Fragmented message processing method and multi-core processor system

Abstract

The invention provides a fragmented message processing method and a multi-core processor system, which relate to the technical field of data communication and network security. The method is applied to a multi-core processor system, the system comprising a plurality of processors. The method comprises: a first processor receives a slice message to be processed, extracting the identification of theslice message to be processed, calculating an identification of the second processor according to the identification of the slice message to be processed, sending an address of a slice message to beprocessed to the second processor according to the identification of the second processor, the second processor obtains the slice message to be processed according to the address of the slice messageto be processed. The identification of the third processor is calculated according to the identification of the slice message to be processed and the network information, the address of the slice message to be processed is sent to the third processor according to the identification of the third processor, and the third processor obtains the slice message to be processed to determine the slice message to be processed for NAT conversion processing. The method effectively improves the NAT processing efficiency of the fragmented message in the multi-core processor system.

Description

technical field [0001] The invention relates to the technical fields of data communication and network security, in particular to a fragmented message processing method and a multi-core processor system. Background technique [0002] With the rapid development of Internet technology, more and more users access to the Internet to obtain various information, including the current popular Internet of Things technology is also inseparable from the support of the Internet. However, the address of the traditional Internet Protocol version 4 (Internet Protocol 4, referred to as IPv4) network is only 32 bits (bit), which can only be allocated to a limited number of users. A technology born from the problem of insufficient resources. This technology can map multiple private network addresses to one or more public network addresses, realize high reuse of network addresses, and solve the problem of insufficient address resources. In addition, Internet Protocol (Internet Protocol, refe...

Problems solved by technology

However, in the prior art, when it comes to performing NAT conversion on fragmented messages in a multi-core processor system, some of them use a separate NAT service board. This board uses a processor independent of the multi-core system. The efficiency may not be as good as the performance of multi-core processors, and in some solutions using multi-core processors, the fragmentation of the same message is processed by different central processing units (Central Processing Units, referred to as CPUs). Inter-resource mutual exclusion, locking and other operations are time-consuming and affect efficiency
