In the embodiment of the present invention, optionally, step 301 includes:
and receiving the core network data sent by the switch through a pairing router or an SDN gateway.
It should be noted that, for the non-SDN resource pool, after the switch collects the core network data, the switch sends the core network data to the forwarding gateway in the center of the area through the service convergence switch and the pairing router in the center of the area.
For SDN resource pool, after the exchanger collects core network data, the core network data is sent to the forwarding gateway of the regional center through the service convergence exchanger and the software defined network gateway of the regional center.
According to the two resource pools, core network data do not need to pass through the light splitting equipment and the converging and distributing equipment, so that network construction is reduced, and network operation and maintenance cost is reduced.
In the embodiment of the present invention, optionally, step 301 includes:
receiving core network data which is sent by the switch and is packaged based on a general routing packaging protocol (Generic Routing Encapsulation, GRE) or a virtual extensible local area network (Virtual extensible Local Area Network, vxLAN);

since the area identifier of the source network element and the area identifier of the destination network element are the same and both indicate the first home area, the first home area is, for example, beijing city, the source network element and the destination network element both belong to the north-China district, and the forwarding gateway in the center of the north-China district returns the core network data to the receiving gateway in the beijing city.
Or under the condition that the area identifier of the source end network element and the area identifier of the destination end network element in the first information are different, respectively transmitting the core network data back to a receiving gateway of a second home zone and a receiving gateway of a third home zone, wherein the second home zone is an area indicated by the area identifier of the source end network element, and the third home zone is an area indicated by the area identifier of the destination end network element.
Further, when the area identifier of the source network element and the area identifier of the destination network element are different, the method respectively returns the core network data to the receiving gateway of the second home area and the receiving gateway of the third home area, including:

The second value is used to indicate that the source network element and the destination network element are different in the large area, and the second value may be 0.
Since the area identifier of the source network element is different from the area identifier of the witnessed network element, and the large area identifier is a second value, the source network element belongs to the second large area, and the destination network element belongs to the third large area, therefore, illustratively, the second home area is beijing city, the third home area is guangdong province, the second large area is north-China large area, the third large area is south-China large area, the forwarding gateway at the center of the north-China large area returns the core network data to the receiving gateway of beijing city, and the forwarding gateway at the center of the south-China large area returns the core network data to the receiving gateway of guangdong province.

And under the condition that the value of each item of information included in the second information is null, determining that the core network data does not need to be returned to the receiving gateways of the multiple areas.
And under the condition that the value of each item of information included in the second information is not null, determining that the core network data does not need to be returned to the receiving gateways of the multiple areas.
That is, the forwarding gateway in the center of the large area may determine, according to the second information carried by the core network data, whether the core network data needs to be returned to the receiving gateways of the multiple areas, and if the core network data needs to be returned to the receiving gateways of the multiple areas, determine the multiple areas that need to be returned, so as to return the core network data to the receiving gateways of the multiple areas.
