1. A congestion control method applied to a first gateway, comprising:
monitoring node state information of a second gateway, wherein the second gateway is a collaboration gateway of the first gateway; and
in response to the node state information indicating a traffic overload of the second gateway, notifying a central gateway of the traffic overload of the second gateway, and sending a traffic collaboration request of the second gateway to an application server, wherein the traffic collaboration request is configured to request the application server to forward a traffic message of the second gateway; and
in response to the node state information indicating a service recovery of the second gateway, notifying the central gateway of the service recovery of the second gateway, and sending a service collaboration revocation request of the second gateway to the application server.
 
6. A congestion control method applied to a central gateway, comprising:
adjusting a collaboration relationship between managed gateways according to a network state of a current network, after at least one of: receiving a notification of a traffic overload of a second gateway sent by a first gateway, or receiving a notification of a traffic recovery of the second gateway sent by the first gateway, wherein the second gateway is a collaboration gateway of the first gateway, and the first gateway is configured to send a traffic collaboration request of the second gateway to an application server in response to the traffic overload of the second gateway, and wherein the traffic collaboration request is configured to request the application server to forward a traffic message of the second gateway.
 
9. A congestion control method applied to an application server, comprising:
in response to receiving a traffic collaboration request of a second gateway sent by a first gateway, performing traffic forwarding setting for the second gateway, wherein the traffic collaboration request is configured to request the application server to forward a traffic message of the second gateway;
in response to receiving a traffic collaboration revocation request of the second gateway sent by the first gateway, performing traffic forwarding revocation setting for the second gateway;
wherein the second gateway is a collaboration gateway of the first gateway.
