Abstract: The present disclosure relates to service satellite running status diagnosis methods and apparatuses. In one example method, a ground user terminal detects attribute information of a service beam, where the service beam is transmitted by a service satellite. If the attribute information of the service beam is abnormal, the ground user terminal generates an evaluation report of the service beam, and sends the evaluation report to a satellite controller. The satellite controller receives a plurality of evaluation reports sent by a plurality of ground user terminals, and generates a diagnosis report of the service beam based on the plurality of evaluation reports.

Abstract: A method for implementing a GRE tunnel is provided. The access device obtains an address of an aggregation gateway group including at least one aggregation gateway. The access device sends a tunnel setup request in which an address of the access device is encapsulated by using the address of the aggregation gateway group as a destination address. The tunnel setup request is used to request for setting up a GRE tunnel. The access device receives a tunnel setup accept response sent back by an aggregation gateway and obtains an address of the aggregation gateway from the response. The aggregation gateway belongs to the aggregation gateway group. The access device configures the address of the aggregation gateway as a network side destination address of the GRE tunnel. A dynamic setup of a GRE tunnel on an access network that uses an aggregation technology is implemented.

Abstract: A method includes determining a first data sending rate based on multiple round-trip times (RTTs), where the multiple RTTs include RTTs of a plurality of first probe packets sent at different sending rates, and the first sending rate is a sending rate corresponding to an RTT that is in the multiple RTTs and that is less than a first preset threshold; determining a second sending rate based on a plurality of packet loss rates, where the packet loss rates include packet loss rates of a plurality of second probe packets sent at different sending rates, and the second sending rate is a sending rate corresponding to a packet loss rate that is less than a second preset threshold; and sending a third probe packet at a third sending rate.

Abstract: A packet processing method includes receiving, by an aggregation gateway, a first tunnel establishment request message sent by a home gateway, and sending a first tunnel establishment success message to the home gateway; receiving, by the aggregation gateway, a second tunnel establishment request message sent by the home gateway, and sending a second tunnel establishment success message to the home gateway; associating, by the aggregation gateway, a first tunnel with a second tunnel according to an identifier of the home gateway; and sending a downlink packet to the home gateway by using the first tunnel and/or the second tunnel. The embodiments of the present application may increase bandwidth.

Abstract: In a method for implementing a GRE tunnel, an access device obtains an address of an aggregation gateway group including at least one aggregation gateway. The access device sends a tunnel setup request to the aggregation gateway for setting up a GRE tunnel, and the request contains an address of the access device encapsulated by using the address of the aggregation gateway group as a destination address. The access device receives a tunnel setup accept response sent back by an aggregation gateway and obtains an address of the aggregation gateway from the response. The aggregation gateway belongs to the aggregation gateway group. The access device configures the address of the aggregation gateway as a network side destination address of the GRE tunnel.
