A business service providing method, wherein the business service providing method is applied to a business service providing system, the business service providing system comprises a border gateway, a virtual forwarding device, and a virtual machine, the virtual machine is configured to provide a business service for a client, and the method comprises: receiving, by the border gateway, a first overlay packet sent by a remote acceleration gateway, wherein a first service request packet is encapsulated in the first overlay packet, a source Internet Protocol IP address of the first service request packet is an IP address of the client, and a destination IP address is a public IP address associated with the virtual machine;decapsulating, by the border gateway, the first overlay packet to obtain the first service request packet, encapsulating the first service request packet to generate a second overlay packet, and sending the second overlay packet to the virtual forwarding device; decapsulating, by the virtual forwarding device, the second overlay packet to obtain the first service request packet, and sending the first service request packet to the virtual machine, characterized in that the first overlay packet carries an IP address of the remote acceleration gateway; the decapsulating, by the border gateway, the first overlay packet to obtain the first service request packet, and encapsulating the first service request packet to generate a second overlay packet further comprises: obtaining, by the border gateway, the IP address of the remote acceleration gateway carried in the first overlay packet, and setting the second overlay packet to carry the IP address of the remote acceleration gateway; and the decapsulating, by the virtual forwarding device, the second overlay packet to obtain the first service request packet further comprises: obtaining, by the virtual forwarding device, the IP address of the remote acceleration gateway carried in the second overlay packet; obtaining, by the virtual forwarding device, the source IP address of the first service request packet, wherein the source IP address of the first service request packet is the IP address of the client; and recording, by the virtual forwarding device, a correspondence between the IP address of the remote acceleration gateway and the IP address of the client. receiving, by the border gateway, a first overlay packet sent by a remote acceleration gateway, wherein a first service request packet is encapsulated in the first overlay packet, a source Internet Protocol IP address of the first service request packet is an IP address of the client, and a destination IP address is a public IP address associated with the virtual machine;decapsulating, by the border gateway, the first overlay packet to obtain the first service request packet, encapsulating the first service request packet to generate a second overlay packet, and sending the second overlay packet to the virtual forwarding device; decapsulating, by the virtual forwarding device, the second overlay packet to obtain the first service request packet, and sending the first service request packet to the virtual machine, characterized in that the first overlay packet carries an IP address of the remote acceleration gateway; the decapsulating, by the border gateway, the first overlay packet to obtain the first service request packet, and encapsulating the first service request packet to generate a second overlay packet further comprises: obtaining, by the border gateway, the IP address of the remote acceleration gateway carried in the first overlay packet, and setting the second overlay packet to carry the IP address of the remote acceleration gateway; and the decapsulating, by the virtual forwarding device, the second overlay packet to obtain the first service request packet further comprises: obtaining, by the virtual forwarding device, the IP address of the remote acceleration gateway carried in the second overlay packet; obtaining, by the virtual forwarding device, the source IP address of the first service request packet, wherein the source IP address of the first service request packet is the IP address of the client; and recording, by the virtual forwarding device, a correspondence between the IP address of the remote acceleration gateway and the IP address of the client. obtaining, by the border gateway, the IP address of the remote acceleration gateway carried in the first overlay packet, and setting the second overlay packet to carry the IP address of the remote acceleration gateway; and the decapsulating, by the virtual forwarding device, the second overlay packet to obtain the first service request packet further comprises: obtaining, by the virtual forwarding device, the IP address of the remote acceleration gateway carried in the second overlay packet; obtaining, by the virtual forwarding device, the source IP address of the first service request packet, wherein the source IP address of the first service request packet is the IP address of the client; and recording, by the virtual forwarding device, a correspondence between the IP address of the remote acceleration gateway and the IP address of the client. obtaining, by the virtual forwarding device, the IP address of the remote acceleration gateway carried in the second overlay packet; obtaining, by the virtual forwarding device, the source IP address of the first service request packet, wherein the source IP address of the first service request packet is the IP address of the client; and recording, by the virtual forwarding device, a correspondence between the IP address of the remote acceleration gateway and the IP address of the client.
