In one embodiment, as shown in fig. 2, when a cloud HOST accesses a public network, traffic is first tunneled by a VM-HOST (virtual HOST) and then sent to a public network gateway active-standby cluster, EIP (elastic public network IP) mapping is performed by a public network gateway and then sent to a blast (egress gateway), and backhaul traffic is forwarded by the blast to a public network gateway HOST node, and then the public network gateway performs address mapping and then forwards to the cloud HOST. The EIP is an elastic public network IP, and the ali Yun Danxing public network IP (Internet Protocol Address internet address), that is, the EIP, is an independent public network IP resource.
Under the architecture of an under lay two-layer network, after an IGW (Internet Gateway) receives the configuration of an EIP, the IGW needs to send a GARP (Generic Attribute Registration Protocol, general attribute registration protocol) message of the EIP to Bleaf, so that the Bleaf can learn an ARP (Address Resolution Protocol ) of the EIP, and further generate a forwarding table item, so that the traffic coming from the public network can be forwarded to the public network Gateway main device normally through Bleaf.
Wherein, the underly is a physical basic layer network device of reality, and the data center is a network of a basic forwarding architecture.
In one embodiment, IGW is taken as the master device and Bleaf is taken as the upstream forwarding device. When the IGW is a master device, an EIP-GARP module of the IGW constructs a GARP message and sends the GARP message to Bleaf.

In one embodiment, the IGW listens to the udp-echo message (i.e. the loopback probe message), if the Bleaf does not loop back the udp-echo message sent by the IGW itself, indicating that the Bleaf does not process the GARP message correctly, continuing to send GARP-driven Bleaf learning of the problematic EIP through the IGW;
in one embodiment, the number of times that the IGW does not receive the udp-echo message is recorded, and if the number of times is still not received when the set number of times threshold is reached, alarm information is sent to the monitoring platform.
And S103, when the main equipment is detected to receive the loopback detection message sent by the upstream forwarding equipment, determining that the flow traction result is finished.
In one embodiment, the IGW listens to the udp-echo message, and if the Bleaf forwards the udp-echo message sent by the IGW itself back, it indicates that the EIP-GARP message sent by the IGW itself is effectively received and correctly processed by the Bleaf, which indicates that the traffic pulling result is completed.

and when the ARP table entry is an invalid table entry, discarding the loopback detection message or forwarding the loopback detection message to other devices which are not the main device.
5. The method for determining a traffic traction result based on loopback detection according to claim 1, wherein after detecting that the GARP message is successfully sent, the method further comprises, after constructing a loopback detection message based on the master device and sending the loopback detection message to the upstream forwarding device:
and when the fact that the master equipment does not receive the loopback detection message sent by the upstream forwarding equipment is detected, continuously sending the GARP message to the upstream forwarding equipment based on the master equipment so as to drive the upstream forwarding equipment to learn the GARP message, and recording the times that the master equipment does not receive the loopback detection message.
6. The method for determining traffic traction result based on loopback detection according to claim 5, wherein after the master device continues to send the GARP message to the upstream forwarding device to drive the upstream forwarding device to learn the GARP message and record the number of times that the master device does not receive the loopback detection message, further comprising:
acquiring the times that the main equipment does not receive the loopback detection message;
comparing a preset frequency threshold with the frequency of the main equipment not receiving the loopback detection message;
and when the number of times that the main equipment does not receive the loopback detection message is not smaller than the preset number of times threshold, reporting that the EIP has connectivity problem to an alarm system, and reminding operation and maintenance personnel to maintain based on the alarm system.
7. The method for determining a traffic traction result based on loopback detection according to any one of claims 1 to 6, wherein the sending the loopback detection message to the upstream forwarding device comprises:
and periodically sending and receiving the loopback detection message based on the master equipment.
8. A flow traction result determining device based on loop back detection, comprising:
the GARP message sending module is used for constructing a registration protocol GARP message based on the EIP-GARP module of the main equipment and sending the GARP message to the upstream forwarding equipment;
the loopback detection message sending module is used for constructing a loopback detection message based on the main equipment after the successful sending of the GARP message is detected, and sending the loopback detection message to the upstream forwarding equipment;
and the flow traction result determining module is used for determining that the flow traction result is finished when the main equipment is detected to receive the loopback detection message sent by the upstream forwarding equipment.
9. A computer device, the computer device comprising a memory and a processor;
the memory is used for storing a computer program;
the processor is configured to execute the computer program and implement the flow traction result determination method based on loop back detection as claimed in any one of claims 1 to 7 when the computer program is executed.
10. A computer readable storage medium, characterized in that the computer readable storage medium stores a computer program, which when executed by a processor causes the processor to implement the flow traction result determination method based on loop back detection according to any one of claims 1 to 7.
