Embodiment Construction

[0015] figure 1 It is a schematic diagram of the location of the network where the message forwarding device is located according to an embodiment of the present invention. The message forwarding device 110 obtains a data packet from the Internet, and determines whether the data packet is from the wireless Internet, and if the data packet is from the wireless Internet, processes the data packet so that the data packet can be applied to the service module 130 , and then evenly distribute the processed data packets to the multi-core CPU 120. Wherein, the service module 130 is any kind of network management equipment in the fixed network, such as DPI service, etc., which is used to complete various service processing functions, such as traffic identification and monitoring.

[0016] It should be noted that the message forwarding device 110 can also obtain data packets from the fixed network by judging whether the data packets it receives are tunnel link data packets to determine...

Abstract

The invention relates to a message retransmission method and a system based on a multi-core architecture. The method comprises the following steps: acquiring a data packet in the Internet; when the data packet is a tunnel link data packet, decapsulating the data packet to obtain an IP data packet; and carrying out Hash operation on the quintuple of the IP data packet, computing according to the obtained Hash value and Hash table size thereof and the number of CPUs in the multi-core CPU to obtain the corresponding CPU, labeling the Hash value into the IP data packet, and transmitting the labeled IP data packet to the CPU. The invention increases the utilization rate of fixed network equipment in the wireless Internet, realizes lock-free design of shared resources, and is applicable to the wireless Internet.

Description

technical field [0001] The invention relates to Internet technology, in particular to message forwarding in wireless Internet. Background technique [0002] According to the latest statistical report released by CNNNIC (China Internet Network Information Center), at the end of 2009, domestic mobile Internet users were 30.72 million, and in June 2010, mobile Internet users had reached 49.14 million, accounting for 11.7% of the total Internet users. It can be seen that the number of mobile Internet users in my country is huge and the number of mobile Internet users will continue to grow at a high speed. [0003] In order to cope with the rapid development of wireless Internet, telecom operators and various network product companies urgently need to quickly and seamlessly migrate existing fixed network equipment to wireless Internet. [0004] Taking DPI equipment as an example, DPI equipment is used to monitor, manage and audit the traffic of users in the network. It must use ...
