The invention relates to a forwarding control method and device, equipment and a medium, and relates to the technical field of communication. The method comprises the following steps: receiving a target data packet sent by a target terminal through a first gigabit Ethernet media access controller GMAC; wherein the first GMAC corresponds to a local area network side; under the condition that the target data packet is a first type of data packet, forwarding the target data packet through a second GMAC based on the forwarding table; wherein the first type of data packets are data packets which do not need to be processed by an application program and are forwarded based on a basic network protocol; the second GMAC corresponds to a wide area network side; under the condition that the target data packet is the second type of data packet, processing the target data packet through the application program, and forwarding the target data packet through the second GMAC after processing; wherein the second type of data packets are data packets which need to be forwarded after being processed by the application program. By adopting the method, intelligent forwarding control of the data packet can be realized.

This invention proposes a congestion state transmission method and related apparatus, relating to the field of communication technology. A memory unit stores the current flow control function state and the pending flow control function state corresponding to each receiving module. Initially, both the current flow control function state and the pending flow control function state are in a disabled state. The memory unit can acquire state detection trigger events for the target receiving module. If the target current flow control function state and the target pending flow control function state of the target receiving module are different, a first congestion state is sent to the media access controller according to the target pending flow control function state, and the target current flow control function state is updated according to the target pending flow control function state. The first congestion state characterizes the congestion state of the target receiving module, and the target pending flow control function state is set by the central processing unit according to the flow control function setting instructions sent by the user, thus avoiding atomicity issues.
