Abstract

The present invention provides a message processing method and device, which are applied to a multi-core routing system including multiple processor cores, and each processor core forwards a message through a streaming platform. Input the service to establish the forward flow of the data message; determine the public network address and public network port pre-assigned to the data message in the public network address pool through the network address translation service, and confirm that there is no data in the flow table saved on the flow platform The reverse flow of the message; lock the flow table saved on the streaming platform, establish the reverse pseudo-flow of the data message, save the reverse pseudo-flow in the flow table, and unlock the flow table, so that the multi-core system Other processor cores except the first processor core cannot allocate public network addresses and public network ports; the reverse flow of data packets is established through the output service of the streaming platform, and the reverse pseudo flow ages after the reverse flow is established.

Description

technical field [0001] Embodiments of the present invention relate to communication technologies, and in particular to a message processing method and device. Background technique [0002] Network Address Translation (NAT for short) technology is the process of converting the IP address in the IP packet header into another IP address. [0003] In the prior art, the NAT technology includes Internet Protocol version (Internet Protocol version, IPv4 for short) 4 / IPv4 conversion and IPv6 / IPv4 conversion, and is mainly applied to a single-core routing system. Wherein, the IPv4 / IPv4 conversion process is to translate the source IPv4 address of the IPv4 data packet into a public network IPv4 address. During the IPv6 / IPv4 conversion process, the source address of the IPv6 datagram is translated into the public network IPv4 address, and the destination address of the IPv6 datagram is translated into the destination address of the IPv4 datagram. After address translation, the final ...
