Abstract:
This application provides a packet transmission method, an apparatus, and a system in an overlay network. Network address translation and reverse network address translation are implemented at a demarcation point: an IP tunnel end point, between the logical network and the physical network, an IP option is expanded to carry a source-end network element identifier and a destination-end network element identifier, and a virtual machine in an upper-layer logical network is interconnected with a peer-end virtual machine through a lower-layer physical network by using an IP tunnel.

Claim (Index 1):
A method, comprising:\n receiving, by a first internet protocol (IP) tunnel end point, a raw packet, wherein the raw packet is being sent by a first virtual machine to a second virtual machine; generating, by the first IP tunnel end point, a modified packet according to the raw packet, wherein the modified packet identifies an IP address of the first IP tunnel end point as a source IP address of the modified packet, and identifies an IP address of a second IP tunnel end point as a destination IP address of the modified packet, and wherein the modified packet comprises a network element identifier of the first virtual machine and a network element identifier of the second virtual machine; sending, by the first IP tunnel end point, the modified packet to the second IP tunnel end point over a network; receiving, by the second IP tunnel end point, the modified packet; replacing, by the second IP tunnel end point, the source IP address of the modified packet with an IP address of the first virtual machine; replacing, by the second IP tunnel end point, a source Media Access Control (MAC) address of the modified packet with a MAC address of the first virtual machine based on the network element identifier of the first virtual machine; replacing, by the second IP tunnel end point, the destination IP address of the modified packet with an IP address of the second virtual machine; and replacing a destination MAC address of the modified packet with a MAC address of the second virtual machine based on the network element identifier of the second virtual machine; and sending, by the second IP tunnel end point, the modified packet to the second virtual machine.
