Embodiment Construction
[0037] The embodiment of the present invention discloses a congestion information feedback method and device, and a gateway. The core invention is that the tunnel exit device sends the measured congestion information to the export end configured according to the IP flow information export protocol, and the export end outputs the congestion information. The information is exported to the corresponding collection end, and the collection end sends the congestion information to the tunnel exit device, instead of using the data packets transmitted from the tunnel exit to the tunnel entrance to carry congestion information, so as to avoid the return flow caused by the tunnel entrance The congestion information feedback caused by data packets is not timely.
[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the...

A congestion information feedback method, device, and gateway provided by the embodiments of the present invention, after measuring and obtaining the congestion information, send the congestion information to the export terminal configured according to the IP flow information export protocol according to the IP flow information export protocol, and the export terminal Send it to the corresponding collection end, and then the collection end performs feedback, and no longer needs to carry the feedback information into the data packet for feedback. Therefore, the congestion information feedback method, device, and gateway described in the embodiments of the present invention do not need to be affected by It is limited to the data packets transmitted from the tunnel exit to the tunnel entrance, and the congestion information can be fed back to the tunnel entrance even when the tunnel entrance cannot receive the direction data packet from the tunnel exit, so when congestion occurs, the congestion information can be Feedback in time, so that congestion control can be performed in time.
Description
technical field [0001] The invention relates to the communication field, in particular to a congestion information feedback method and device, and a gateway. Background technique [0002] Tunneling is a method of passing data between networks by using the infrastructure of the internetwork. When congestion occurs in the tunnel, the tunnel exit carries the congestion information in the data packet sent to the tunnel entrance, and informs the tunnel entrance of the congestion information, so that the tunnel entrance can manage the traffic policy of the tunnel according to the congestion information. [0003] Based on the above feedback method of tunnel congestion information, when congestion occurs, but the tunnel entrance cannot receive data packets from the tunnel exit (for example, no data packets are currently transmitted to the tunnel entrance through the tunnel exit), the tunnel entrance cannot obtain congestion in time information, resulting in the inability to manage ...
