Problems solved by technology

However, in a network, when the IP address of the intranet device changes dynamically, the IP address of the message sent from the intranet device will also change.
In this case, it is impossible to control the forwarding of packets sent by a single device based on the source IP address of the packet.

Abstract

The embodiment of the present application provides a message processing method and device. The method includes: receiving a message from an intranet device forwarded by a layer-3 network device; determining a first correspondence between each intranet device and a MAC address obtained from the layer-3 network device The first MAC address of the internal network device; in the second correspondence between the predetermined MAC address and the forwarding policy, the forwarding policy corresponding to the first MAC address is determined as the target forwarding policy corresponding to the message; according to Target forwarding strategy to process packets. By applying the solution provided by the embodiment of the present application, when the IP address of the device changes dynamically, the forwarding control of the message from the device can be realized.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a message processing method and device. Background technique [0002] In an existing network, a forwarding control device (for example, a firewall, a controller, etc.) can perform forwarding control on a message according to the attribute information of the message, so as to implement a prevention and control strategy. When performing forwarding control on a message, the forwarding policy for the message can be determined according to the quintuple information of the message and the corresponding relationship between the application carried on the protocol and the forwarding policy. This method can meet the requirements for packet forwarding control in most cases. [0003] When it is necessary to precisely control the forwarding of a packet of a single intranet device, a source Internet Protocol address (Internet Protocol, IP) address is usually used as a fi...
