Embodiment Construction
[0033] The present invention will be further described in detail with reference to the accompanying drawings and embodiments.
[0034] A network packet load balancing and pre-analysis method, using a many-core server, such as figure 1 As shown, including 1 switch chip, 2 multi-core processors (TILERA CPU) and 2 multi-core programmable intelligent packet engines (MPIPE);
[0035] Through the switch chip on the many-core server, the data packet load is balanced to each multi-core processor, and the network data packet reception and load balancing are realized through MPIPE on each TILERACPU, and the pre-analysis result is sent to the designated TILERACPU core. Implement load balancing through the trunk command and the rules of the hash algorithm.
[0036] After the input data packet enters the switch chip through the external interface XGBE, it is divided into two parts evenly, and correspondingly enters the two MPIPEs, and the MPIPE distributes them evenly, and distributes the...

The invention, which belongs to the network structure field of the multi-core server, provides a load balancing and preparsing method of a network data packet. The method comprises: step one, a switch chip is arranged in a multi-core server; step two, after a data packet enters the switch chip through an external interface, the data packet is distributed into two MPIPEs on average; step three, each MPIPE forwards the data packet to a corresponding TILERA CPU and preparsing is carried out; step four, a library function is invoked at each TILERA CPU and a data packet processing thread is established; step fiver, a TILERA CPU core is bound to each data packet processing thread; step six, preparsing results are distributed to the corresponding data packet processing threads; and step seven, all data packet processing threads receive the data packets based on the library functions and preparsing results are obtained, and a source IP and a target IP are stored. The method has the following advantages: load balancing of all TILERA CPUs is realized with the switch chip and the MPIPEs; and for the processing threads, data packet parsing is not needed and only the focused data packet domain is processed. Moreover, the operation becomes simple and convenient; and the processing capability of the data packet is improved.
Description
technical field [0001] The invention relates to the network structure field of many-core servers, in particular to a network data packet load balancing and pre-analysis method. Background technique [0002] The traditional method of load balancing and pre-analysis of network data packets is to analyze the data packets through the processing power of the CPU, and distribute the analysis results to the corresponding processing modules. Large CPU resources and cause the processing capability of the processing module to drop. [0003] In the existing traditional method, several many-core servers are usually selected, and then each many-core server corresponds to a multi-core processor (TILERA CPU), and information exchange between multiple many-core servers is performed through a switch, which takes up The space resources and power consumption will be relatively large. [0004] The main function of the multi-core programmable intelligent packet engine (MPIPE) adopted by the tr...
