Problems solved by technology

[0003] There are two existing SNAT gateway solutions, one is a single-node SNAT gateway cluster, but a single-node SNAT gateway cannot expand horizontally
One is a multi-node stateful synchronous SNAT gateway cluster, but complex connection state synchronization is required between cluster nodes

Abstract

The invention discloses a message processing method and device, equipment and a storage medium. The method comprises the steps of dividing to-be-processed messages into a first type of messages and asecond type of messages; carrying out network address translation (NAT) on the first type of messages, and then carrying out message forwarding processing on the first type of messages by adopting a first strategy through an NAT gateway cluster; and after the NAT is carried out on the second type of messages, carrying out message forwarding processing on the second type of messages by adopting a second strategy through the NAT gateway cluster. According to the technical scheme provided by the embodiment of the invention, the messages are divided into the first type and the second type, and different forwarding strategy processing is carried out on the two types of messages, so that the existing flow of one SNAT cluster is not interrupted in the scaling process, and state synchronization isnot needed between the clusters.

Description

Technical field [0001] Embodiments of the present invention relate to the field of clustering techniques, and more particularly to a packet processing method, apparatus, device, and storage medium. Background technique [0002] The SNAT gateway cluster represents a multi-node, which is used to process the active uplink traffic from the intranet to the public network, and the data package source address SNAT is Snat Gateway The gateway cluster of the public network address on the cluster. [0003] There are two of the existing SNAT gateway scenarios, one is a single-node SNAT gateway cluster, but the single-node SNAT gateway cannot be extended laterally. One is a SNAT gateway cluster with a multi-node synchronized SNAT, but the synchronization of complex connection status is required between cluster nodes. Inventive content [0004] The present invention provides a message processing method, apparatus, device, and storage medium to achieve uninterrupted during the zooming process...
