Problems solved by technology

[0005] The present invention provides a message forwarding method, device and system, which are used to solve the inconsistency between the path of the message when the external network accesses the server through the gateway in the prior art, and the path of the response message sent by the server to the external network through the gateway , which leads to the problem that the business that depends on the path that the two-way message passes must be consistent to run cannot work normally

Abstract

The invention provides a message forwarding method, an apparatus, and a system. The method includes: a first message sent by a gateway is received and analyzed, and a source IP address and a source MAC address of the first message are obtained; a host cache table is inquired, and when the host cache table does not have a mapping relation between the source IP address and the source MAC address, the mapping relation between the source IP address and the source MAC address is saved in the host cache table; according to the first message, a response message is generated, the host cache table is inquired, and a first destination MAC address corresponding to a first destination IP address in the response message is obtained; and according to the first destination MAC address corresponding to the first destination IP address in the response message, the response message is forwarded to an external network via the gateway. According to the message forwarding method, the apparatus, and the system, as long as paths dependent on bidirectional messages are consistent, operating business can work in a normal manner.

Description

technical field [0001] The present invention relates to communication technology, in particular to a message forwarding method, device and system. Background technique [0002] In the data center, the multi-active gateway technology is usually used to solve the traffic detour problem across regions. The multi-active gateway technology means that multiple gateways can provide gateway services for servers in the same network segment at the same time. [0003] figure 1 It is a schematic diagram of a message forwarding process in the prior art. Such as figure 1 As shown, the network architecture based on the message forwarding process mainly includes: a router 11 , a first gateway 12 , a second gateway 13 , a first server 14 , a second server 15 , a third server 16 and a fourth server 17 . Wherein, the first gateway 12 and the second gateway 13 are gateways belonging to the network segment A.A.A.A / X; the first gateway 12 provides gateway services for the first server 14 and t...
