step 102 in the foregoing embodiment, and will not be repeated here;

[0034] The service type mapping unit 230 is configured to map the protocol information and / or business information of the message identified by the aforementioned message information identification unit 220 to the service type field, and modify the service type value of the mes...

Embodiment 3

[0040] This embodiment provides a network system for processing data service packets. Such as image 3 As shown, the network system includes:

[0041] The application server 301 is configured to receive a data request message sent by a terminal (not shown in the figure), and send a data response message;

[0042] The network access server 302 is configured to connect the terminal to the network, and after receiving the data request message sent by the terminal, identify the protocol information and / or service information of the message, and send the data request message Protocol information and / or business information is mapped to the corresponding service type field; a flow table is established according to the mapped service type field, and the data information recorded in the flow table includes IP 5-tuples, corresponding ToS fields, etc., and will be matched to the flow table Modify the service type field of the message of the item to the corresponding service type value...

Abstract

The invention provides a data traffic processing method, a network device and a network system, wherein the data traffic processing method comprises the steps of: receiving a data traffic message; recognizing protocol information and / or traffic information of the message; mapping the protocol information and / or traffic information to a corresponding traffic type field, and modifying a traffic type value of the message according to the mapped traffic type field; and carrying out queue scheduling and forwarding on the message according to the service type value of the message. The invention hasthe advantages of effectively lowering cost of a QoS (Quality of Service) implementation scheme, preventing a traffic of falsifying high priority by a low-priority application server, and avoiding using the traffic of loading low-priority by using a high-priority port.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method for processing data services in an IP network, network equipment and a network system. Background technique [0002] The emergence of multimedia services on the IP network puts forward higher requirements on the Quality of Service (QoS) of the IP environment. Through the efforts of many IT companies, public and private networks have been rapidly developed into diversified and more challenging business combinations. Services such as packet voice, interactive TV, and streaming media on-demand on the Internet have greatly reduced costs and completely changed the communication industry. The QoS required by all these real-time multimedia applications is far higher than the best-effort service level guarantee that the Internet can provide at present. Currently, the Internet is far from delivering the reliability and performance that businesses demand and are u...
