Third embodiment:

The embodiments of the present invention are further explained in conjunction with specific application scenarios.

This embodiment provides a high-performance traffic distribution gateway, which can distribute mobile Internet traffic to different network elements according to policies; supports three distribution modes: distributing HTTP traffic (including accessing WAP proxy traffic) and wap1x traffic to the WAP gateway module, and The HTTP traffic is distributed to other NET management modules of the carrier, and the traffic is directly transmitted to the SP. The three distribution modes are performed according to the configuration policy. The policy matching conditions include the bearer type group (provided by the Unicom operator) and the MSISDN (Mobile Subscriber International ISDN/). PSTN number, the calling user is the number required to call a mobile subscriber in the GSMPLMN, which acts as the fixed network PSTN number; it is the only number in the public switched telephone network numbering plan that can identify the mobile subscriber), the server Group; in actual applications, the policy matching conditions can be dynamically managed, and the dynamics take effect after modification.

Compared with other solutions, this embodiment has the following main features:

Large-flow distribution is efficient, as shown in Figure 3 and Figure 4:

1. Adopt the DPDK kernel module to take over the 10G NIC carrying the traffic, and realize the large-flow data stream receiving and send;

2. The service processor adopts a virtual network technology to isolate the traffic distribution module from other service processing modules (WAP module, NET processing module) in different network planes;

3. The purpose of the traffic distribution module and the service processing module is to forward data to the virtual network plane through the Layer 2 switch. The efficiency is high. If virtual network isolation is not used, the packet is translated by the kernel module provided by the DPDK. The core protocol stack compatible data structure is sent to the service, and the kernel module provided by the DPDK is not efficient;

4. After the DPDK takes over the service traffic carrying network card, the DPDK uses the technology of lock-free ring and processing thread core binding to efficiently forward data traffic.

The traffic is distributed to different NEs according to the policy configuration, as shown in Figure 5:

S501. The O&M delivers the policy to the service.

The policy segment consists of: user number segment, bearer type, server ip, action type, etc. The number segment is saved in the tire tree, and other configuration segments are stored in the memory in the hash table. In order to facilitate dynamic update, the primary and secondary table storage is used to support the policy priority;

S502-S510, data stream distribution.

Specifically, the data stream distribution includes:

After the service obtains the data flow, the priority of the delivery policy is matched from high to low. The number of the segment group, the bearer type group, and the server information are matched in sequence. If the match is successful, the match is considered successful, and the action type of the policy is obtained.

The data stream distributes the data stream to the corresponding network element according to the matching action type and the action parameter. For example, if the action type is to distribute the WAP gateway, the destination ip and the port of the modified data packet are sent to the corresponding WAP gateway.

If the data stream fails to match, it is processed according to the default policy, and the SP is generally directly transmitted.
