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 10):
A system, comprising:\n a plurality of servers; a first internet protocol (IP) tunnel end point; and a second IP tunnel end point, a plurality of virtual machines, wherein a virtual machine of the plurality of virtual machines runs on each server of the plurality of servers; wherein the first IP tunnel end point is configured to:\n receive a raw packet, the raw packet being sent by a first virtual machine of the plurality of virtual machines to a second virtual machine of the plurality of virtual machines; \n replace a source IP address of the raw packet with an IP address of the first IP tunnel end point; \n generate 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; and \n send the modified packet to a second IP tunnel end point over a network; and \n wherein the second IP tunnel end point is configured to:\n receive the modified packet; \n replace the source IP address of the modified packet with an IP address of the first virtual machine; \n replace 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; \n replace the destination IP address of the modified packet with an IP address of the second virtual machine; \n replace 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 \n send the modified packet to the second virtual machine.
