Abstract

The invention relates to a message forwarding method and device, a memory medium and an electronic device. A default identity of a virtual firewall is preset. A true identity of the virtual firewall corresponding to a message sent from local is stored to a session table, and shared memory design is employed for the session table. The method comprises the steps of extracting a quintuple in the message sent from the local if the message sent from the local does not carry the true identity of the virtual firewall, and searching the session table corresponding to the message sent from the local ina hash table through utilization of the quintuple and the default identity of the virtual firewall; accessing the session table to obtain the true identity of the virtual firewall corresponding to the message sent from the local if the session table is searched in the hash table; and sending the message sent from the local to a user mode, thereby sending the message sent from the local through adoption of a network card corresponding to the virtual firewall with the true identity according to a forwarding policy in the session table. The improvement of the performance of the message forwarding realized based on the virtual firewall can be facilitated.

Description

technical field [0001] The present disclosure relates to the technical field of communications, and in particular, to a message forwarding method and device, a computer-readable storage medium, and electronic equipment. Background technique [0002] In order to maximize the utilization of physical computer resources and reduce user costs, virtual firewall technology has become the research focus of various network security vendors. Virtual firewall technology can logically divide a physical firewall into multiple virtual firewall vsys (English: virtual system). From the user's point of view, each virtual firewall can be regarded as a completely independent firewall device. [0003] When forwarding packets based on the virtual firewall technology, the real identity of the virtual firewall can be obtained from the kernel state first, and then the locally sent packets can be sent to the user state, so that the user state can pass through the network card corresponding to the vi...
