Abstract

The invention provides a message processing method and a device which are applied to a multi-core routing system including multiple processor cores. Each processor core forwards messages through a flow platform. The message processing method comprises the steps: the first processor core establishes data message forward flows through input service of the flow platform; public network addresses and public network ports which are pre-allocated for data messages are confirmed in a public network address pool through network address translation service, and the situation that the data message reverse flows do not exist in a flow table stored on the flow platform is confirmed; the flow table stored on the flow platform is locked, data message reserve pseudo flows are established and stored in the flow table, the flow table is unlocked to enable the public network addresses and public network ports not be allocated for the processor cores in the multi-core routing system except the first processor core; the data message reverse flows are established through output service of the flow platform, and the reserve pseudo flows age after the reserve flows are 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 ...
